Fatal error: Uncaught ValueError: Path cannot be empty in phar:///home/user/.local/bin/phpcs.phar/src/Reporter.php:3

Hello,

I just fetch PHPCS and PHPBCF phar files with curl.

Just tried to run it :

(devbox) user@user-ow2:~/git/OW2/umdev-fd (improvements) $ phpcs.phar user-account-create.php 

Notice: tempnam(): file created in the system's temporary directory in phar:///home/user/.local/bin/phpcs.phar/src/Reporter.php on line 3

Fatal error: Uncaught ValueError: Path cannot be empty in phar:///home/user/.local/bin/phpcs.phar/src/Reporter.php:3

#4 {main}
  thrown in phar:///home/user/.local/bin/phpcs.phar/src/Reporter.php on line 3

I did not found anything able to help me in wiki/issues. Any hint ?

@NoxInmortus I cannot reproduce the issue, but based on the error message, it sounds like your system temp directory (sys_temp_dir ini value) is misconfigured or unwrittable, resulting in tempnam() returning false.

Also cannot reproduce. Closing due to lack of feedback.

very weird, but I also get the same error

in my case it worked in docker, but after some changes and rebuilding the image, I cannot run it anymore:

# ./vendor/bin/phpcs
PHP Notice:  tempnam(): file created in the system's temporary directory in /vendor/squizlabs/php_codesniffer/src/Reporter.php on line 159

The issue was in temp env variable exported from host: TMPDIR=/var/folders/v_/4d7tl7nj28q37zyztkwqw4dh0000gn/T/ After removing this var phpcs works again

@tosiara Thanks for adding that info. Hopefully it will help someone else running into this in the future.
