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
.
