Question

我在开始使用GAE（使用Python 2.7的OS X 10.6.8上的1.7.6）时遇到了问题，并且与亚马逊服务相比，它非常糟糕。但是，我想至少部署示例应用程序。在完成其他问题之后，我现在有一个可以部署的小样本应用程序。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.

在另一个线程中有一些建议说明你需要删除cacerts.txt，虽然我无法在OS X上找到这个文件。而且，为了让代码上传我似乎迟钝了d必须删除cacert文本文件。但也许我是个白痴。

我在这里遇到的另一个问题是，由于管理python版本的难度，OS X与GAE不兼容。在安装了python，EPD，ActiveState，MacPorts的多个版本后，我手上已经弄得一团糟了。尽管他们愿意，但这些都没有解决我早期的问题。这是谷歌应用程序管理的状态真的很可怕。看起来GAE是由一群来自90年代中期微软的人建造的......对于上述问题的任何建议都将非常感激。干杯

Answer 1

错误结束后的第四行。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.

Answer 2

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

我遇到了同样的问题，并注意到每次启动应用时，GUI工具（GoogleAppEngineLauncher）都会使用--skip_sdk_update_check=yes。这是SDK 1.8.7。

根本原因似乎是GAE开发服务器模块whiltelisting系统中的known bug。即使您安装了ssl模块（正如文档中所述），ssl也依赖于_ssl，而import ssl未列入白名单。这就是为什么你可以在常规的python shell会话中执行{{1}}而没有问题，但是当你在GAE应用程序中执行相同的行时会出错。
