运行python安装包没找到

一、错误信息

ImportError: dlopen(/Users/menghuiding/Library/Python/3.8/lib/python/site-packages/PIL/_imaging.cpython-38-darwin.so, 0x0002): tried: 
'/Users/menghuiding/Library/Python/3.8/lib/python/site-packages/PIL/_imaging.cpython-
38-darwin.so' (mach-o file, but is an incompatible architecture (have 'arm64', need 'x86_64')), 
'/System/Volumes/Preboot/Cryptexes/OS/Users/menghuiding/Library/Python/3.8/lib/python/site-packages/PIL/_imaging.cpython-38-darwin.so' (no such file), 
'/Users/menghuiding/Library/Python/3.8/lib/python/site-packages/PIL/_imaging.cpython-38-darwin.so' (mach-o file, but is an incompatible architecture (have 'arm64', need 'x86_64'))

二、原因

python安装错位置，调用不到，则需要重新安装

三、解决方案

找到python安装位置，python版本上面报错有

root@MacBook-Pro%  which python3.8
/Library/Frameworks/Python.framework/Versions/3.8/bin/python3.8

安装

sudo /Library/Frameworks/Python.framework/Versions/3.8/bin/python3.8
-m pip install --force-reinstall matplotlib

安装成功
