python - 属性错误 : module 'importlib' has no attribute 'util'

Question

我刚刚从 Fedora 32 升级到 Fedora 33(Python 3.9 附带)。从此gcloud命令停止工作:

[guy@Gandalf32 ~]$ gcloud 
Error processing line 3 of /home/guy/.local/lib/python3.9/site-packages/XStatic-1.0.2-py3.9-nspkg.pth:

GCP 支持更新
GCP support mentioned那个新版本318.0.0发布于 2020.11.10应该支持python 3.9
我将我的 gcloud sdk 更新为 318.0.0现在看起来支持 python 3.9.0。
要解决此问题，请运行gcloud components updateFedora 33 包含 python 2.7 并强制 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_profilePython 3.9 很新，预计 Gcloud SDK 不支持 3.9，它被编写为兼容 2.7.x & 3.6 - 3.8(3.8 会导致一些兼容性问题，我建议使用 3.7)
作为解决方法，将 Python 3.8 或 3.7(这些版本适用于 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。
