在App Engine Standard上进行销售

Question

I know this topic has been referenced a few times already. Unfortunately I still wasn't able to find a working solution for my use case.

I can't seem to get vendoring working for my Go application on App Engine Standard. I'm using dep for vendoring.

I'm building a GraphQL API and here is my folder structure:

/GOPATH
└──/src
   └──/acme
      ├──/app
      |   ├── app.yaml
      |   └── app.go
      ├──/src
      |   ├── /mutations/
      |   ├── /queries/
      |   └── /types/
      └──/vendor/

Running goapp serve app/app.yaml on Cloud Shell fails with

        /home/xxx/gopath/src/acme/vendor/context (vendor tree)
        /google/go_appengine/goroot/src/context (from $GOROOT)
        /home/xxx/gopath/src/context (from $GOPATH)
        /google/gopath/src/context

Looks like the problem might be that one vendor is not using a full dependency name for "context". (EDIT: probably not the case though since I’m using 1.8)

Has anyone ever managed to successfully deploy on App Engine Standard using vendoring? Been pulling my hair all day on this.

Answer 1

The context package will be inside $GOROOT ( not in vendor directory ). Probably your Go Appengine SDK is old and does not support Go 1.8.

Update your SDK to the latest version. The $GOROOT should be like /path/to/somewhere/goroot-1.8
