Q:/usr/bin/env: ‘php ’: No such file or directory

A:php bin/magento list

Q:Warning: Invalid argument supplied for foreach() in /var/www/html/vendor/ma gento/module-eav/Model/Config.php on line 341

A:Two ways to fix this issue.Fixed it by changing the line 96 in this file vendor/magento/module-config/Model/Config/Structure/Converter.php. Actual Code: if ($children->length && trim($child->nodeValue, " ") === '') { Corrected Code: if ($children->length && trim($child->nodeValue, " ") === '') { Check if your XML file has any tab spacing within it. If so, remove the tab spacing and replace them with normal single spaces.
