Answer 1

我将在这里添加对我有用的解决方案，以防有人无法使用上述方法解决他们的问题。打开Terminal或Command prompt或Anaconda prompt并按照 3 个步骤操作：

步骤 1
输入python -m pip uninstall pip

第2步
python -m ensurepip

第 3 步
python -m pip install -U pip

使用 .pip 可以轻松检查 pip 版本pip --version。希望这对你有用:)

Answer 2

1. 卸载当前点子:

   python -m pip uninstall pip setuptools
   

2. get-pip.py从https://bootstrap.pypa.io/get-pip.py下载

3. 执行get-pip脚本:

   python get-pip.py
   

Answer 3

这对我有用:

easy_install --upgrade pip

Windows 10,Python 3.6

Answer 4

尝试卸载pip并安装get-pip.py.它似乎是适用于Windows的3.6版本中的错误. https://github.com/pypa/pip/issues/3964
