unexpected module path "golang.org/x/lint" using go.mod - no problems using otherwise

[adriendomoison]

Running go version go1.12.1 darwin/amd64 on MacOS 10.14.2

I'm trying to install grpc using go.mod but I get stuck on the lint package

go: github.com/golang/[email protected]: parsing go.mod: unexpected module path "golang.org/x/lint"
go get: error loading module requirements

Here is the full install

go: github.com/golang/[email protected]: parsing go.mod: unexpected module path "golang.org/x/lint"
go get: error loading module requirements

The package itself fails alone:

$ go get github.com/golang/lint
go: finding github.com/golang/lint latest
go: github.com/golang/[email protected]: parsing go.mod: unexpected module path "golang.org/x/lint"
go: error loading module requirements

I don't have the issue if I run it outside of my repository with go.mod

$> go get -u google.golang.org/grpc
$>

Any ideas?

This problem has been fixed in 7c93bdf. You just have to wait for the next version to be released.

Edit: It hasn't been fixed.

Relevant issues:

• Error when updating the library with go modules googleapis/google-cloud-go#1359
• go.mod: update dependencies googleapis/google-api-go-client#342
• cmd/go: "get -u" stumbles over repos imported via non-canonical paths golang/go#30831

[adriendomoison]

Sorry, the titles were very different. So what can we do in the meantime? Any workaround or waiting is the only option if we want to use go.mod? Any ETA? Thanks!

@adriendomoison

Here's a workaround for you: run go get google.golang.org/[email protected] for the time being.

It should be noted, your go get -u google.golang.org/grpc's -u will lead the Go modules to try to update all related dependencies (not just grpc/grpc-go).

[menghanl]

Note that release 1.19.1 doesn't have the fix (7c93bdf) that @aofei mentioned.

If I understand correctly, the fix is actually 6572a80, which was in 1.17.0.
The problem is that, all packages that depend on gRPC need to upgrade gRPC past 1.17.0, so go mod won't see the wrong package (golang/lint).

[adriendomoison]

Thanks! It looks like the transition to go.mod for the go community, in general, is not going to be easy... 😬

[dfawley]

I don't think there's anything we can do for this, unfortunately.

[jeanbza]

For anyone still running into this problem - this has been fixed. For whichever you depend on, please use:

• cloud.google.com/go v0.37.4
• google.golang.org/api v0.3.2
• go.opencensus.io v0.20.1
