我已经将应用程序的一个版本部署到GAE，但是现在我无法部署一个较新的版本。当我尝试时gcloud app deploy --version=VERSION，出现一堆错误，表明远程版本找不到我的导入包：

我已经尝试过一些对GOPATH进行正确设置的建议，包括以root身份运行命令，sudo
-E以及设置系统范围的GOPATH，到目前为止还算不错。无论我部署在Cloud
Shell中还是在本地设置中运行命令，我都会遇到相同的错误集。如果我设置了错误的GOPATH，则在进入远程构建阶段之前，构建会失败。我也没有从第一次部署中更改源代码结构。

我花了很多时间在此上，并感谢任何帮助或建议。谢谢。

编辑： 这是我的app.yaml

runtime: go
env: flex
api_version: go1

env_variables:
   APP_DATABASE_CONFIG: "{...}"
   APP_CONFIG: "{...}"

同样运行，dev_appserver.py app.yaml我得到以下输出：dev_appserver.py app.yaml

除了开头的警告之外，它通常可以正常工作。尽管配置了app.yaml，但我不知道为什么它会发出警告，但是如果它帮助我部署的第一个实例是一个标准项目（Google演示项目），后来又删除了该实例。

我想知道远端的那些GOROOT（/ usr / local / go /）和GOPATH（/ workspace / _gopath
/）来自何处？这些是默认设置吗？同样，如果有帮助，错误消息中显示的那些db和config软件包是我的，它们位于project-root / src下。

app.yaml位于project-root / src / web下。我的GOPATH设置为项目根目录。我的GOROOT是空的。
