I'm new to symfony and while following the video tutorial, I ran into the problem. The guy in the video started his server without any problems, but for me, while trying to run php bin/console server:start I get a huge error message. Please bear with me as Im the begginer and thank you for all the help.
You're missing the DOM library. As the first comment on Installing/Configuring notices, on some linux-distributions this library is not included in the minimal PHP package.
Certain Linux distributions do not have this extension included in the
minimum PHP package. It can usually be found in one of the "optional"
php-* packages.
For CentOS, you will need to run "yum install php-xml", which provides
this extension.
As this looks like ubuntu, sudo apt-get install php-xml should do the job.

I have trawled the forum here. It suggested:
rustup self uninstall
and
sudo apt remove cargo
when running self uninstall I get:
error: rustup is not installed at '/home/dave/.cargo'
not surprising if I removed cargo is it... how do I get rid of this so I can start with a clean sheet
All I am actually trying to do is to build the salty library solokey wants, seems to have been cloned from the gitlab project but it doesnt build because it uses cargo that uses rust that is all broken for me because I followed the instructions on the net to install that.

I am running on Ubuntu.
Very nooby question, but I'm trying to install Atom text editor on Raspbian Stretch. Is it possible? I've heard because it runs on Electron, it's quite slow for Raspbian. I keep getting an error saying:
E: Unable to locate package atom
I'm following the official instructions for Debian. How can I fix this?
As of today you can't install the official package provided for Debian for its mismatching the hardware platform. Provided binary is for running on x86 hardware, but RPi doesn't come with an Intel/AMD processor, but ARM. So, you most probably need to build it from source yourself.
Primer
So, if you really want to build this from source, you should be aware of the waste of disk space caused by the IMHO poorly implemented build tool which is downloading tons of deps and copying and transpiling code around so you'll end up with 2GB+ of files with 80% accounting to dependencies, only. Since my RPi works with 8GB smartcard, only, I couldn't ever meet the need for disk space even though I was bleeding out Linux by manually removing docs, manpages, locales, ton's of outdated and mostly unused apps etc. The build also requires a whole build tooling chain, tons of dev packages for libraries, so there is a limit to milk the system ... 8GB disk drive simply isn't enough for this.
Eventually I tried moving all the files to a USB pen drive. But that drive must be formatted using a filesystem capable of symlinking. So you can't use vfat or FAT32. I didn't succeed to get a 16GB stick formatted with either version of extfs. The mkfs always ended up in a deadlock on trying to write its superblocks. Astonishingly, I couldn't even kill the mkfs with -KILL, but unplugging the drive did help in that case.
So, as a conclusion: here is a short list of steps I passed in expectation to get this working, but in the end I didn't finish due to the memory issues above. And frankly, I stopped caring ... I'd rather work with nano/vi in a terminal than using this ridiculous lego-like built software. I guess, atom is today's version of emacs with regards to the latter's acronym. Maybe you succeed with this, but I won't ...
Build from Source
Inspired by https://discuss.atom.io/t/atom-on-the-raspberry-pi/33332
Install toolchain for building native stuff
sudo apt-get install build-essential git libgnome-keyring-dev fakeroot gconf2 gconf-service libgtk2.0-0 libudev1 libgcrypt20 python rpm libsecret-1-dev xorg-dev
This set of tools was sufficient to build core files without error. Since I didn't start with a fresh installation of Raspbian there might have been some tool I have been using before, so maybe in your case there are more tools to be installed here. Look out for error messages in early stage of building and try to see if some library or header file isn't found. This mostly indicates lack of some package with name ending in -dev to be installed, too. Start by searching for the package using apt search <name-of-mentioned-library> and look for a package combining the missing library's name with suffix -dev. Then install it the usual way by invoking sudo apt-get install <package-name>.
