点不承认Cython [英] Pip does not acknowledge Cython

问题描述

我刚刚通过Home-brew在新的Mac OS安装上安装了pip和Python.

I just installed pip and Python via home-brew on a fresh Mac OS installation.

首先，我的pip根本没有安装依赖项-这迫使我重新运行3次"pip install table"，每次它会告诉我一个依赖项，然后我将其安装并重新运行.这是预期的行为吗?

First of all, my pip is not installing dependencies at all - which forces me to re-run 'pip install tables' 3 times and every time it will tell me a dependency and I will install that and then rerun it again. Is this expected behavior?

第二，它不接受刚才安装的Cython的安装:

Second, it does not accept the installation of Cython that it installed itself moments ago:

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

但是

$ pip install tables

推荐答案

从上游Git存储库升级Cython将解决此问题.

Upgrading Cython from the upstream Git repo will resolve the problem.

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