有什么方法可以修复mac上的azure cli import pyparsing错误吗

Question

重新安装azure CLI后，我正在尝试运行它，我得到了：

$ az
Traceback (most recent call last):

ImportError: The 'pyparsing' package is required; normally this is bundled with this package so if you get this warning, consult the packager of your distribution.

我检查了python二进制路径，发现我已经有了这个包。

发现问题。pyparsing包中调用的一个子包被调用到具有相同名称的本地文件夹脚本。结果导入失败。

$ /usr/local/Cellar/azure-cli/2.25.0/libexec/bin/python
Python 3.8.11 (default, Jun 29 2021, 03:08:07)
[Clang 12.0.5 (clang-1205.0.22.9)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import pyparsing
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/Cellar/azure-cli/2.25.0/libexec/lib/python3.8/site-packages/pyparsing.py", line 104, in <module>
import copy
File "/Users/shprayev/copy.py", line 4, in <module>
from pymongo import MongoClient
ModuleNotFoundError: No module named 'pymongo'

所以pyparsing导入了copy，我的路径中有copy.py。重命名脚本后，它工作
