我刚刚从Fedora 32升级到Fedora 33（Python 3.9附带）。从那以后gcloud命令停止工作：
[guy@Gandalf32 ~]$ gcloud

来自GCP支持的更新
GCP支持提到，318.0.0发布的新版本2020.11.10应支持python 3.9
我将gcloud sdk更新到了318.0.0，现在看起来像支持python 3.9.0。
要解决此问题，请运行
gcloud components update
Fedora 33包含python 2.7，并且要强制GCloud SDK使用它，请设置此环境变量
export CLOUDSDK_PYTHON=python2
您可以将此导出命令添加到您的 ~/.bash_profile
Python 3.9非常新，并且预期Gcloud SDK不支持3.9，它是为与2.7.x和3.6-3.8兼容而编写的（3.8可能会引起一些兼容性问题，我建议使用3.7）
解决方法是，将Python 3.8或3.7（此版本适用于Gcloud和大多数Linux发行版）作为系统范围的解释器，并尝试使用gcloud命令。
