PHP Code Sniffer not working: Interface 'PHP_CodeSniffer_Sniff' not found

Hello,

Does it work fine when running Code Sniffer from command line?

Good question, Vladimir.
No, it does not.
Something with running

php composer.phar update

or anything similar I forgot for CodeSniffer to work?

I would suggest to follow installation steps from https://github.com/squizlabs/PHP_CodeSniffer again, just to be sure.

I've just installed PHP_CodeSniffer and the moodle-local_codechecker, following the given instructions, and I'm having the same issue. PhpStorm outputs the following error:

phpcs: PHP Fatal error:  Interface 'PHP_CodeSniffer_Sniff' not found in /vagrant/public/local/codechecker/moodle/Sniffs/Commenting/InlineCommentSniff.php on line 27

I'm running Moodle on a LEMP vagrant box with PHP 7.0.22 and PHP_CodeSniffer version 3.1.0 (stable).

Did you find any solution to this problem?

Hi,

Do you also have issues with running it via command line?

No I couldn't get the moodle-local_codechecker plugin to work with PHP_CodeSniffer via the CLI either.

I eventually got it all working by installing the php-codesniffer package via Ubuntu. I had previously been installing it via composer and that didn't seem to work when used in conjunction with the moodle-local_codechecker plugin.

Thanks for sharing that!

Note to myself, the steps to circumvent the error and getting phpcs to work

brew uninstall --force php-code-sniffer
brew install php-code-sniffer@2.9
echo 'export PATH="/usr/local/opt/php-code-sniffer@2.9/bin:$PATH"' >> ~/.bash_profile
ln -s /usr/local/opt/php-code-sniffer@2.9/bin/phpcs /usr/local/bin/phpcs

Luca - you saved me a lot of time here. Remind me to buy you a beer at Moodle Dach 2018!
