pip uninstall 不会完全删除包

Question

长话短说，当我导入 matplotlib 时，numpy 给了我错误，所以我想 pip uninstall numpy 并重新安装它。但无法完全卸载 numpy。

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

ImportError: numpy.core.multiarray failed to import

网上查的解决办法都不行，决定卸载重装。 (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，为什么要求已经满足了？ pip uninstall 和 pip3 uninstall 我都试过了。然后还进入 python 和 python3 导入模块作为双重检查以查看模块是否仍然安装。模块导入成功。同样在 /usr/lib/python2.7/dist-packages 文件夹中，numpy 仍然存在。问题是什么？如何成功卸载并重新安装 numpy？

编辑：我手动进入了python所有版本的dist-packages目录，以及rm所有与numpy相关的文件。然后重新安装工作。

Answer 1

您可以使用此命令删除文件

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

或仅：

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

pip uninstall 不会完全删除包

pip uninstall does not remove package fully
