The package “github.com/tcratius/hello” has to exist in the GOPATH, in your case “/root/go”, or in your GitHub profile, installing:

go get github.com/tcratius/hello

[tcratius (Conrad Thiele)]

github.com/tcratius/hello is just a directory on my computer, not linked to github.

go get github.com/tcratius/hello

# cd .; git clone https://github.com/tcratius/hello /root/go/src/github.com/tcratius/hello
Cloning into '/root/go/src/github.com/tcratius/hello'...
fatal: could not read Username for 'https://github.com': terminal prompts disabled
package github.com/tcratius/hello: exit status 128

[luk4z7 (Lucas Alves)]

mkdir -p $( echo $GOPATH)/src/github.com/tcratius/hello
vim $( echo $GOPATH)/src/github.com/tcratius/hello/main.go

Put in your main.go

package main

import (
	"fmt"
)

func main() {
	fmt.Println("Hello")
}

Install again

go install github.com/tcratius/hello

And execute

hello

Cheers, I am not very good with vim so used nano. If I created a main.go then I have to point $GOPATH to it?

[luk4z7 (Lucas Alves)]

@tcratius

github.com/tcratius/hello

No, if you created main.go inside the “github.com/tcratius/hello”, only execute:

go install github.com/tcratius/hello

Remember that “github.com/tcratius/hello” should be within “$GOPATH/src/”

I think I’m getting the hang of it now. Thanks for your help
