common problems during initial setup of AngularJS 2

My background is in PHP and JavaScript, and I have limited experience with nodejs and angular js. While attempting to learn angular js 2, I encountered difficulties setting up my first example.

I am using node v 5.6.0 and npm version 3.7.2 on ubuntu 14.04.

I followed this article, but had to make a change due to the deprecation of tsd. I used typings instead of tsd. Below is the structure of my folders. https://i.sstatic.net/e28kG.png

However, when I run gulp buildServer in the terminal, it gives me the following errors.

I believe I may be making a simple mistake. If you could help me solve this issue or need more information, please let me know.

server.ts contains the following code:

import express = require('express');
import path = require('path');
var port: number = process.env.PORT || 3000;
var app = express();

app.use('/app', express.static(path.resolve(__dirname, 'app')));
app.use('/libs', express.static(path.resolve(__dirname, 'libs')));

var renderIndex = (req: express.Request, res: express.Response) => {
    res.sendFile(path.resolve(__dirname, 'index.html'));
}

app.get('/*', renderIndex);

var server = app.listen(port, function() {
    var host = server.address().address;
    var port = server.address().port;
    console.log('This express app is listening on port:' + port);
});

Answer №1

Make sure to install the type definitions for both node and serve-static.

typings install node --ambient --save
typings install serve-static --ambient --save
typings install mime --ambient --save

Don't forget to also install mime as it is required by serve-static.

Answer №2

When encountering the error message 'path' module not found, followed by similar issues with http and other modules, it could be related to using an outdated version of npm. This is because starting from npm v3.0, it aims to flatten all dependencies as explained in this article.

To troubleshoot, you can try deleting the node_modules directory, installing the latest stable versions of node and npm, running npm install again, and then attempting to run your gulp tasks. It's also a good idea to verify your current npm and node versions.
