python - pip : was OK for months now :ImportError: No module named 'pip._vendor.requests.adapters'

Question

到目前为止一切正常；使用 Win10、Anaconda 分发版，尝试运行 pip 会导致:

  File "C:\Users\Tim\Anaconda3\Scripts\pip-script.py",
  line    from pip import main

自从我昨天升级了一些软件包后就发生了这种情况。然后我无法运行 pip。

我最终做了一个全新安装的 anaconda。那解决了问题。
