无法使用节点运行服务器

我是节点js和编程的新手。我在运行服务器时遇到问题。这就是我所做的

1)安装Express

sudo npm install -g express-generator

2)安装依赖项

cd  . && sudo npm install

当我在终端跑步时:

node app.js OR node app

对于服务器是否正在运行没有响应,并且当我路由到localhost:3000时,chrome表示没有收到任何数据。我后来发现正确的方法是运行

npm start 

相反,但我得到了这个:

npm ERR! express@0.0.1 start: `node ./bin/www`
npm ERR! Exit status 1
npm ERR! 
npm ERR! Failed at the express@0.0.1 start script.
npm ERR! This is most likely a problem with the express package,
npm ERR! not with npm itself.
npm ERR! Tell the author that this fails on your system:
npm ERR!     node ./bin/www
npm ERR! You can get their info via:
npm ERR!     npm owner ls express
npm ERR! There is likely additional logging output above.

怎么了?

当您运行node app.js时,您获得了什么回报?

另外,请确保您的app.js位于您所在的文件夹内。

Express生成器不会为您生成快递,它只会安装express工具来生成项目。

sudo npm install -g express-generator

安装express-generator后;问题express为您生成项目;

$ express myapp

// generate myapp with initial express files

$ cd myapp && npm install

// now you run the app
$ ./bin/www

// or
$ npm start
