我将 Mac 更新到 Mountain Lion (10.8)，现在我用 Python 和 Google App Engine 开发的项目无法运行。
找到了 GAE 库，但缺少标准 Python 库（这些是 Python 库吗？）（例如cgi, logging, json).
当我打开 eclipse（有 PyDeV）时，我收到此警报：
abort: couldn't find mercurial libraries in

PYTHONPATH). Command line: hg -y debuginstall
有谁知道如何解决这一问题？
在 OS X 上 - 10.8.2
通过Python easy_install工具安装mercurial解决了问题
easy_install -U mercurial
