在Google云端上运行node.js，但在docker上运行时出错

Question

我尝试了以下文档以在Google云上运行node.js应用程序：https : //cloud.google.com/nodejs/getting-started/hello-
world

Node.js运行正常，但是如果我运行，gcloud preview app run app.yaml我会…。

最新的Google Cloud SDK 0.9.65版本存在一个错误。

您可以使用以下命令还原到Cloud SDK 0.9.64：

gcloud config set component_manager/fixed_sdk_version 0.9.64
gcloud components update

下一个版本应具有此修复程序。

要返回到当前版本的SDK，请运行：

gcloud config unset --scope=installation component_manager/fixed_sdk_version
gcloud components update

SDK版本0.9.82的更新

Node.js应用程序不再需要Docker。如果不依赖于AppEngine特定的API，则在本地运行应用的首选方法是：

npm install
npm start

在您的app.yaml文件中包括以下内容：

runtime: nodejs
vm: true
api_version: 1
