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

Question

我在重新安装后尝试运行 azure CLI：

$ az
Traceback (most recent call last):
  File "/usr/local/Cellar/python@3.8/3.8.11/Frameworks/Python.framework/Versions/3.8/lib/python3.8/runpy.py", line 185, in _run_module_as_main

    raise ImportError(
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 包中调用的子包之一被调用到同名的本地文件夹脚本。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 导入副本，我的路径中有 copy.py。 重命名脚本后它起作用了
