当我运行

时,任何人都知道我为什么会收到以下错误
const cp = require('child_process');
const _tty = cp.execSync('tty');

...我们收到此错误:

Error: Command failed: tty

不知道为什么会发生错误,因为我可以运行&#34; tty&#34;从任何终端(没有root权限?)

答案 0 :(得分:2)

在Node.js专家的帮助下,我想出了这个。

这会给你一个未指定的错误(OP中的错误)

const _tty = cp.execSync('tty');

然而,这将为您提供所需的信息:

const _tty = cp.execSync('tty', {stdio:['inherit','pipe','pipe']});
