I'm trying to switch my Rails code from Windows to Ubuntu, and the css files have stopped working. It's the same version of the code, and the same version of rails. The only major difference that I can think of is that the Ruby version is later, but I can't see why that would affect only the css.
If I look at the html source in Windows, under application.css, I can see the different elements loaded in, one after another. Everything appears properly. However, the exact same code contains nothing on Ubuntu - just the application.css file, with require self and require tree.
There aren't any errors on the Firefox console or the terminal where I'm running rails s.
I'm guessing that it has something to do with a configuration I've made or some resource being unavailable, but without any errors, I have no idea where to start looking. Is this a Ubuntu vs Windows thing?
How do I get the css to work again?
You can try clean the asset cache from your server:
rake assets::clean
Try also run dos2unix or something - maybe the carriage returns from windows is evil on ubuntu?
find . -name -exec dos2unix {} \;

I am trying to use Run/Debug Configurations on WebStorm, however it doesn't seem to source .zshrc and produces errors about not finding commands and environment variables. (An example of this would be yarn tauri dev when using Tauri)
I have installed Ubuntu 20.04 in WSL and the project I opened in WebStorm resides under the $HOME directory. WebStorm is installed in Windows.
For the interactive shell, I have made zsh the default by chsh -s $(which zsh), but when using Run/Debug Configurations it uses the default non-interactive shell, which is dash as far as I know. And my environment variables and PATH are all set in .zshrc, which is not sourced by dash.
It seems in CLion, it is possible to execute commands in the login shell according to this YouTrack issue, but such an option is not available on WebStorm.
Is it possible to use zsh instead of dash as the default non-interactive shell? If not, it would help me a lot to know what is the best practice in such situations.
There are several questions and points you make:
First, from the question title (and the summary at the end):
Can I use zsh as the default non-interactive shell for WSL2 Ubuntu?
Well, maybe (using symlinks), but it would be a really bad idea. So many built-in scripts rely on /bin/sh pointing to Dash, or at least Bash. While Zsh might be compatible with 99.9% of them, eventually there's a strong likelihood that some difference in Zsh would cause a system-level script to fail (or at least produce results inconsistent with those from Dash).
It is possible in Ubuntu to change the default non-interactive ("system" shell) from Dash to Bash with sudo dpkg-reconfigure dash. If you select "No" in the resulting dialog, then the system will be updated to point /bin/sh to bash instead of dash.
But not to Zsh, no.
when using Run/Debug Configurations it uses the default non-interactive shell, which is dash as far as I know
I don't run WebStorm myself, so I'm not sure on this exactly. Maybe #lena's answer (or another) will cover it for you, but if it doesn't, I'm noticing this doc page. It might be worth trying to specify Zsh in those settings, but again, I can't be sure.
And my environment variables and PATH are all set in .zshrc, which is not sourced by dash.
Hmm. I'm guessing you would need these set in a .profile/.zprofile equivalent regardless. I would assume that WebStorm is executing the shell as a non-interactive one, which means that it wouldn't even parse ~/.bashrc if Bash was your default shell.
... it would help me a lot to know what is the best practice in such situations.
Best practice is probably to make sure that your ~/.profile has any environment changes needed. Yes, this violates DRY (don't repeat yourself), but it's probably the best route.
Thanks to the answer here and the discussion below, I was able to figure it out. (Thank you, #NotTheDr01ds and #lena.)
The main problem is that WebStorm is installed on Windows and therefore knows only the environment variables in Windows. There are two ways to solve the problem as follows.
Sharing WSL's environment variable to Windows through WSLENV
Add the line below to .zshrc so that it sets $WSLENV when zsh starts.
export WSLENV=VAR_I_WANT_TO_SHARE:$WSLENV
# Don't forget to insert the colon
# And for some reason, appending the variable after $WSLENV didn't work well
In Windows, run
wsl -e zsh -lic powershell.exe
This runs WSL using zsh (logged-in and interactive), then runs powershell which brings you back to Windows. Although this doesn't seem to achieve anything, by going through zsh in WSL, .zshrc was sourced and therefore $WSLENV set as well. You can check if it worked well by running the below command after you've run the above.
$env:VAR_I_WANT_TO_SHARE
Run WebStorm from the PowerShell that was just created.
