Any clues on this lint issue "could not load export data: no export data for" ?

[zzxwill]

In a Github CI build, I hit the issue of golangci-lint. I've searched a lot but failed to find any clues. Please help take a look at it. Any directions would be appreciated. Thanks.

More detailed log is at https://github.com/oam-dev/kubevela/pull/1519/checks?check_run_id=2387867954

missing go.sum entry for module providing package gopkg.in/inf.v0

I think you have to run go mod tidy

[zzxwill]

@ldez That might be the root cause. The previous clue you shed on is go version. I changed to go 1.16, run 'golangci-lint', changed it back and ran go mod tidy. go.sum changed.

Let's push the updated go.sum and made another shot. Thanks.

[zzxwill]

Bingo, you are right! Thanks a lot.

[ohmpatel1997]

it does not work for me. I did clean the cache re downloaded dependencies, no changes in go.sum file. it gives me error importing the project path itself. ex: could not import imploy/user/user (-: could not load export data: no export data for "imploy/user/user") (typecheck).
imploy is the name of the project.

[tzabbi]

any news? same for me

EDIT:
I use the super-linter in github actions I encouter this issue.

[cjlapao]

I had this problem when my code was inside a folder like for example ./src, the solution was to add the go.work in the root and add the use ./src/

this will then make the super-linter work fine with no errors

[jwalton]

If you're finding this issue from a search in 2022; if you replace an interface{} with an any in a .go file, and forget to update your go.mod to 1.18, you'll also run into this problem.

[xrstf]

For me it was caused by a compilation error. We tried to update Cilium in a project with Kubernetes 1.24 and Cilium doesn't compile yet with k8s 1.24 (see cilium/cilium#19545). While golangci-lint only reported

can't run linter goanalysis_metalinter: buildir: failed to load package v1: could not load export data: no export data for "github.com/cilium/cilium/pkg/k8s/slim/k8s/apis/meta/v1"

Running staticcheck standalone gave more insights:

../../../pkg/mod/github.com/cilium/[email protected]/pkg/k8s/slim/k8s/apis/meta/v1/meta.go:36:63: cannot use obj (variable of type *ObjectMeta) as "k8s.io/apimachinery/pkg/apis/meta/v1".Object value in return statement: *ObjectMeta does not implement "k8s.io/apimachinery/pkg/apis/meta/v1".Object (missing method GetZZZ_DeprecatedClusterName) (compile)

[popescu-af]

This helped me confirm the problem was in one of the dependencies, thx. Linting worked after updating the dependency.

[miparnisari]

1. Ensure you are setting up the Go environment using actions/setup-go before running the golangci-lint action.
2. Use the mod=readonly option so that golangci-lint doesn't attempt to go mod tidy before running the analysis.

[harveysanders]

Apologies if this is an obvious question, but I'm not sure where to set mod=readonly. Would this be enabled by setting run.modules-download-mode to "readonly"?

I have tried that in my configuration file,

.golangci.toml

  [run]
  # If set we pass it to "go list -mod={option}". From "go help modules":
  # If invoked with -mod=readonly, the go command is disallowed from the implicit
  # automatic updating of go.mod described above. Instead, it fails when any changes
  # to go.mod are needed. This setting is most useful to check that go.mod does
  # not need updates, such as in a continuous integration and testing system.
  # If invoked with -mod=vendor, the go command assumes that the vendor
  # directory holds the correct copies of dependencies and ignores
  # the dependency descriptions in go.mod.
  #
  # Allowed values: readonly|vendor|mod
  # By default, it isn't set.
  modules-download-mode = "readonly"

but I'm still getting this error:

run golangci-lint
  Running [/home/runner/golangci-lint-1.51.0-linux-amd64/golangci-lint run --out-format=github-actions] in [] ...

  Error: golangci-lint exit with code 3

I've also tried to clean my modcache and run go mod tidy again. No luck.
Any ideas anyone?

[h4yfans]

This config solved my problem.

jobs:
  golangci:
    name: golangci
    runs-on: ubuntu-latest
    steps:
      - name: Install Go
        uses: actions/setup-go@v3
        with:
          go-version: 1.18
      - name: Checkout code
        uses: actions/checkout@v3
        with:
          persist-credentials: false
      - name: Run golangci-lint
        uses: golangci/[email protected]
        with:
          version: v1.48.0
          skip-cache: true
          args: --fix

[ldez]

using args: --fix is a bad idea because you will hide some problems.

