When you run Magento 2 CLI command "bin/magento ..." and get the error:
Allowed memory size of xxxx bytes exhausted (tried to allocate xxx bytes)
You can easily fix it using instead of bin/magento this command:
php -dmemory_limit=-1 bin/magento ....
If you have installed or updated Magento 2 extension and received the error message e.g.:
Module 'Company_Module' from 'app/code/Company/Module' has been already defined in 'vendor/company/module'.
this means that you have 2 versions of the extension:
1) in the folder app/code/Company/Module
2) in the folder vendor/company/module
In vendor folder Magento stores all components (extensions, themes, language packages) that have been installed using Composer.
As installing or updating extensions via Composer is preferred, you need to remove extension folder app/code/Company/Module (please don't forget about a backup before removal) and run installation commands.
If you receive the error message "No such entity.", "No such entity with" or "No such entity with customerId" in Magento 2, the issue usually occurred when you try to load not existing object via Magento 2 Repository Class.
To debug this issue, please open the file
vendor/magento/framework/Exception/NoSuchEntityException.php
If you receive the error:
Please upgrade your database: Run "bin/magento setup:upgrade" from the Magento root directory. The following modules are outdated: Vendor_Module schema: current version - x.x.x, required version - z.z.z Vendor_Module data: current version - x.x.x., required version - z.z.z
And you have already run these commands:
composer update vendor/module-name
bin/magento setup:upgrade
If you use Magento 2.2.x and get the error like:
