I'm Ubuntu 21.04 user and I'm trying to use "github.com/golang/protobuf/protoc-gen-go/grpc" lib and I'm confused if my $GOPATH should be GOPATH=$HOME/go or GOPATH=usr/local/go. Because I installed my grpc into GOPATH=$HOME/go, but VSCODE could not find it, just libs in usr/local/go.
May seem obvious to be usr/local/go, but I see everywhere people using $GOPATH as GOPATH=$HOME/go.
The PATH to the go tool should be set. However, GOROOT doesn't need to be set and will be deterined by the go tool when it runs. GOPATH defaults to $HOME/go and doesn't need to be set unless you want to move it elsewhere. With Go Modules, GOPATH is only used to store downloaded/cached modules, compiled objects, and go install binaries. Your source can live in any directory underneath a go.mod file.
