我知道已经有很多关于这个错误的帖子，但我的问题似乎很独特，至少从我的角度来看是这样。请证明我错了！我正在使用 Python 2.7，导入 jinja2，并通过from google.appengine.ext import db. 我的其他不导入这些包的更简单的应用程序部署得很好，但是这个会抛出一个Error: Server Error. 这可能与我的代码有关，还是 Google 的问题？似乎这是这些天常见的错误，但似乎也有很多诊断。但是，由于我的一些应用程序部署而不是其他应用程序，这是可疑的。谢谢。
--一些额外的信息--
正如我在评论中所说，本地运行正常，部署引发服务器错误。
**本地运行后的日志输出：

--UPDATE-- 原来我有一个变量命名错误，当它被清除后，不再出现 500 服务器错误。我希望抛出的错误更能说明问题，因为它们通常不包括这种特殊情况。经验教训 - 如果您发现自己处于这种情况，那肯定是您的代码中的错误。谢谢大家的帮助。
