cannot find module providing package

[qw1mb0]

What did you do?
I following the guide to add example-inc API, but got cannot find module providing package:

$ operator-sdk add api --api-version=app.example.com/v1alpha1 --kind=AppService

Usage:
  operator-sdk add api [flags]

Flags:
      --api-version string   Kubernetes APIVersion that has a format of $GROUP_NAME/$VERSION (e.g app.example.com/v1alpha1)
  -h, --help                 help for api
      --kind string          Kubernetes resource Kind name. (e.g AppService)

Global Flags:
      --verbose   Enable verbose loggin

What did you expect to see?
I pass without error

What did you see instead? Under which circumstances?
I use the operator-sdk v0.8.1 release and make install to build and install.

@qw1mb0 The error output is not very helpful unfortunately. Looking at the code, my guess would be that there was an error compiling the code generation binaries, which is the next step after creating the CRD.

The code I'm thinking is the culprit is here and here

Do you have any files in /home/user/go/src/github.com/example-inc/app-operator/build/_output/bin?

I also have similar issue. It was working last week, but today, when I tried to create a new operator, I got this following error (My OS is macOS Mojave ):

[mossuchida]

Well, in my case, my go.mod had the following:
github.com/peterbourgon/diskv v0.0.0-20190425080511-0be1b92a6df0
so, I changed it to
github.com/peterbourgon/diskv/v3 v3.0.0
Then I run
go mod vendor
this made me pass this part, but I have noticed bunch of stuffs are missing in vendor dir now (e.g. Error: chdir path-to/go/src/acmeair-operator/vendor/k8s.io/code-generator: no such file or directory)
I am not sure what is going wrong in my env right now..

[jonathanbeber]

@qw1mb0 can you run operator-sdk add api --api-version=app.example.com/v1alpha1 --kind=AppService with the --verbose flag:

operator-sdk --verbose add api --api-version=app.example.com/v1alpha1 --kind=AppService

I had problems with that, I resolved it setting the right value for GOROOT, but I'm not sure what's happening in your case. I suspect that you GOROOT should be pointing to /usr/lib/go-1.12/, not /usr/lib/go-1.12/bin, but the detailed output (verbose mode) would help.

[jonathanbeber]

You can try to update your go version to v1.12.5 as well

[estroz]

@qw1mb0 @mossuchida are you running operator-sdk add api/is your operator project in $GOPATH/src?

[mossuchida]

Yes, I am running the command in $GOPATH/src/app-operator dir. I have upgraded go version to v1.12.5, but still the same issue. Maybe I need to upgrade Operator SDK also? (Are there upgrade documentation?) . Currently, my version is operator-sdk version: v0.7.0

[estroz]

Try running the following:

$ mkdir -p pkg/apis/app && echo "package app" > pkg/apis/app/stub.go

To see if that gets rid of the first error.

I got this similar issue

[estroz]

@qw1mb0 @mossuchida have you tried the suggested fix?
@chinglinwen is this a persistent error? I was unable to reproduce it. Can you submit a separate issue with all the required information? Thanks!

[chinglinwen]

I just changed go.mod operator-sdk v0.8.x to operator-sdk v0.8.1 @estroz , it works now

[qw1mb0]

Hm.
After add --verbose flag all fine.

[mossuchida]

After upgrading to v0.8.1, It seems like it is working although I see some errors while creating. Is this expected?
