如何在App Engine开发服务器(OS X)内部导入PyCrypto？

Question

我的app.yaml包括以下几行：

libraries:
- name: pycrypto
  version: "2.6"

我有正确的PyCrypto版本：

$ python
>>> import Crypto
>>> Crypto.__version__
'2.6'

但是当我在GAE Development SDK交互控制台中尝试评估import Crypto时，我得到的结果是：

Traceback (most recent call last):
  File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/tools/devappserver2/python/request_handler.py", line 225, in handle_interactive_request
    exec(compiled_code, self._command_globals)
  File "<string>", line 12, in <module>
ImportError: No module named Crypto

因为pycrypto包含本机编译的代码，所以在安装Python时需要自己安装它。假设您已经安装了pip：

pip install pycrypto
