I read a lot of issues. There seems to be no solution?

What did you do?

This case from conditional-compilation-with-build-tags

What did you expect to see?

I hope to fix this error message when I used //go:build !alt

What did you see instead?

vscode error:

No packages found for open file /go/src/my-practice/my/foo_alt.go: <nil>. If this file contains build tags, try adding "-tags=<build tag>" to your gopls "buildFlags" configuration (see (https://github.com/golang/tools/blob/master/gopls/doc/settings.md#buildflags-string). Otherwise, see the troubleshooting guidelines for help investigating (https://github.com/golang/tools/blob/master/gopls/doc/troubleshooting.md).

That looks like tags working correctly

Unlike many projects, the Go project does not use GitHub Issues for general discussion or asking questions. GitHub Issues are used for tracking bugs and proposals only.

@wonderfate I'm not sure I understand your question: you set "-tags=alt" in your configuration, and are getting an error about not having any packages for a file tagged !alt. That looks like it is working as intended: your file is being excluded by your configuration.