& 'C:\Program Files (x86)\JetBrains\WebStorm 2022.1.3\bin\webstorm64.exe'
When you run or debug any of the Run/Debug Configurations, you will see that the environment variable is shared successfully.
Setting the PATH in Windows
For most environment variables, the previous method works well. However, PATH is an exception. The Windows PATH is shared to WSL by default. The opposite doesn't work, probably because the PATH in WSL should not interfere with Windows.I've tried adding the $PATH of WSL into $WSLENV but it didn't seem to work.
In the end, what I did was manually adding each needed $PATH of WSL into the Windows PATH.
For example, if there was export PATH=$PATH:home/(username)/.cargo/bin in .zshrc, you can then add \\wsl$\Ubuntu\home\(username)\.cargo\bin to the Windows $env:Path using the Environment Variable window.
I might have made some mistakes, so feel free to leave an edit or comments.
You can try using npm config set script-shell command to set the shell for your scripts. Like npm config set script-shell "/usr/bin/zsh".
When npm run <script name> spawns a child process, the SHELL being used depends on NPM environment. Cм https://docs.npmjs.com/cli/run-script:
The actual shell your script is run within is platform dependent. By
default, on Unix-like systems it is the /bin/sh command, on Windows it
is the cmd.exe. The actual shell referred to by /bin/sh also depends
on the system. As of npm#5.1.0 you can customize the shell with the
script-shell configuration

I am learning to program in Python and Rust. On different versions of Ubuntu these programs compiled and ran perfectly. Now that I have a dedicated Fedora 30 KDE system, every time I try and build a program, I get a warning: Failed to load module "appmenu-gtk-module"
I have tried looking this up and have re/installed anything GTK on my system. The programs otherwise function well, but no menus are drawn. I was also trying things in GNOME and hit the same thing.
I am also using QT. Those programs also build and run fine, but again, no menu.
I'm going bonkers with this. Any help is appreciated.
The appmenu-gtk module is not packaged on Fedora. (GNOME doesn't support them anyway.)
The real questions are:
Why is it configured to load? Did you copy or share GTK config files from an Ubuntu system? You should remove this module from your settings.
Even with improper configs I don't believe this should result in menus not appearing. It should just fail to load and work as normal. How is your application using menus?
I finally got so fed up with getting this error that I went full nerd-diagnosis, and ran this command to find out which file contained the errant reference to the appmenu-gtk (the package that would provide this is not installable on my system either).
(Replace "dolphin" with the command that is giving you the error.)
strace -e openat,access dolphin 2>&1 |grep -v ENOENT |awk '/appmenu-gtk/ {exit} !/appmenu-gtk/ {print}'|cut -d '"' -f2 |sort|uniq|xargs grep appmenu-gtk 2>/dev/null
This will then give you a list of files which contain the line appmenu-gtk, and in my case it was ~/.config/gtk-3.0/settings.ini. From there I just commented it out, and that gets rid of the error message (not sure if this will fix your problem of not having any menus, but you might just be able to edit that line to fix it in another way if commenting it out doesn't work).
I've been trying to automate some basic stuff with Robotframework. Here is my configuration.
Python - 2.7.10
MAC High Sierra 10.13.2
Eclipse Oxygen with RED Editor
I've downloaded Geckodriver executable and put in under several places including usr/local/bin, folder on desktop
Here is what i've tried
Setup FFDriver Set Environment Variable webdriver.gecko.driver Users/[my username]/Desktop/geckodriver
Setup FFDriver Set Environment Variable webdriver.gecko.driver usr/local/bin/geckodriver
and my test
open browser http://www.google.com firefox
I've added usr/local/bin in PATH as well and still getting "geckodriver executable needs to be in PATH" error. The same happens with Chromedriver too. I am sure I must be missing something trivial here, can someone help me out please?
Launching the eclipse from command prompt, has fixed this issue. Yes, the PATH is not being inherited when launched from desktop icon.
when you use Python. the best shortcut you can do is, put you 'geckodriver.exe' file in pythons script folder. and set the Script folder path in you system path. this will resolve your problem.
Trying to set up LESS for CSS on my Windows box, I've installed ruby and rubygems and followed the instructions exactly.
I have put teststyle.less in C:\.
When I type
lessc teststyle.less
to compile it into a .css file, I get an error:
The filename, directory name, or volume label syntax is incorrect.
Out of those familiar with LESS, do any of you have a solution to my problem?
Did I mess up the install?
