golang.org/x/sys and other packages don't seem to work #18

floren · 2020-04-23T22:48:53Z

I'm walking through the dependencies in my go.mod and I find that the golang.org/x/ repositories give me trouble:

% go-licenses csv golang.org/x/sys
Error: errors for ["golang.org/x/sys"]:
golang.org/x/sys: -: module golang.org/x/sys@latest found (v0.0.0-20200420163511-1957bb5e6d1f), but does not contain package golang.org/x/sys

Is there a trick to this? Advice?

Can you provide a copy of your go.mod file please?

spatecon · 2020-05-28T13:52:46Z

The same with:

github.com/oklog/oklog
google.golang.org/genproto
golang.org/x/crypto

and others.

RJPercival · 2020-05-28T14:51:13Z

@ilya310300 @floren Please provide a copy of your go.mod file or link to a repo.

sebd71 · 2020-06-01T16:02:54Z

I'm not fully sure that it's the right way to fix that but adding "golang.org": "blob/master/", in repoPathPrefixes definition (file library.go) seems fix the problem :

var (
	// TODO(RJPercival): Support replacing "master" with Go Module version
	repoPathPrefixes = map[string]string{
		"github.com":    "blob/master/",
		"bitbucket.org": "src/master/",
		"golang.org":    "blob/master/",
	}
)

@RJPercival : would you please confirm if it's right way to fix that issue ?

floren · 2020-06-01T16:08:15Z

If you drop the contents of this gist into a directory, you can 'go build' and it'll work, but running go-licenses csv golang.org/x/sys will fail as mentioned above.

This is a general problem with the sys package. For example. the following fails: https://play.golang.org/p/saGt7CYOsm4

package main

import (
	"golang.org/x/sys"
)

func main() {
}

Here is a repo showing this problem: https://github.com/dcormier/go-licenses (complete with the requested go.mod file)

Im not sure if this is the same problem but

import (
	"golang.org/x/sys/windows/registry"
)

PS D:\Unity_Projects\nwt7-lvl5-castles\windows\services\go_http_web_service> go build .\http.go
http.go:24:2: no required module provides package golang.org/x/sys/windows/registry: go.mod file not found in current directory or any parent directory; see 'go help modules'

Bobgy · 2021-07-31T12:38:28Z

I think the root cause is that golang.org/x/sys is a module, but it is not a package.
Refer to its source code: https://cs.opensource.google/go/x/sys.
There are no go source files directly in this folder.

So we cannot load the package golang.org/x/sys.

Bobgy · 2021-07-31T12:39:27Z

This can be workarounded by my v2 implementation: #71 that works on modules directly instead of packages.

Bobgy · 2022-04-11T01:59:27Z

Please comment if this still persists, updated documentation and released go modules support in v1.1.0.

Note, go-licenses csv accepts a go package, a folder without go files is not a go package.

gennaro-tedesco · 2022-10-31T13:27:12Z

I am still seeing the problem:

no Go files in ~/go/src/golang.org/x/sys

what was the accepted solution/workaround? I see that #82 was merged though: is anyone else still experiencing the problem?

Bobgy · 2022-11-03T02:15:15Z

@gennaro-tedesco can you share detailed reproduction steps?

gennaro-tedesco · 2022-11-03T09:24:57Z

Sure: I am on macOS 10.16.0 Big Sur and I have tried with different values for the GO111MODULE env variable.

if installing via go install golang.org/x/sys@latest I get a combination of "no Go files in ~/go/src/golang.org/x/sys" and "module golang.org/x/sys@latest found (v0.1.0), but does not contain package golang.org/x/sys" according to whether or not I set GO111MODULE to explicit values.
if importing golang.org/x/sys in a module and running go mod tidy I get

../../go/pkg/mod/golang.org/x/sys@v0.0.0-20200918174421-af09f7315aff/unix/zsyscall_darwin_arm64.1_13.go:40:3: //go:linkname must refer to declared function or variable

The commands you ran do not relate to go licenses though.

Note golang.org/x/sys is not a go package, that's why those commands failed. There are go packages with golang.org/x/sys as prefix.