Install up-to-date nodejs
Raspbian Stretch comes with support for NodeJS 8.11 which is basically okay. Install it and its package manager npm using this command:
sudo apt-get install node-js npm
Check installed versions with
node -v
npm -v
This should display 8.x.x on behalf of NodeJs. Use n afterwards if you want to step up:
sudo npm i -g n
sudo n lts
This will switch NodeJS to latest LTS release, which is 10.x as of now. Upgrading NodeJS is optional, but feel advised to always use latest version of npm:
sudo npm i -g npm
Check if upgrades succeeded:
node -v
npm -v
Adjust configuration of npm and install some essential dep:
sudo npm config set -g python /usr/bin/python2
sudo npm i -g node-gyp
Build Atom
Get the source. One option is to pull latest code from its repository:
git clone https://github.com/atom/atom.git
This is creating subfolder atom containing all source files. You might want to download sources of a recent release instead. But this tutorial was made with the sources fetched from Github. So make sure there is subfolder called atom containing sources similar to the ones fetched above.
It's time to start the beast:
cd atom
./script/build
This process will take a while. And it is the culprit that never finished on success in my case due to eating up all disk space over and over again.
Whenever the script fails on error, try to analyze the error, find the cause, fix it, then start the script by repeating the last command above again. If you don't remove any file in subfolder atom in between, the build script keeps passing steps of building atom it has passed successfully before.
Install atom
According to the original tutorial linked before the script should finish on success eventually. Then it's time to install with:
./script/grunt install
I guess this is causing atom to be available as a command from CLI. So, try it out. If everything looks fine you are finally ready to remove the waste of files in subfolder atom.
Feel free to report if this was working in your case.
From what I recall Atom runs 64-bit architecture; need the latest raspberry Pi.
run the following
wget https://atom.io/download/deb && dpkg -i deb
I am trying to install Sylius from here but i am unable to get it working.
On running the command i get process timed out...well...due to the ever slow internet we use here.
Could anyone please guide into installing sylius manually??
Like say manually updating vendors using composer.phar
If composer timeouts try this:
$ COMPOSER_PROCESS_TIMEOUT=300 ./composer.phar install
You can replace 300 with any number of seconds you prefer.
So I am a new to doctrine, but I am not able to install a bundle at all. I am following the guide, but the "error" which I am getting is very unusual.
Anyhow, I add this lines into deps file:
[FOSRestBundle]
git=http://github.com/FriendsOfSymfony/FOSRestBundle.git
target=bundles/FOS/RestBundle
Then I do:
./bin/vendors install
And I get:
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php5/20090626+lfs/sqlite.so' - /usr/lib/php5/20090626+lfs/sqlite.so: cannot open shared object file: No such file or directory in Unknown on line 0
Your project seems to be based on a Standard Edition that includes vendors.
Try to run ./bin/vendors install --reinstall
So on this standard way I am not able to install it at all. Can somebody explain me what is the problem, because to me it looks like, the symfony vendors script doesnt recognize changes in deps file at all.
This happens when you've downloaded the Symfony2 Standard Edition from the website. The vendor install script checks to see if the vendor directories are git repositories, and if not, will throw this error. You can fix the situation in one of two ways:
you can either run the command that it suggests: php bin/vendors install --reinstall
or, you can remove the vendors directory, then run php bin/vendors install, which amounts to about the same thing
No need to install that. Just follow the steps in the url : http://mmoreramerino.github.com/GearmanBundle/installation.html
I've got a VPS setup with Nginx & PHP5-FPM.
Being fairly new to unix, VPS etc... it took me ages to get the setup I wanted.
However Now I want to be able to install some extensions onto PHP without haveing to rebuild the entire thing. For example. Is there a way to install the php_tidy extension on an existing PHP setup?
You can compile an extensions as a shared library. Then you just have to declare your module in the php.ini.
There is a description at php.net for phpize.
Performance differences between a module and a full compilation are discussed here.
Check out the documentation at http://pecl.php.net/ on how to install PHP extensions.
It's usually as easy as running a command such as
pecl install tidy
