为什么在GO init()方法中出现错误?

So I understand that in go, init() is a special method that can be used to initialize an object in a package. When I try to use this technique, I get an error that the variable is declared and not used. For example:

package fizzbuzz

var foo string

func init() {
    foo := "bar"
}

It seems to me that most of the time variables that you put in this method will not be used local to int(), so that is just fine. What am I missing?

    That just creates a local variable named "foo" inside the method. You need to assign the string to the already declared var at the module scope via foo = "bar".