[h4yfans]

I see, thanks. Do you have any suggestions for the problem?

[praneetloke]

I've been stumped by this issue for quite a while now. I've tried running tidy and changed Go versions but can't seem to nail down the cause. Does anyone have any other suggestions to help debug this issue?

level=warning msg="[runner] Can't run linter goanalysis_metalinter: inspect: failed to load package : could not load export data: no export data for \"github.com/cloudy-sky-software/pulschema/pkg\""
level=error msg="Running error: 1 error occurred:\n\t* can't run linter goanalysis_metalinter: inspect: failed to load package : could not load export data: no export data for \"github.com/cloudy-sky-software/pulschema/pkg\"\n\n"

[praneetloke]

I don't believe this. It was because I had a private Go module for which I had this in my CI pipeline:

git config --local url."https://praneetloke:${GH_REPO_PAT}@github.com/".insteadOf "https://github.com/"

instead I changed --local to --global:

git config --global url."https://praneetloke:${GH_REPO_PAT}@github.com/".insteadOf "https://github.com/"

Now golangci-lint passes in CI too.

[petar-dochev-f3]

In my case the reason was some patterns in .gitignore excluded some files under vendor. Then CI failed because those files were missing. Still it worked locally.

[matlle]

Same for me

[liuzhaomax]

看这里，这个留言可以解决问题。 You are my hero.

[EtienneM]

Oh boy, that was my issue, thanks a lot!

[nawa]

Spent 3 hours to find this myself. And after that I see your comment

It is so facepalmed sort of issue, very funny

[lizzy-0323]

Thanks a lot.

[janisz]

I have this problem as well on dependabot update. go mod tidy does not solve the problem as it's in internal pacakge

pkg/search/postgres/query/test/index_test.go:21:10: could not import github.com/stackrox/rox/tools/generate-helpers/pg-table-bindings/test/postgres (-: could not load export data: no export data for "github.com/stackrox/rox/tools/generate-helpers/pg-table-bindings/test/postgres") (typecheck)

https://github.com/stackrox/stackrox/actions/runs/4205140774/jobs/7296796512#step:10:161

[Sggoodman]

I found out that the problem was caused by the source I imported... Looks like we still need to check the source

[renevall]

In my case I forgot to set the repo variables that the actions uses to connect to private repos.

[CoolGoose]

In my case it was a PEBKC , i copy pasted the example action, which still pointed to go 1.17 🤦

[humvic]

In my case it was because of a version mismatch:

    github.com/pulumi/pulumi/pkg/v3 v3.55.0
    github.com/pulumi/pulumi/sdk/v3 v3.77.1

pkg/v3 depends on sdk/v3 and go mod tidy didn't handle the mismatch for some reason.

[alok87]

Delete and re-create go.mod and sum

[jmacd]

Probably only need to delete go.sum and re-run go mod tidy.

[MUCZ]

In my case, the issue arose because my Go 1.17 project imported a Go 1.18 library that utilizes any and generics. Although I was able to build the binary, I encountered this error when using golangci-lint. I resolved this by rewriting the library using Go 1.17.

[Semooze]

I run to the same problem with different package

it looks like this error is general error that involves with the module in the error message

In my cases, Go compiler cannot pull module from private repository.
Another case it's because the package need new version of go

[shubhag]

Updating go version from 1.20 to 1.21 fixed the issue for me

[arshamalh]

Exactly 👍🏼
It's about the Golang version AND dependencies in your project (they should match)
In my case, I was importing otel/attributes and it had a recent change importing a "cmp" package, recently added to Golang std-lib.
open-telemetry/opentelemetry-go@1fe2f03

Upgrading the version to 1.22.2 fixed the issue.

[nawa]

It is possible that your dependency package lost some its dependency somehow.

Real example: recently I observed this in vendored mode when you perform go mod vendor, push vendor folder to the origin and have modules-download-mode: vendor in golangci config. Turned out that my .gitignore is incorrect and ignores deeply nested folder inside vendor that makes it impossible to "compile" the dependency pointed in the error after "could not load export data: no export data for". If everything works locally and doesn't remotely on CI, check your .gitignore

[xieyuschen]

I would like to note that please ensure your program could be build by go build.

In my case, i import a library requires go1.18 but i use go1.17 to build, which will fail of course. The error message of goanalysis_metalinter doesn't reveal such kind of error.

[alok87]

any updates on this issue? any one built something for it?
