系统找不到指定的路径/指定的文件grafana

I've been trying to build grafana from its source code on windows by following the instructions here

I am stuck and am failing to set the GOPATH path properly. I set it to the default go directory in C:\myname but whenever I try to change to that directory using the command "cd $GOPATH/src/github.com/grafana/grafana" it says the system cannot find the specified path. And even if I put the path manually and in the directory try to run "go run build.go setup" the system cannot find the file specified.

If someone could help me that'd be great!

Try to create a new empty folder:

mkdir C:\myFolder
cd C:\myFolder
set GOPATH=C:\myFolder
go get github.com/grafana/grafana

That should create a src\github.com\grafana\grafana folder, with the sources inside.
