NodeJs环境配置

*

1，下载路径
https://nodejs.org/en/download/

2，安装 express（之前用npm install -g express，一直提示出错，然后查资料说nodejs如果是4以上，
应该用express-generator）

D:ResourcesNODEJS odejs>npm uninstall -g express
npm WARN uninstall not installed in D:ResourcesNODEJS odejs ode_modules: "express"

D:ResourcesNODEJS odejs>npm install -g express-generator
D:ResourcesNODEJS odejsexpress -> D:ResourcesNODEJS odejs ode_modulesexpress-generatorinexpress
express-generator@4.13.4 D:ResourcesNODEJS odejs ode_modulesexpress-generator
├── sorted-object@2.0.0
├── mkdirp@0.5.1 (minimist@0.0.8)
└── commander@2.7.1 (graceful-readlink@1.0.1)

D:ResourcesNODEJS odejs>express -V
4.13.4

//创建helloworld的项目
D:ResourcesNODEJS odejs>express helloworld

create : helloworld
create : helloworld/package.json

*************helloworld.js//////
var http = require("http");
http.createServer(function(request, response) {
response.writeHead(200, {"Content-Type": "text/plain"});
response.write("Hello World");
response.end();
}).listen(8888);
console.log("nodejs start listen 8888 port!");

****************

D:ResourcesNODEJS odejs>cd helloworld

D:ResourcesNODEJS odejshelloworld>node helloworld.js
nodejs start listen 8888 port!

 打开地址http://127.0.0.1:8888/
发现输出 :
Hello World

*****************
1，cmd窗口，输入node，回车，输入"console.log("hello")",可以简单测试node.js
