Question

我正在关注google cloud intro for python apps。

我正在使用一个简单的烧瓶应用程序，类似于页面中的示例，并添加了用于postgres的psycopg2 python库。

在google SDK dev_appserver.py脚本下运行时，会抛出以下堆栈。我相信正在发生的事情是dev_appserver.py脚本充当沙箱并且不允许导入psycopg2的本机代码方面 - 可能是因为本地代码不允许在google python app infra上（_psycopg2.pyd在psycopg2安装）

我不明白的是，postgres是针对谷歌云SQL的测试版，谷歌的similar guide表示支持psycopg2。

但我收到以下错误：

ImportError：没有名为psycopg2._psycopg的模块，带有google cloud sdk dev_appserver.py脚本
