Pip无效命令egg_info

Question

我最近升级了pip，它破坏了一些东西。

我试着运行这个：

    sudo pip install -U ipython pyzmq
    Requirement already up-to-date: ipython in /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages
    Downloading/unpacking pyzmq
      Downloading pyzmq-14.5.0.tar.gz (997kB): 997kB downloaded
      Running setup.py (path:/private/tmp/pip_build_root/pyzmq/setup.py) egg_info for package pyzmq
        usage info....


    error: invalid command 'egg_info'

奇怪的是，setuptools并没有被找到，而是被安装了。

    ➜  ~  which setuptools
          setuptools not found

我和你有同样的问题(也是在Mac上)。我从~/env-backend/backend/lib/python2.7/site-packages中删除了(rm -r)所有安装了setuptools的文件和文件夹(ls | grep setup)。

然后，我使用来自python.org (> curl https://bootstrap.pypa.io/ez_setup.py -o - | python)的curl指令安装了setuptools，此后它对我来说工作得很好。
