hyangah commented 2 years ago

Can you run "Go: Locate Configured Go Tools" command and check if the extension chose the right go version (1.18)?

go chosen from the terminal may be different from the go used by the extension depending on how your login shell is configured or how the vscode program was launched.

Thanks. @xiazemin Did you update your go.mod file to use go1.18 language feature? gopls side work to offer a quickfix to recommend the right language version when it sees the new language feature (https://github.com/golang/go/issues/51086) is in progress.

If that's the cause of the issue, run go mod edit -go 1.18 Otherwise, we need a reproducer example.

xiazemin commented 2 years ago

after I use
Go: Restart Language Server Restart the running instance of the language server

it works for me

hyangah commented 2 years ago

@xiazemin I am confused. Can you clarify if the issue was due to the go version statement in go.mod, or due to a non-deterministic bug that's somehow cleared up by restarting a gopls (without any code/go.mod change)?

hyangah commented 2 years ago

Thanks.

I guess some transient version mismatch made gopls to report the issue, but, unfortunately, I don't see a path to investigate further without an example to reproduce the problem. Closing.

Shawn-Huang-Tron commented 1 year ago

I have met this issue too, but i solved it by upgrade my gopls version to the latest.Hope that will help the other people who have met the same problem.