If you don't want to use GUI to compile LESS on Windows, there is a clean way to get lessc command on Windows command line. It only requires you to install node.js, which is required by original lessc anyway.
So, install node.js (http://nodejs.org/) and install "less" module for node.js. The latter provides lessc executable (lessc.cmd on Windows) as well, so you should only make sure it gets under your PATH in Windows.
If you don't have node.js yet, here are step-by-step instructions:
Install node.js (http://nodejs.org/)
In new command-line, go to node.js installation directory (where node.exe is located), and execute > npm install less (make sure you do so from node.js installation directory only)
Latter downloads less module for node.js, as well as lessc.cmd to node_modules/.bin/ directory. Add this directory to PATH
Now, in new command line you may enjoy the use of lessc as usual
Source: http://pragmatictim.blogspot.fr/2012/08/developing-with-less-on-windows-getting.html
You should look at http://www.dotlesscss.org/, less ported to C# and specifically designed for .NET. You can use either a handler or compile.
Been using it for about six months, it's great.
Oops...saw windows and assumed dot net, perhaps that's not your environment. If not, never mind...
Edit:
lessc does work on Windows now. See the Github page about commandline LESS tools for installation and usage instructions. The Github page with a list of LESS GUI tools might also be interesting.
Original answer:
The lessc command line tool for less.js doesn't work on Windows. If you want command line compiling of your LESS files you should check out this post.
Also be sure to check out WinLess. WinLess is a compiler (with GUI) for LESS. WinLess can watch your LESS files, and automatically compile them when they have changed.
If you are using Visual Studio for your projects you should also check out the BuildEventScript of winless.org.
Be sure to check which compiler is being used when you are using different programs to compile your LESS code. If you are using programs which use different compilers you should watch out for interoperability issues (LESS code working correctly with one compiler, but not with another).
FYI, I found this Windows command line tool to compile LESS into CSS useful. It uses less.js to do the compilation. The command syntax is not very graceful, but it works well.

I just started using Crunch to compile Bootstrap and its pretty awesome. Its built on Adobe Air, which you will have to install if you don't already have it.
I think I found the problem. In my first installation I installed to C:\Program Files\Ruby
so I uninstalled and tried the default 'C:\Ruby' install path. Seems to fix the problem and it now works correctly. Thanks.
I have a recompiled version of DotlessCss that can accept less code from standard input and output the css code to the standard output. I have attached it at the following link LESS CSS Compiler for Windows
Only this https://github.com/leafo/lessphp PHP compiler didn't crashed with my crazy project structure with CSS imports in LESS, etc.
Very simple shell command for compiling LESS to CSS:
plessc input.less > output.css
You can use Prepros App for windows. It can compile less, sass, jade, stylus, markdown, coffeescript and haml with live browser refresh.
I'm trying to build an application from source in windows that requires some Unix tools. I think it's the apparently standard ./configure; make; make install (there's no INSTALL file). First I tried MinGW but got confused that there was no bash, autoconf, m4, or automake exes in \bin. I'm sure I missed something obvious but I installed Cygwin anyways just to move forward. For some reason when I run
sh configure.sh
I get:
platform unix
compiler cc
configuration directory ./builds/unix
configuration rules ./builds/unix/unix.mk
My OS has identity problems. Obviously the makefile is all wrong since I'm not on unix but win32. Why would the configure script think this? I assume it has something to do with Cygwin but if I remove that I can't build it at all. Please help; I'm very confused.
Also is it possible to build using MinGW? What's the command for bash and is mingw32-make the same as make? I noticed they're different sizes.
Everything is fine. When you are inside CygWin, you are basically emulating an UNIX. sh runs inside CygWin, and thus identifies the OS correctly as Unix.
Have a look at GCW - The Gnu C compiler for Windows
Also, you might be interested in this help page, that goes into some detail about the minimal system (MSYS), such as how to install, configure et. c.
That should help you get bash, configure and the rest to work for MinGW as well.
From the Cygwin home page
Cygwin is a Linux-like environment for Windows. It consists of two parts:
A DLL (cygwin1.dll) which acts as a Linux API emulation layer providing substantial Linux API functionality.
A collection of tools which provide Linux look and feel.
Since configure is using the Cygwin environment, it is interacting against the emulation layer and so it is just like it's working on a Unix environment.
Have you tried building the application and seeing if it works?
