我在开始使用 GAE（OS X 10.6.8 和 Python 2.7 上的 1.7.6）时遇到问题，与亚马逊服务相比，它非常糟糕。但是，我想至少部署示例应用程序。在解决了其他问题之后，我现在准备好部署一个小型示例应用程序。当我尝试部署它时，我收到如下 SSL 错误：

If deploy fails you might need to 'rollback' manually.

在另一个线程中对此有一些建议，指出您需要删除 cacerts.txt，尽管我无法在 OS X 上找到此文件。此外，为了上传代码，我必须删除一个 cacert 文本文件。但也许我是个白痴。

我在这里面临的另一个问题是，由于管理 python 版本的困难，OS X 不能很好地与 GAE 一起工作。在安装了多个版本的 python、EPD、ActiveState、MacPorts 之后，我现在手头一团糟。尽管有保证，但这些都不能解决我早期的问题。这真是谷歌应用管理的状态，实在是太骇人听闻了。看起来 GAE 似乎是由一群来自 90 年代中期微软的人构建的......任何关于上述问题的建议将不胜感激。干杯

错误中的第四行。链接下的相关说明。

确保（来自文档）：

To do this you must have the ssl Python module installed on your system.

解决方法--skip_sdk_update_check=yes：运行时使用命令行参数dev_appserver.py。

我遇到了同样的问题，并注意到--skip_sdk_update_check=yes每次启动应用程序时都会使用 GUI 工具 (GoogleAppEngineLauncher)。这是从 SDK 1.8.7 开始的。

根本原因似乎是GAE 开发服务器的模块白名单系统中的一个已知错误。即使您安装了ssl模块（如文档所述是必需的），也ssl依赖于_ssl未列入白名单的模块。这就是为什么您可以import ssl毫无问题地在常规 python shell 会话中执行，但在 GAE 应用程序中执行同一行时会出错。
