节点`require（'child_process'）。exec`非常严重地失败

Question

问题

模块exec的

child_process函数在执行openvpn --version时引发错误。当我将命令更改为zsh --version或echo $(openvpn --version)之类的命令时，不会发生此错误。

此外，直接在shell上执行openvpn --version时没有错误出现。

代码

const util = require('util');
const exec = util.promisify(require('child_process').exec);

(async () => {
    const cmd = 'openvpn --version'
    try {
        const {stdout, stderr} = await exec(cmd);
        console.log(stdout);
    } catch (err) {
        console.error(err);
    }
})();   

输出

{ Error: Command failed: openvpn --version
