Xcode 更新破坏了 gcloud 和 gsutil

Question

几个小时前，我Xcode更新到最新版本，造成gcloud和gsutil命令停止工作。例如，在更新完成前一分钟，该命令gsutil -m rsync运行良好。

在写这个问题时，我注意到我不再git工作了。

由于我不是 Python 人，有人可以向我解释现在到底发生了什么吗？我很想得到一些帮助。

python -V输出是Python 2.7.16。

python3 -V输出是Python 3.9.0。

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

pip3 -V 输出是 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：

这就是我得到的gsutil help：

所以几乎每天没事后，我发现了一个解决方案：什么我需要做的是设置名为环境变量CLOUDSDK_PYTHON来/usr/bin/python。

我编辑了我的.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，所以如果有人愿意花时间解释一下，我会很高兴的。
