Question

我刚刚在全新的Mac OS安装中通过home-brew安装了pip和Python。

首先，我的pip根本没有安装依赖项 - 这迫使我重新运行'pip install tables'3次，每次它都会告诉我一个依赖项，我会安装它然后再重新运行它。这是预期的行为吗？

其次，它不接受很快就安装的Cython的安装：

$ pip show cython
---
Name: Cython
Version: 0.21
Location: /usr/local/lib/python2.7/site-packages
Requires:

但是

$ pip install tables

从上游Git仓库升级Cython将解决问题。

 pip install --upgrade git+git://github.com/cython/cython@master

Pip不承认Cython
