GAE 无法在 virtualenv 中导入 Web.py 模块

Question

我正在尝试在 virtualenv 中设置一个 Web.py (0.37) 项目以在 Google App Engine (1.7.2) 上运行，但我从应用服务器获得了 ImportError: No module named web。

我已经在我的 virtualenv 中使用python setup.py install 安装了 web.py，并且可以确认它已正确安装，因为我可以从 python 解释器中导入它。

我的实际 GAE 文件夹位于 virtualenv 之外，但链接如下：

ln -s ~/Development/google_appengine $VIRTUAL_ENV/google_appengine

并在$VIRTUAL_ENV/lib/python2.7/site-packages/gae.pth 中添加到我的python 路径

我必须缺少一个额外的步骤，这是错误消息：

应用引擎不允许您从站点包中导入第 3 方模块；您必须将 web.py 复制到您的应用目录中。
