python - Pip 无效命令 Egg_info

Question

我最近升级了 pip，它破坏了一些东西。

我尝试运行这个:

    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 未找到但已安装。

    ➜  ~  which setuptools
          setuptools not found

我也遇到了和你一样的问题(也在 Mac 上)。我删除了(rm -r)来自 ~/env-backend/backend/lib/python2.7/site-packages 中包含 setuptools 的所有文件和文件夹( ls | grep 设置)。

然后我使用python.org中的curl指令安装了setuptools (>curl https://bootstrap.pypa.io/ez_setup.py -o - | python)此后对我来说效果很好。
