What did you do?

Tried to go list a module in $GOPATH/pkg/mod.

mkdir example && cd example
export GOPATH="$PWD"
mkdir main && cd main
cat > main.go <<EOF
package main

import "github.com/gocql/gocql"

func main() {
    gocql.NewCluster("192.168.1.1", "192.168.1.2", "192.168.1.3")
}
EOF
cat > go.mod <<EOF
module main

require github.com/gocql/gocql v0.0.0-20190208221138-c53c3654dc8a
EOF
go mod download
cd "$GOPATH/pkg/mod/github.com/gocql/gocql@v0.0.0-20190208221138-c53c3654dc8a" && go list

What did you expect to see?

$ go list
github.com/gocql/gocql

What did you see instead?

In go1.11.5:

$ cd "$GOPATH/pkg/mod/github.com/gocql/gocql@v0.0.0-20190208221138-c53c3654dc8a" && go list
go: writing go.sum: open $GOPATH/pkg/mod/github.com/gocql/gocql@v0.0.0-20190208221138-c53c3654dc8a/go.sum: permission denied

In go1.12rc1:

$ cd "$GOPATH/pkg/mod/github.com/gocql/gocql@v0.0.0-20190208221138-c53c3654dc8a" && go list
go: writing go.sum: open $GOPATH/pkg/mod/github.com/gocql/gocql@v0.0.0-20190208221138-c53c3654dc8a/go.sum389063318.tmp: permission denied

Sorry to comment.

#30185 redirect to #34054, but it seems this is by design?

gopls rely on go list, so if it's by design, how can we use gopl for project in $GOPATH/pkg/mod?

LSP :: Connected to [gopls:94397 status:starting].
LSP :: go [list -f {{context.GOARCH}} {{context.Compiler}} -- unsafe]: exit status 1: error writing go.mod: open $GOPATH/pkg/mod/github.com/cep21/circuit/v3@v3.1.0/go.mod298498081.tmp: permission denied

I file an issue to track.
