每次我尝试启用或禁用任何模块时，Magento 2都会崩溃

Question

我有Magento 2.3.3，它托管在MageMojo Stratus上。

每次我尝试安装、启用或禁用任何模块时，前端都会正常工作，但我在管理面板中遇到了一个不可恢复的错误：

<b>Fatal error</b>:  Uncaught Error: Call to a member function getNext() on null in /srv/public_html/generated/code/Magento/User/Model/User/Interceptor.php:529
Stack trace:
#0 /srv/public_html/vendor/magento/module-backend/Model/Locale/Manager.php(96): MagentoUserModelUserInterceptor-&gt;getInterfaceLocale()

#2 /srv/public_html/vendor/magento/framework/Locale/Resolver.php(83): MagentoBackendModelLocaleResolver-&gt;setLocale(NULL)

我已经尝试了众所周知的以下步骤和我能想到的每一种可能的变化：

magento maintenance:enable
magento cache:disable
rm -rf generated/ var/view_preprocessed/ var/composer_home/cache/ var/cache/ var/page_cache/
magento setup:upgrade
composer install
magento setup:di:compile
magento setup:static-content:deploy -f
magento indexer:reindex
magento cache:flush
magento cache:enable
magento maintenance:disable

Answer 1

问题似乎有两个方面：

1. 要正确删除所有生成的内容，命令应为：

rm -rf generated/* var/di/* var/cache/* var/page_cache/* var/view_preprocessed/* var/composer_home/cache/* pub/static/*

2. 在MageMojo的Mojo Stratus主机上，您需要同时清除Varnish缓存、Redis缓存、PHP OP缓存和AWS CloudFront存储。服务器上有一个helper cli工具，您可以使用：

...
php bin/magento cache:flush
/usr/share/stratus/cli cache.all.clear
