What did you do?
When installing 1.19 go version & reinstall/update the additional go tools like gopls & dlv, I have an issue with delve and the package https://github.com/hashicorp/golang-lru/tree/master/simplelru. So, I can’t install delve. But if I use the 1.18.5 version of go, I have no issue and I can install the last delve version (1.9.0)
But if I use GODEBUG=goindex=0, it works 😃
Reproduce: I try to do a fresh install of go (with 1.19.0) and then, install delve.
- Install go:
rm -rf ${HOME}/bin/go
cd "$(mktemp -d)"
wget https://go.dev/dl/go1.19.linux-amd64.tar.gz
tar -C ${HOME}/bin -xzf go1.19.linux-amd64.tar.gz
- Install devel:
go install -v github.com/go-delve/delve/cmd/dlv@latest
What did you expect to see?
No error, devel is correctly installed
What did you see instead?
pkg/mod/github.com/hashicorp/golang-lru@v0.5.4/simplelru/lru.go:1:1: expected 'package', found 'EOF'

The problem has been resolved after I deleted go-build cache in
~/.cache/go-buildThis is currently the only report we have of this kind of corruption. It’s not clear to me whether this is a bug in Go, a bug in WSL2, or both. Moving to the Backlog pending more user reports and/or test failures that might shed some light for debugging.
@bcmills I’m on WSL. This is the result of
mount | column -tcommand:/dev/sdc on / type ext4 (rw,relatime,discard,errors=remount-ro,data=ordered)And for the second question, the answer is no (I already test it before opening the issue)Hello I face the same issue with 2 new packages (not link to delve) on an internal go projet:
../../go/pkg/mod/github.com/armon/go-radix@v1.0.0/radix.go:1:1: expected 'package', found 'EOF' ../../go/pkg/mod/github.com/mitchellh/mapstructure@v1.5.0/decode_hooks.go:1:1: expected 'package', found 'EOF'UsingGODEBUG=goindex=0fix the issue
