Gitlab CI和Go模块

I have a Go project and I want write a Gitlab CI file my project but I see error loading module requirements. This is my gitlab CI file:

stages:
  - compile
build:
  stage: compile
  image: golang:1.12
  script:
    - go build -o binary
error :

Be sure you upload the last go.sum file. Just before uploading to master for the ci execution run go get, upload to master and run the ci.

The primary error seems to be:

go: google.golang.org/appengine@v1.6.1: unrecognized import path
 "google.golang.org/appengine" (parse 
 https://google.golang.org/appengine?go-get=1: no go-import meta tags ())

I would try running go get -v google.golang.org/appengine and curl -v https://google.golang.org/appengine?go-get=1 from within your CI environment to see what they show.

This is what I get for go get -v google.golang.org/appengine:

$ go get -v google.golang.org/appengine
Fetching https://google.golang.org/appengine?go-get=1
Parsing meta tags from https://google.golang.org/appengine?go-get=1 (status code 200)

Perhaps you have some network connectivity, firewall, or HTTP proxy issue.
