Xcode更新打破了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工作正常。

在写这个问题时，我注意到我不再有git工作。

既然我不是Python人，有人可以向我解释一下现在到底发生了什么吗？我希望得到一些帮助。

python -V输出Python 2.7.16。

python3 -V输出Python 3.9.0。

pip -V输出pip 20.2.3 from /Users/<MY_USER>/Library/Python/2.7/lib/python/site-packages/pip (python 2.7)

pip3 -V输出pip 20.2.3 from /Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/pip (python 3.9)

这就是我得到的gcloud help：

因此，在几乎一天一无所获之后，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。

我编辑了我的.zprofile并补充说：

export CLOUDSDK_PYTHON="/usr/bin/python"

我仍然不知道是什么原因造成的，所以如果有人愿意花时间，我会很高兴得到解释。
