语法错误:createScript 中的令牌无效或意外 (vm.js:80:10) [英] SyntaxError: Invalid or unexpected token at createScript (vm.js:80:10)

问题描述

我刚刚开始学习 node，并在从 powershell 终端执行一个非常简单的应用程序时:

I've just arted to learn node, and when executing a very simple app from a powershell terminal:

node app.js

我收到以下异常:

SyntaxError: Invalid or unexpected token
    at createScript (vm.js:80:10)
    at Object.runInThisContext (vm.js:139:10)
    at Module._compile (module.js:607:28)

这是我的 app.js 源代码:

var express = require('express');

var app = express();

app.get('/', function(req, res){
    res.send('Hello from my libvrary app')
})

app.listen(3000, function(){
    console.log('listening on port 3000');
});

我做错了什么?

推荐答案

您尝试使用 Node编码问题>.有时，使用某些命令行实用程序创建的文件会对文件产生一些编码问题.所以，我建议不要使用它们来创建文件.只需使用 Right-Click > 创建文件新建文件app.js 并用这个 app.js 替换你的旧文件.并尝试运行 node app.js.

It looks like there is some encoding issue with the file that you're trying to run with Node. Sometimes, files created with some command line utility does some encoding issues with the file. So, I would suggest not to use them to create file. Just create file with Right-Click > New File > app.js and replace your old file with this app.js. And try running node app.js.
