composer update failed with "Failed to set PHP CodeSniffer installed_paths Config"

Question

New to magento

I wanted to upgrade my Magento to 2.4.4 . Using php 7.4 with Ubuntu 20.04 and nginx

composer -vvv update

I get this:

Dependency resolution completed in 0.003 seconds

Failed to set PHP CodeSniffer installed_paths Config

so I go to the directory /var/www/magento2/vendor/squizlabs/php_codesniffer and run the command '/usr/bin/php7.4' -d allow_url_fopen='1' -d disable_functions='' -d memory_limit='-1' ./bin/phpcs --config-set installed_paths ../../magento/magento-coding-standard,../../phpcompatibility/php-compatibility

I get:

PHP Warning:  require(/var/www/magento2/vendor/composer/../../app/etc/NonComposerComponentRegistration.php): failed to open stream: No such file or directory in /var/www/magento2/vendor/composer/autoload_real.php on line 59
PHP Fatal error:  require(): Failed opening required '/var/www/magento2/vendor/composer/../../app/etc/NonComposerComponentRegistration.php' (include_path='/var/www/magento2/vendor/magento/zendframework1/library:.:/usr/share/php') in /var/www/magento2/vendor/composer/autoload_real.php on line 59

clearly this is a path issue with my composer and I do not have any NonComposerComponentRegistration.php

How do I correct this path issue? should I just uninstall composer and reinstall it? hopefully this won't affect my magento install.

Answer 1

I deleted the vendor folder completely. Reset the permissions of all files. the sudo composer install and it solved my issue.

Answer 2

simple case:

From the html directory run vendor/bin/phpcs --config-show
If installed_paths is not listed, or is incorrect run the following:

vendor/bin/phpcs --config-set installed_paths ../../magento/magento-coding-standard,../../phpcompatibility/php-compatibility

case with code or module issues:

If vendor/bin/phpcs --config-show shows no output there could be an error in a module or a deployment problem.
Run phpdbg vendor/bin/phpcs --config-show
At the prompt press r, capture the error, quit, and then correct the error.

For example, in the output below, I had a cached module that was incompatible with a pending update. Removing the cached module cleared the error.

$ phpdbg vendor/bin/phpcs --config-show

Config value "installed_paths" added successfully

$ vendor/bin/phpcs --config-show
Using config file: /var/www/magento/html/vendor/squizlabs/php_codesniffer/CodeSniffer.conf

installed_paths: ../../magento/magento-coding-standard,../../phpcompatibility/php-compatibility

Now composer update proceeds without this error.
