python-3.x - FileNotFoundError：[Errno 2] 没有这样的文件或目录：'/Users/x/anaconda3/lib/python3.6/site-packages/numpy-1.19.4.dist-info/RECORD'

问题描述

我正在尝试在 Mac OS 下numpy使用命令卸载pip3 uninstall numpy，但它会引发错误：

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

FileNotFoundError: [Errno 2] No such file or directory: '/Users/x/anaconda3/lib/python3.6/site-packages/numpy-1.19.4.dist-info/RECORD'

检查版本numpy：

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
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy as np
>>> np.__version__
'1.18.0'

有人可以帮助解决这个问题吗？谢谢。

解决方案

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

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

问题发生的原因是RECORD文件METADATA不可用于numpy-1.19.4.dist-info. 所以我从 复制它们numpy-1.18.0.dist-info，问题解决了。
