I have uploaded my Puppeteer script to Heroku but I do not know how to specify the executable path for chrome.exe. I am able to do this easily on my local machine like so:
executablePath: 'C:\\Program Files\\Chromium\\Application\\chrome.exe'
But I do not know how to get around this error on my Heroku dyno:
Error: An executablePath or channel must be specified for puppeteer-core
Please feel free to provide any input as I am brand new to programming and want to learn as much as possible.
I have downloaded the puppeteer buildpack. Chromium is installed. I just want to know how to specify the executable path.

I'm interested in learning about kde environment. So I read the contribution page on wiki, git cloned the kompare repo and built it. But an attempt to execute the binary gave me an error saying Could not load our KompareNavigationPart. The console showed the following error about kservice:
> ./kompare
kf5.kxmlgui: cannot find .rc file "kompareui.rc" for component "kompare"
kf5.kservice.services: KMimeTypeTrader: couldn't find service type "Kompare/ViewPart"
Please ensure that the .desktop file for it is installed; then run kbuildsycoca5.
kf5.kxmlgui: cannot find .rc file "kompareui.rc" for component "kompare"
Aborting aboutToFinish handling.
I couldn't find anything about it in the readme or the project wiki. I've installed the kde-development-meta package on arch linux. Can anyone help me get started with development on kde platform?
Short answer: Use "cmake -DCMAKE_INSTALL_PREFIX=/usr" and "make install".
Long answer: It looks like you tried to run from the build directory, but the KDE plugin loader does not look there by default. You could adjust the various path variables to additionally point to your build directory. The variables are mentioned at https://community.kde.org/Guidelines_and_HOWTOs/Build_from_source#Set_up_the_runtime_environment
You can also use "make install" to install to a run-time directory. If you did not change the defaults of cmake via -D option, this will be "/usr/local/", and in this case you also have to adjust the various path variables to include that directory, unless your distribution already configured this for you.
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.
I am trying to follow this tutorial, in order to install the Nix package manager in my home directory instead of /nix.
I am doing the PRoot installation (see 2. in tutorial). At the end, the
tutorial proposes to be smart in Building native packages section, to be
able to run packages without PRoot:
To run packages natively (without PRoot) they have to be build from source because all paths to the nix store are hard-coded. It is simple, really:
mkdir $HOME/nix
nix-channel --update
env NIX_STORE_DIR=$HOME/nix nix-env -i nix
And now your Nix store gets built up using the new paths. The built binaries can be run directly from there.
I did that, but I don't see how it frees me from PRoot. If I don't do the /nix mounting point with PRoot, nothing works (no nix-env executable,
I can't install new packages).
Should this NIX_STORE_DIR environment variable be put in my .bashrc ?
It seems I always need to run PRoot because ~/.nix-profile points to
a /nix/... directory:
.nix-profile -> /nix/var/nix/profiles/default
There are more steps in the tutorial (5., 6.) - should I follow them ? It seems they apply only in case of using the manual installation (step 4.),
although it is not explicit.
Any help would be appreciated :)
For anyone stumbling on this old question: there is no currently supported way to install Nix without root. The above wiki was moved to https://nixos.wiki/wiki/Nix_Installation_Guide . It may well be out of date. PRoot could work, but even then, rebuilding the whole store at a different path is not a good idea, not the least because the binary caches won't help and you'll need to build everything.
I suggest trying Nix in a virtual machine or cloud server.
Future people from Google, it's still unsupported but does work. Script here that installs a couple dependencies, builds a temporary Nix, and uses that to install a proper version in your directory of choice.
I'm trying to set up a python like environment with Atom-editor on a Linux machine.
I find the autocomplete-python package that uses jedi.
In the settings of the package I tried to add some python path where the APIs are (/usr/lib/python2.7/dist-packages/) but then the autocompletion doesn't recognize these libraries (for example the PyQt ones)
Am I missing something?
For anybody having the same issue please look here.
Basically everything should work out of the box, but if it does not -- try to configure path to python executable with which you have installed your external module. If it's still fails to complete -- try to configure extra path to python modules. (usually your site-packages directory)
I am trying to compile Network.HTTP (http://hackage.haskell.org/package/network) on win32/cygwin. However, it does fail with following message:
Setup.hs: Missing dependency on a foreign library:
* Missing (or bad) header file: HsNet.h
This problem can usually be solved by installing the system package that
provides this library (you may need the "-dev" version). If the library is
already installed but in a non-standard location then you can use the flags
--extra-include-dirs= and --extra-lib-dirs= to specify where it is.
If the header file does exist, it may contain errors that are caught by the C
compiler at the preprocessing stage. In this case you can re-run configure
with the verbosity flag -v3 to see the error messages.
Unfortuntely it does not give more clues. The HsNet.h includes sys/uio.h which, actually should not be included, and should be configurered correctly.
Don't use cygwin, instead follow Johan Tibells way
Installing MSYS
Install the latest Haskell Platform. Use the default settings.
Download version 1.0.11 of MSYS. You'll need the following files:
MSYS-1.0.11.exe
msysDTK-1.0.1.exe
msysCORE-1.0.11-bin.tar.gz
The files are all hosted on haskell.org as they're quite hard to find in the official MinGW/MSYS repo.
Run MSYS-1.0.11.exe followed by msysDTK-1.0.1.exe. The former asks you if you want to run a normalization step. You can skip that.
Unpack msysCORE-1.0.11-bin.tar.gz into C:\msys\1.0. Note that you can't do that using an MSYS shell, because you can't overwrite the files in use, so make a copy of C:\msys\1.0, unpack it there, and then rename the copy back to C:\msys\1.0.
Add C:\Program Files\Haskell Platform\VERSION\mingw\bin to your PATH. This is neccesary if you ever want to build packages that use a configure script, like network, as configure scripts need access to a C compiler.
These steps are what Tibell uses to compile the Network package for win and I have used this myself successfully several times on most of the haskell platform releases.
It is possible to build network on win32/cygwin. And the above steps, though useful (by Jonke) may not be necessary.
While doing the configuration step, specify
runghc Setup.hs configure --configure-option="--build=mingw32"
So that the library is configured for mingw32, else you will get link or "undefined references" if you try to link or use network library.
This combined with #Yogesh Sajanikar's answer made it work for me (on win64/cygwin):
Make sure the gcc on your path is NOT the Mingw/Cygwin one, but the
C:\ghc\ghc-6.12.1\mingw\bin\gcc.exe
(Run
export PATH="/cygdrive/.../ghc-7.8.2/mingw/bin:$PATH"
before running cabal install network in the Cygwin shell)
