python - Xcode更新中断了gcloud和gsutil

Question

几个小时前，我将Xcode更新到最新版本，这导致gcloud和gsutil命令停止工作。例如，在更新完成前一分钟，命令gsutil -m rsync运行正常。
在写这个问题时，我注意到我不再使用git了。
由于我不是Python专家，因此有人可以向我解释一下现在到底发生了什么吗？我希望有帮助。python -V输出为Python 2.7.16。python3 -V输出为Python 3.9.0。pip -V输出为pip 20.2.3 from /Users/<MY_USER>/Library/Python/2.7/lib/python/site-packages/pip (python 2.7)pip3 -V输出为pip 20.2.3 from /Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/pip (python 3.9)这是我得到gcloud help的结果:

    spec = importlib.util.find_spec('enum')
AttributeError: module 'importlib' has no attribute 'util'

这就是我得到的 gsutil help:

因此，经过将近一天的忙碌之后，我找到了一个解决方案:我需要做的是将一个名为CLOUDSDK_PYTHON的环境变量设置为/usr/bin/python。
我编辑了.zprofile并添加了:

export CLOUDSDK_PYTHON="/usr/bin/python"

我仍然不知道是什么原因造成的，因此，如果有人愿意花时间，我将很高兴为您提供解释。
