PIP卸载没有完全删除包

Question

长话短说，当我导入matplotlib时，numpy给了我一个错误，所以我想安装pip uninstall numpy并重新安装它。但未能完全卸载numpy.

RuntimeError                              Traceback (most recent call last)
RuntimeError: module compiled against API version 0xe but this version of numpy is 0xd

我决定卸载和重新安装后，发现解决方案在网上不工作。(ImportError: numpy.core.multiarray failed to import)

pi@raspberrypi:~ $ pip uninstall numpy
Uninstalling numpy-1.16.6:
Would remove:
/home/pi/.local/bin/f2py
/home/pi/.local/bin/f2py2
/home/pi/.local/bin/f2py2.7
/home/pi/.local/lib/python2.7/site-packages/numpy-1.16.6.dist-info/*
/home/pi/.local/lib/python2.7/site-packages/numpy/*
Proceed (y/n)? y
Successfully uninstalled numpy-1.16.6
pi@raspberrypi:~ $ pip install numpy
Looking in indexes: https://pypi.org/simple, https://www.piwheels.org/simple
Requirement already satisfied: numpy in /usr/lib/python2.7/dist-packages (1.16.2)

假设第一个命令已经卸载了numpy，为什么需求已经满足了?我尝试了pip uninstall和pip3 uninstall。然后也进入python和python3导入模块，再次检查模块是否还安装。模块导入成功。同样在/usr/lib/python2.7/dist-packages文件夹中，numpy仍然在那里。有什么问题吗?如何成功卸载和重新安装numpy?

编辑:我手动进入所有版本python的dist-packages目录，rm所有numpy相关文件。然后重新安装。

您可以使用以下命令删除文件

rm -rf f2py
rm -rf 2py2
rm -rf numpy-1.16.6.dist-info/*
rm -rf numpy/*

或只有:

rm  f2py
rm  2py2
rm  numpy-1.16.6.dist-info/*
rm  numpy/*
