gopls: no metadata import error

[NilsJPWerner]

I am using the latest version of gopls in vscode. On this import:

import . "github.com/onsi/gomega/gstruct" 

I get the error: `could not import github.com/onsi/gomega/gstruct (no metadata for github.com/onsi/gomega/gstruct) LSP` Importing the parent package works fine

import . "github.com/onsi/gomega" 

### What version of Go are you using (`go version`)?

$ go version
go version go1.12.1 darwin/amd64
$ gopls version

Does this issue persist or does it resolve itself after some amount of time?

[stamblerre]

I'm able to import this package without problems - can you share your gopls logs for this error? They can be found by going to "View: Debug Console" -> "Output" -> "Tasks" -> "gopls".

[jiyeyuran]

I got the same problem. I already checked Use Language Server. The VSCode shows the tip as below even though I added the package in go.mod file.
could not import github.com/stretchr/testify/mock (no metadata for github.com/stretchr/testify/mock) LSP
Does LSP need to access Google Server which may not available in some countries?

[stamblerre]

@jiyeyuran: No, gopls should work fine in all countries. Can you confirm that this code compiles?

[DavidGamba]

I run into this issue all the time, I have to close the editor and re-open it (don't know how to reload the LSP server any other way) and it will basically go away until I do the next import in which case it will do it again.

I am using neovim with autozimu/LanguageClient-neovim.

[NilsJPWerner]

After I restart the error will disappear, and then reappear later.

[jiyeyuran]

@stamblerre The code can compile normally. The problem also happens on std library. The error disappear after I restart.

[mgxian]

I got the same problem when I use vscode-go

functions in strings can autocomplete, functions in net/http not working at all. It looks like sub-package can not imported.

[stamblerre]

@NilsJPWerner: And the error reappears even if you have not just added the imports? That is, you've had the same import in your file for a while and then the error comes back?

Can the other people who are experiencing this error also attach their logs?

[andreis]

Same exact problem here. killall gopls fixed it for me 😒

[stamblerre]

Thanks for the reports. I think the issue is that we don't re-run go/packages.Load if an import has gone from unresolved to resolved, only if the list of imports has changed. I will aim to have a fix ASAP.

[gopherbot]

Change https://golang.org/cl/180537 mentions this issue: internal/lsp: track missing imports, re-running packages.Load

[mgxian]

Does this issue fixed? With this bug I can not use vscode write go any more! I feel so bad!

[agnivade]

@mgxian - Please be patient. The issue will be closed when this is fixed.

[stamblerre]

@mgxian: You can also disable the language server by go.useLanguageServer: false. In the case of your error message, could you provide some additional logs? It seems like the error in your screenshots don't actually correspond to the errors in the logs.

[mgxian]

This is my test code, when I import package "fmt". I got the follow error.

This is my gopls log

When I reload the vscode window, the error disappear.

Every time I import a new package, The error will appear, and autocomplete is not work on the new package, When I reload the vscode window the error disappear and autocomplete work well. So what I should do to avoid this.

[stamblerre]

The CL I submitted above should address this problem. Can you sync to the latest gopls and see if it helps?

[gopherbot]

Change https://golang.org/cl/181578 mentions this issue: internal/lsp: fix check for changed imports

[mgxian]

Thanks @stamblerre It works !

[thepudds]

It seems the latest version of gopls resolved at least some of the problems for at least some of the people who reported issues here.

Is there anyone who reported a problem above that is still seeing the same problem with the latest version of gopls?

If you are still seeing the same problem , would you be able to supply the logs and other diagnostic information suggested in the troubleshooting section here:

https://github.com/golang/go/wiki/gopls

[DavidGamba]

The issue no longer shows with this fix for me. Thanks! :+1:
