我已经将我的应用程序版本部署到GAE，但现在我无法部署更新的版本。
当我尝试gcloud app deploy --version=VERSION时，我收到一堆错误，显示远程构建无法找到我的导入包：
Beginning deployment of service [default]...

我已经尝试了一些适当设置GOPATH的建议，包括以root身份运行命令，sudo -E和设置系统范围的GOPATH，到目前为止没有运气。无论是在Cloud Shell中部署还是在本地设置中运行命令，我都会遇到相同的错误集。如果我在进入远程构建阶段之前设置了错误的GOPATH构建失败。我没有改变第一次部署的源代码结构。
我花了很多时间在这上面，并感谢任何帮助或建议。 感谢。
修改 这是我的app.yaml
runtime: go
env: flex
api_version: go1
env_variables:
APP_DATABASE_CONFIG: "{...}"
APP_CONFIG: "{...}"
同时运行dev_appserver.py app.yaml我得到以下输出：
dev_appserver.py app.yaml

除了开头的警告外，它通常可以正常工作。我不知道为什么它会在我的app.yaml配置中发出警告，但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），我之后删除了该实例。
我想知道远程端的那些GOROOT（/ usr / local / go /）和GOPATH（/ workspace / _gopath /）来自哪里？这些是默认设置吗？此外，如果它有帮助，错误消息中显示的那些db和config包是我的，它们在project-root / src下。
app.yaml位于project-root / src / web下。我的GOPATH设置为project-root。我的GOROOT是空的。
