python - pip 无效命令egg_info

我最近升级了点子，它弄坏了东西。

我尝试运行此：

    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，找不到并安装了setuptools。

    ➜  ~  which setuptools
          setuptools not found

最佳答案

我遇到了和您一样的问题（在Mac上也是如此）。我从其中安装了setuptools（rm -r）的~/env-backend/backend/lib/python2.7/site-packages删除（ls | grep setup）所有文件和文件夹。

然后，我使用python.org（> curl https://bootstrap.pypa.io/ez_setup.py -o - | python）中的curl指示安装了setuptools，此后它对我来说很好用。
