hello.go：1：1：非法字符U + 0023

Question

I'm trying to run the hello world from golang in this link But when I run go install, I'm getting this error:

hello.go:1:1: illegal character U+0023

This is my hello.go

package main    
import "fmt"
func main() {
  fmt.Printf("hello, world")
}

I'm using Mac OS El Captain What is wrong?

Answer 1

you have '#' in first line of your code which is invalid,
see this test sample code:

# just remove this line
package main

import "fmt" 

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

this will give this error:

hello.go:1:1: illegal character U+0023 '#'

but if you remove lines containing # it works fine:

package main

import "fmt"

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

it seems your IDE is not for Go. See:
