Conda：Pip升级破坏了pip，如何在env中取回pip

Question

我用以下方法升级了pip：

> pip install --upgrade pip

Collecting pip

Installing collected packages: pip
  Found existing installation: pip 10.0.1
    Uninstalling pip-10.0.1:
Could not install packages due to an EnvironmentError: [Errno 39] Directory not empty: 'commands'

现在它正在使用/usr的系统点

如何在我的conda环境中找回pip？ （也许没有重新安装env）

我在激活环境后尝试过

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python get-pip.py

但那只是给出了同样的错误
