Binary using pkger not working outside of source folder

[ContiGuy]

Hi, I ran pkger in a go modules enabled project, built the binary and ran it from the source folder and it worked. When I run this binary from /tmp it fails.

log:

~/p/play-pkger (master|✚2…) $ cat cmd/play-pkger/play-pkger.go 
package main

import (
    "fmt"

    "github.com/markbates/pkger"
)

func main() {
    err := run()
    if err != nil {
        panic(err)
    }
}

func run() error {
    f, err := pkger.Open("/LICENSE")
    if err != nil {
        return err
    }
    defer f.Close()

    info, err := f.Stat()
    if err != nil {
        return err
    }

    fmt.Println("Name: ", info.Name())
    fmt.Println("Size: ", info.Size())
    fmt.Println("Mode: ", info.Mode())
    fmt.Println("ModTime: ", info.ModTime())
    return nil
}

It seems that this binary also would not work on a machine which doesn't have go installed.

I think pkged.go is not built in your binary.

Adding _ "path/to/your/module" in your imports should fix the problem.

[ContiGuy]

@nlepage Thanks for the reply! But unfortunately the import doesn't help.

Use pkger -o cmd/play-pkger to put the pkged.go file in the package you need it.

@ContiGuy what if you compile it on the current directory and then move the binary to /tmp ?

Also, what is your version of go ?
