/cc @matloob per owners.

I'm getting this with go-sumtype. It fails on a single main.go file:

package main

import (
	"errors"
)

func main() {
	_ = errors.New("x")
}

Then:

$ go-sumtype main.go
internal error: package "errors" without types was imported from "command-line-arguments"

@atombender, go-sumtype does fail when run on main.go, but it looks like that's due to it using an old version of golang.org/x/tools/go/packages. When its dependency on go/tools is updated in its go.mod file (I updated it to v0.0.0-20200423205358-59e73619c742) the error no longer occurs.

@mmcloughlin I'm wondering if you could give me more specific instructions for reproducing locally?

@matloob I'm not seeing this in the latest x/tools release. This can be closed as far as I'm concerned. Thanks!

Great, thanks! Will close this issue.

Just a quick comment in case someone else see this, though probably not super helpful...

Right now, I'm seeing a couple different flavors of this issue:

2021/12/12 21:03:14 internal error: package "errors" without types was imported from "golang.zx2c4.com/go118/netip"

and

2021/12/12 21:01:39 internal error: package "sort" without types was imported from "net"

Two possible correlating factors:

1. I am using tip (with a shortcut of export PATH=$(gotip env GOROOT)/bin:$PATH, version is go version devel go1.18-49b7c9c Sun Dec 12 16:09:13 2021 +0000 linux/amd64 )
2. I am juggling a bunch of nested modules with a series of replace directives. Some chance I have a mistake there, though I think I still see the error after removing the replace directives.

If I sort this out more, I will add more here, or open a new issue.

Updating to the golang.org/x/tools@latest (v0.1.8) and rebuilding my binary seems to have solved the issue.

That wasn't the first thing I tried because I was seeing the problem with a relatively recent version of x/tools:

golang.org/x/tools v0.1.7

So maybe something related to x/tools being recent, but too far behind tip?

(And perhaps similar to #49164, #49159, marwan-at-work/mod#9, and perhaps others as I google a bit more now).

@matloob I am going to re-open this issue so it at least pops up on your radar or in case something like a different error is useful, but please of course feel free to close if no action is warranted here.

Thanks, and sorry for the noise!

given the length of time passed, new issues should probably be filed as new issues.

In case someone has this issue nowadays..... update the deps!
go get -u ./...

sometimes, idk why, the go tools package is installed in a previous version.

Still seeing this issue after running go get -u ./...

I'm getting this issue now as well.
