如何诊断"npm start"故障？

Question

我正在学习AngularJS。为此，我按照教程并检查了示例的代码（git clone --depth=14 https://github.com/angular/angular-phonecat.git）。

然后，我跑npm install npm install -g bower.

最后，我尝试使用 npm start 启动 Web 服务器。

它不起作用，我得到以下错误输出：

0 info it worked if it ends with ok
1 verbose cli [ 'C:\Program Files\nodejs\\node.exe',
1 verbose cli   'C:\Program Files\nodejs\node_modules\npm\bin\npm-cli.js',
1 verbose cli   'start' ]

我该如何解决它？

Answer 1

只需执行以下操作：

npm install

然后：

npm start

然后打开浏览器并浏览到：

http://localhost:8000

然后选择/app，您将被带到：

http://localhost:8000/app/#/phones

如果您仍然遇到问题，您可以执行以下操作，以使应用程序在没有测试的情况下运行。

npm install express --save

将以下代码作为服务器.js保存到根目录：

var express  = require('express');  
var http = require('http');
var app = express();        
app.set('port', process.env.PORT || 8000);
app.use(express.static(__dirname + '/app')); 
var server = http.createServer(app);
server.listen(app.get('port'), function() {
  console.log('Express HTTP server listening on port ' + app.get('port')  ) ;
});

然后做：

node server.js

现在浏览到：

http://localhost:8000
