Nodejs - 将指挥官参数传递给永远监控子进程

Question

我有这个节点 cli 脚本

#!/usr/bin/env node
const path = require('path');
const forever = require('forever-monitor');
const script = path.format({dir: __dirname, base: 'pager.js'});
const chalk = require('chalk');
const commander = require('commander');

commander.version('1.0.0')
.option('-m, --message', 'set awesome message')
.parse();

const args = commander.opts();

const header = `
+---------------------+  
| Awesome v1.0 |
+---------------------+
`;

const child = new (forever.Monitor)(script, {
    max: 2,
    silent: false,
    args: args
});

child.start();

child.on('start', (process) => {
    console.log(chalk.magenta.bold(header));
});

child.on('restart', () => {
    console.log(`Forever restarting script for ${child.times} time`);
});

child.on('exit:code', (code) => {
    console.log(`Forever detected script exited with code ${code}`);
});

我想集成commander，让用户能够传递将被解析的参数，然后传递给正在运行的子进程，直到终端在forever-monitor npm 包的帮助下关闭。目前我尝试在子进程中使用指挥官但没有成功，它将被忽略。然后我将它移到我的index.js 代码中，但我不知道如何将参数传递给子进程。目前，如果我将解析的参数传递给永远监视器的args 选项，则会出现此错误

host:awesome dev$ node . -m 'Hello!'
/Users/dev/Desktop/awesome/node_modules/forever-monitor/lib/forever-monitor/monitor.js:130
    this.args.unshift(script);
              ^

TypeError: this.args.unshift is not a function

谁能给我一些帮助？

forever-monitor：传递给forever-monitor 的args 配置选项需要一个数组。

'args':    ['foo','bar']

Commander：program.opts() 返回一个常规的 javascript 对象，它是一个散列，键是选项名称。 program.args 是已解析的命令参数数组，其中已删除可识别的选项和选项值。

在 Commander 中，还可以查看 .allowUnknownOption() 和 passThroughOptions()，以便 Commander 在命令行上允许无法识别的选项。默认行为是为无法识别的选项显示错误。
