使用dev_appserver.py进行本地开发时，我无法在AppEngine标准PHP上运行我的PHP应用程序。
我得到的错误：/Users/xxx/php/php.ini
PHP Warning: session_start(): Failed to read session data: user (path: Memcache) in /Users/xxx/php/index.php on line 52
我的index.php调用session_start();，发生此错误。
我的app.yaml文件没有什么特别的，因为它仅包含运行时php72。
我了解到appengine标准使用memcached进行会话管理，因此我从php.ini中删除了cache_handler文件以使其回退为默认值，但仍然收到此错误。有什么想法吗？
教程/文档没有列出我需要设置的任何特殊内容。
