解决执行Command报错executable file not found in $PATH

执行exec.Command时出现该问题。

执行模式为：

cmd := exec.Command(name, args...)

解决之道即将命令和参数分开传递

最后形式如:
cmd := exec.Command("/a/b", "-m", "abc", "-p", "123")

其中/a/b就是可执行程序。

而不是

cmd := exec.Command("/a/b -m abc -p 123")

由程序解析为可执行的一条命令并不是获得一个连续的字符串这么连贯的，还要考虑命令与参数的特殊处理。
