長話短說，numpy 在我匯入 matplotlib 時給了我錯誤，所以我想pip uninstall numpy重新安裝它。但未能完全卸載 numpy。

ImportError: numpy.core.multiarray failed to import
在網上找到的解決方案不起作用后，我決定卸載并重新安裝。（匯入錯誤：numpy.core.multiarray 匯入失敗）
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)
假設第一個命令已經卸載了numpy，為什么要求已經滿足？我嘗試了pip uninstall和pip3 uninstall。然后也進入python并python3匯入模塊作為仔細檢查以查看模塊是否仍然安裝。并且模塊匯入成功。也在/usr/lib/python2.7/dist-packages檔案夾里，numpy還在那里。問題是什么？如何成功卸載并重新安裝numpy？
Edit: I manually went into the dist-packages directory of all versions of python, and rm all the numpy related files. then reinstallation works.
uj5u.com熱心網友回復：
您可以使用此命令洗掉檔案
rm -rf f2py
rm -rf 2py2
rm -rf numpy-1.16.6.dist-info/*
rm -rf numpy/*
或僅：
rm f2py
rm 2py2
rm numpy-1.16.6.dist-info/*
rm numpy/*
