  • cannot import name 'main' 解决方案

    error description:

    pip3 install numpy
    Traceback (most recent call last):
      File "/usr/bin/pip3", line 9, in <module>
        from pip import main
    ImportError: cannot import name 'main'

    You must have inadvertently upgraded your system pip (probably through something like sudo pip install pip --upgrade)

    pip 10.x adjusts where its internals are situated. The pip3 command you're seeing is one provided by your package maintainer (presumably debian based here?) and is not a file managed by pip.

    You can read more about this on pip's issue tracker

    You'll probably want to not upgrade your system pip and instead use a virtualenv.

    To recover the pip3 binary you'll need to

     sudo python3 -m pip uninstall pip && sudo apt install python3-pip --reinstall

    If you want to continue in "unsupported territory" (upgrading a system package outside of the system package manager), you can probably get away with python3 -m pip ... instead of pip3.
