使用 gitbash 工具的 GKE 集群

Question

我的 python3.7 安装在 windows 的以下路径上 - C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Python 3.7

我正在尝试使用 GitBash 连接 GCP GKE 集群，当我在 gcloud 命令下运行连接 GKE 集群时，我收到 python 未找到错误。

$ gcloud container clusters get-credentials appcluster --region us-east4 --project dev /c/Users/surendar/AppData/Local/Google/Cloud SDK/google-cloud-sdk/bin/gcloud：第 181 行：exec：python：未找到

有什么解决错误的建议吗？

下面是Google/CloudSDK/google-cloud-sdk/bin/gcloud文件

181 行指向下面的声明，这是文件的最后一行

您需要将环境变量 CLOUDSDK_PYTHON 指向您的 Python 可执行文件（例如 python.exe）。要找到 Python 可执行文件，您应该可以在开始菜单中右键单击“Python 3.7”并查看“目标”。

在我的例子中，Python 可执行文件位于 C:\Users\g_r_s\AppData\Local\Programs\Python\Python37\python.exe

使用GitBash，您可以导出CLOUDSDK_PYTHON

$ export CLOUDSDK_PYTHON=/c/Users/g_r_s/AppData/Local/Programs/Python/Python37/python.exe
$ gcloud version
Google Cloud SDK 344.0.0
beta 2021.06.04
bq 2.0.69
core 2021.06.04
gsutil 4.62

注意：您也可以在 Windows 上安装 SDK 时尝试安装捆绑的 Python。
