现在，可以按如下方式使用shelljs（从节点v4）：

var shell = require('shelljs');

shell.echo('hello world');
shell.exec('node --version');

使用安装

npm install shelljs

我刚刚编写了一个Cli-helper来轻松处理Unix/windows。

Java脚本：

define(["require", "exports"], function (require, exports) {
    /**
     * Helper to use the Command Line Interface (CLI) easily with both Windows and Unix environments.
     * Requires underscore or lodash as global through "_".
     */
    var Cli = (function () {
        function Cli() {}
            /**
             * Execute a CLI command.
             * Manage Windows and Unix environment and try to execute the command on both env if fails.
             * Order: Windows -> Unix.
             *
             * @param command                   Command to execute. ('grunt')

Example of use:

        console.log('Grunt has been automatically executed. (' + env + ')');

    }, function (command, args, env) {
        console.error('------------- Windows "' + command + '" command failed, trying Unix... ---------------');

    }, function (command, args, env) {
        console.error('------------- Unix "' + command + '" command failed too. ---------------');
    });

由于版本4，最接近的替代方法是child_process.execSync方法：

const {execSync} = require('child_process');

let output = execSync('prince -v builds/pdf/book.html -o builds/pdf/book.pdf');

⚠️ 请注意，execSync调用会阻塞事件循环。

@六氰的答案几乎是完整的。在Windows命令prince可以是prince.exe、prince.cmd、prince.bat或prince（我不知道gems是如何绑定的，但npm bin附带了sh脚本和批处理脚本-npm和npm.cmd）。如果你想编写一个在Unix和Windows上运行的可移植脚本，你必须生成正确的可执行文件。

这里有一个简单但可移植的派生函数：

function spawn(cmd, args, opt) {
    var isWindows = /win/.test(process.platform);

    if ( isWindows ) {
        if ( !args ) args = [];
        args.unshift(cmd);
        args.unshift('/c');
        cmd = process.env.comspec;
    }

    return child_process.spawn(cmd, args, opt);
}

var cmd = spawn("prince", ["-v", "builds/pdf/book.html", "-o", "builds/pdf/book.pdf"])

// Use these props to get execution results:
// cmd.stdin;
// cmd.stdout;
// cmd.stderr;

如果您不介意依赖关系，并且希望使用promise，那么子进程promise可以：

安装

npm install child-process-promise --save

exec用法

var exec = require('child-process-promise').exec;
 
exec('echo hello')
    .then(function (result) {
        var stdout = result.stdout;
        var stderr = result.stderr;
        console.log('stdout: ', stdout);
        console.log('stderr: ', stderr);
    })
    .catch(function (err) {
        console.error('ERROR: ', err);
    });

派生用法

var spawn = require('child-process-promise').spawn;
 
var promise = spawn('echo', ['hello']);
 
var childProcess = promise.childProcess;
 
console.log('[spawn] childProcess.pid: ', childProcess.pid);
childProcess.stdout.on('data', function (data) {
    console.log('[spawn] stdout: ', data.toString());
});
childProcess.stderr.on('data', function (data) {
    console.log('[spawn] stderr: ', data.toString());
});
 
promise.then(function () {
        console.log('[spawn] done!');
    })
    .catch(function (err) {
        console.error('[spawn] ERROR: ', err);
    });

ECMAScript模块导入。。。from语法

import {exec} from 'child-process-promise';
let result = await exec('echo hi');
console.log(result.stdout);

您正在查找child_process.exec

以下是示例：

const exec = require('child_process').exec;
const child = exec('cat *.js bad_file | wc -l',
    (error, stdout, stderr) => {
        console.log(`stdout: ${stdout}`);
        console.log(`stderr: ${stderr}`);
        if (error !== null) {
            console.log(`exec error: ${error}`);
        }
});
