为什么不是'；t Gcloud安装"；app engine go“；组件？

我正在我的Macbook Pro osX 0.11.6上为应用程序引擎设置Golang： go版本go1.8达尔文/amd64

我用

sudo/usr/local/googlecloudsdk/bin/gcloud组件更新

使用sudo重新运行命令：sudo/usr/local/googlecloudsdk/bin/gcloud。。。

我被告知运行“sudo/usr/local/googlecloudsdk/bin/gcloud…”的命令是什么

为什么没有安装“app engine go”组件？

您可以通过运行

gcloud components list

默认情况下，许多组件都没有安装，其中有一些组件，有些组件相当大。如果未安装组件，则可以通过

gcloud components install app-engine-go

---

由于您已在计算机范围内安装了gcloud，因此需要使用

sudo

运行最后一个命令，谢谢您的帮助！你为我节省了很多时间。
