Why is the goapp test looking for files in / tmp?

Question

I am trying to get tests running on my local machine for developers. Cloud SDK Version: 159.0.0

All I read says that I should not change GOROOT, so I'm not sure how to fix it.

$ / Users / bryan / google-cloud-sdk / platform / google_appengine / goroot / bin / goapp test

go: cannot find GOROOT directory: /tmp/go_sdk887571938/appengine/go_appengine/goroot

Having looked at the line main.go 155, where, it seems to me, an error occurs, I don’t see where "goroot" is installed.

 if fi, err := os.Stat(goroot); err != nil || !fi.IsDir() { fmt.Fprintf(os.Stderr, "go: cannot find GOROOT directory: %v\n", goroot) os.Exit(2) } 

Answer 1

You can try and follow the recommendation of this answer :

If your installation is confused no difference (with me once), just remove the cloud SDK and any links to it in $PATH . Also completely uninstall the normal Go installation.

Then start from scratch. Install Go, unzip google-cloud-sdk , run the installer (if necessary add to $PATH ), gcloud components install app-engine-go .
Voila.

As mentioned in the same answer, you do not install GOROOT anywhere, it is installed for you .

Answer 2

You might want to read how run / test works. The program is mainly embedded in a temporary place and then launched, so there may be a reason why it complains about your goroot.

Answer 3

I believe that you are causing the wrong goapp. You should call the one that is directly in the google_appengine folder as follows:

 /Users/bryan/google-cloud-sdk/platform/google_appengine/goapp test 

If you do not have goapp in google_appengine for some reason, I will be very surprised, but the following should work. (However, this is the correct way to call it. Goapp resolves the appengine goroot as a relative path from its own location, so it is important where the goapp itself is located.)

 GOROOT=/Users/bryan/google-cloud-sdk/platform/google_appengine/goroot /Users/bryan/google-cloud-sdk/platform/google_appengine/goapp test
