I have no experience programming go, however i did some PHP for serveral years. I did some research and Go looks very interesting to learn.
As a webdeveloper there was no ‘hard’ setup for any environment, just write some code and upload the file, so installing Go is kind of new for me.
I installed succesfuly GoLang and the Go Server is running on my machine.
I created a new directory for the src, pkg and bin.
I changed the GOBIN en GOPATH
I created a hello.go file
But i cannot run or build the code.

C:\Users\Bas>go run d:\gocode\src\hello
package d:/gocode/src/hello: cannot find package “d:/gocode/src/hello” in any of:
C:\Go\src\d:\gocode\src\hello (from $GOROOT)
D:\gocode\src\d:\gocode\src\hello (from $GOPATH)
I wouldn’t put any source in $GOPATH. I would put it anywhere in my profile/homedirectory and if it is a simple one/two file program with no external dependencies would i run it and and build it with for example go run hello.go or build it with go build -o hello hello.go
On the otherhand if it is a program with external dependencies would I make a folder and init a module inside it:
You could really name your module anything but If you uses github it will be best to name it after the repo. Modules are new in go 10.11 and is the future. Sadly if you google on the internet will you find a lot of examples of people putting stuff into the GOPATH. Read more about modules here: https://github.com/golang/go/wiki/Modules
A bit embarrising but i think i installed the packages and compiler (?) on my C drive, while the gocode dir is located on D. Could this be the problem ?
I preffer the current location: D > gocode > src, pkg and bin, because it is very clean and easy to navigate.
Should I re-install GoLang too the D drive ? I do not use Gitbub btw.
package main
import "fmt"
func main() {
fmt.Printf("hello, world\n")
