Setting an invalid installed path breaks all commands

[stuporglue]

I tried to set two installed paths like so:

phpcs --config-set installed_paths ~/projects/wpcs/:/usr/local/etc/php-code-sniffer/Standards

And now everything is coming up:

admin:~$ phpcs  -i
PHP Fatal error:  Uncaught UnexpectedValueException: DirectoryIterator::__construct(/Users/admin/projects/wpcs/:/usr/local/etc/php-code-sniffer/Standards): failed to open dir: No such file or directory in /usr/local/Cellar/php-code-sniffer/3.0.0/src/Util/Standards.php:84

I can't use --config-delete

admin:~$ phpcs --config-delete installed_paths
PHP Fatal error:  Uncaught UnexpectedValueException: DirectoryIterator::__construct(/Users/admin/projects/wpcs/:/usr/local/etc/php-code-sniffer/Standards): failed to open dir: No such file or directory in /usr/local/Cellar/php-code-sniffer/3.0.0/src/Util/Standards.php:84
Stack trace:
#0 /usr/local/Cellar/php-code-sniffer/3.0.0/src/Util/Standards.php(84): DirectoryIterator->__construct('/Users/admin/pr...')

and I don't know what to do.

I can't find where the config file is located, or I'd just delete it or edit it by hand. How can I fix this?

[stuporglue]

I found that the file name is CodeSniffer.conf and found where it was using Xdebug (/usr/local/Cellar/php-code-sniffer/3.0.0/CodeSniffer.conf, since I installed using Brew).

It would be convenient if instead of crashing, PHPCS would catch the error and maybe indicate which file the bad path came from.

I'm glad you found the file and were able to resolve this manually. I've committed a fix so that invalid paths don't break PHPCS any more. Thanks for reporting this.
