在$ PATH中找不到Unix可执行文件


I have a problem when using Go. Here is my code:

package main

import (

func main() {
    output, err := exec.Command("pwd").Output()
    fmt.Println(string(output), err)

    output, err = exec.Command("ls", "-l").Output()
    fmt.Println(string(output), err)

When I run this, I get the following errors.

err exec: "pwd": executable file not found in $PATH;

err exec: "ls": executable file not found in $PATH

I'm using Ubuntu 14.04.

    First I thought that the issue was caused because the code did not reside in ~/go/src/<bitbucket.org>/<username>/, but it turns out that it will also run successful if it is executed from the home directory, i.e. ~/. Probably, like already was mentioned in the comments, the commands pwd and ls were not in the path or the program was executed as another user.
