(from $GOROOT) ($GOPATH not set) in IntelliJ idea

Question

I've started using the golang in IntelliJ Idea.

I have the following code

package main

import (
    "fmt"
    "/github.com/zzz/stringutil"
)

func main() {
    fmt.Printf(stringutil.Reverse("!oG ,olleH"))
}

and also I have the following stringutil.go file

// Package stringutil contains utility functions for working with strings.
package stringutil

// Reverse returns its argument string reversed rune-wise left to right.
func Reverse(s string) string {
    r := []rune(s)
    for i, j := 0, len(r)-1; i < len(r)/2; i, j = i+1, j-1 {
        r[i], r[j] = r[j], r[i]
    }
    return string(r)
}

I'm receiving the following error:

src\github.com\zzz\hello\hello.go:5:2: cannot find package "src/github.com/zzz/stringutil" in any of:
    C:\Go\src\src\github.com\zzz\stringutil (from $GOROOT)
    ($GOPATH not set)

How can I configure the env variables through Intellij so I can run the program?

Answer 1

This is the quick fix for this issue. I am using inttelliJ idea as my editor. I am using MAC

1. Go to preferences
2. Search for GO under language & frameworks

3. If your look for GOROOT it should be like screen shot below

   

4. If you look for GOPATH the setting should be like screen shoot below

5. And this is my full path of the project. You can customize it to follow your needs. My project name is adit /Users/mmdc/Documents/mataharimall-development/www/go/src/github.com/mataharimall/adit

Answer 2

Yes, remove the slash of "/github.com/zzz/stringutil", like this "github.com/zzz/stringutil", you can use idea or vscode, it can auto add to imports, new golanger. ^_^'
