“使用”pip install virtualenv“时无法找到'pip._vendor.distlib'的查找程序错误

Question

我想在Windows 10下使用Python 3.6版本安装virtualenv。当我运行”pip install virtualenv“时得到这个错误。我是Python的新手。

Answer 1

尝试卸载pip并安装get-pip.py。它似乎是Windows 3.6版本中的一个错误。 https://github.com/pypa/pip/issues/3964

这里也有报道。 pip install jupyter: "Unable to locate finder for 'pip._vendor.distlib'"

Answer 2

1. 卸载当前画中画：

   python -m pip uninstall pip setuptools 
   

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

3. 执行得到点子的脚本：

   python get-pip.py 
   

Answer 3

这为我工作：

easy_install --upgrade pip

的Windows 10，Python的3.6
