英文:
Unix executable files not found in $PATH
问题
我在使用Go语言时遇到了一个问题。以下是我的代码：
package main
import (
"fmt"
"os/exec"
)
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)
}
当我运行这段代码时，我得到了以下错误信息：
err exec: "pwd": 在 $PATH 中找不到可执行文件；
err exec: "ls": 在 $PATH 中找不到可执行文件
我正在使用的是 Ubuntu 14.04 操作系统。

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

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

首先，我认为问题是由于代码不位于~/go/src/<bitbucket.org>/<username>/目录中引起的，但事实证明，如果从主目录即~/执行，它也会成功运行。可能，就像评论中已经提到的那样，pwd和ls命令不在路径中，或者程序是以另一个用户身份执行的。
英文:
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.
