我正在为 Magento 开发一个模块，它调用 Web 服务并添加 cookie。我希望在保存用户时调用类中的方法( customer_save_after )。在本地主机上开发时，我以某种方式能够让它工作，但我在尝试实现它的实时站点上收到此错误:
Mage registry key "_singleton/Eight18_Aqui4_Model_Observer" already exists
有一个类似的线程 here ，但它忽略了如何解决问题的实际细节。
这是我的 config.xml: (customer_save_after 事件似乎是错误开始的地方)

最后是 system.log 文件:

最佳答案
简短版本:您的生产系统正在“编译器模式”下运行，并且您尚未编译模块类。
您的生产服务器正在运行，且 Magento 的“compiler mode ”(自链接)已打开。您可以通过 Magento 的日志记录错误消息来判断
ERR (3): Warning: include(): Failed opening '/var/www/clients/client3/web4/web/includes/src/Eight18_Aqui4_Model_Observer.php'
for inclusion (include_path='/var/www/clients/client3/web4/web/includes/src:.:/usr/share/php:/usr/share/pear') in /var/www/clients/client3/web4/web/includes/src/Varien_Autoload.php on line 93
Magento 在 includes/src 中查找类。这就是编译类的放置位置。此外，PHP 尝试包含完全下划线的文件名 Eight18_Aqui4_Model_Observer.php。仅当编译器模式打开时才会发生这种情况。
当您将模块更改推送到生产环境时，您需要重新编译模块。您可以从
执行此操作System -> Tools -> Compilation
或者使用命令行编译脚本
$ php shell/compiler.php
Usage: php -f compiler.php -- [options]
state Show Compilation State
compile Run Compilation Process
clear Disable Compiler include path and Remove compiled files
enable Enable Compiler include path
disable Disable Compiler include path
