Question

我试图在Mac操作系统下使用命令pip3 uninstall numpy卸载numpy，但它引发了错误：

x@bogon ~ % pip3 uninstall numpy
Found existing installation: numpy 1.19.4
ERROR: Exception:

检查numpy:的版本

x@bogon ~ % python3
Python 3.6.7 |Anaconda custom (x86_64)| (default, Oct 23 2018, 14:01:38) 
[GCC 4.2.1 Compatible Clang 4.0.1 (tags/RELEASE_401/final)] on darwin

>>> import numpy as np
>>> np.__version__
'1.18.0'

有人可以帮助解决这个问题吗？谢谢

Answer 1

/Users/x/anaconda3/lib/python3.6/site-packages:中有多个版本的Numpy

numpy
numpy-1.14.3.dist-info
numpy-1.18.0.dist-info
numpy-1.19.4.dist-info

出现此问题的原因是RECORD和METADATA文件不可用于numpy-1.19.4.dist-info。所以我从numpy-1.18.0.dist-info复制了它们，问题解决了。
