Question

我是app引擎的新手，并尝试部署python应用程序。当我在本地主机上预览时，该应用程序正常工作，但当我部署它时，我收到以下错误：＆＃34;内部服务器错误

服务器出错或无法执行请求的操作。＆＃34;

并追溯：

如果这是应用程序的新/最近部署，则新添加/修改的索引仍然可以构建，条件是暂时的，最终会消失。请参阅此答案：https://stackoverflow.com/a/29807764/4495081。

在某些情况下，本地开发服务器不会自动生成建议的索引。检查本地索引文件中是否存在建议的索引。如果遗漏，请手动添加。

在某些情况下（例如某些多模块应用程序），应用程序部署也不会自动上载本地应用程序索引文件。如果开发人员控制台中显示的索引与您在本地索引文件中看到的索引不匹配，则应使用update_indexes appcfg.py选项明确部署它们。
