nodejs在windows下面环境搭建

近期nodejs很火，打算安装起来体验一下，首先安装nodejs的基础运行环境，然后安装web开发框架express

一：下载node.js,官网地址https://nodejs.org/en/ 我下载的是7.3.0最新版本

download以后，开始安装，windows的安装最简单了，不说了，下一步即可。

二：安装好nodejs以后，代开CMD，执行node -v 查看是否安装成功，正常后有版本打印出来，在测试下npm是否安装成功，在安装nodejs的时候一起安装的，npm -v 查看

三： install express

进入CMD，执行npm install -g express-generator

npm install -g express

等待安装完成

-h, --help output usage information
--version output the version number
-e, --ejs add ejs engine support
--pug add pug engine support
--hbs add handlebars engine support
-H, --hogan add hogan.js engine support
-v, --view <engine> add view <engine> support (ejs|hbs|hjs|jade|pug|twig|vash) (defaults to jade)
-c, --css <engine> add stylesheet <engine> support (less|stylus|compass|sass) (defaults to plain css)
--git add .gitignore
-f, --force force on non-empty directory

error: unknown option `-V'

D:\work-space\nodejs>express -v

Usage: express [options] [dir]

Options:

-h, --help output usage information
--version output the version number
-e, --ejs add ejs engine support
--pug add pug engine support
--hbs add handlebars engine support
-H, --hogan add hogan.js engine support

四：建立一个项目

写道

D:\work-space\nodejs>express testexpress

warning: the default view engine will not be jade in future releases
warning: use `--view=jade' or `--help' for additional options

create : testexpress
create : testexpress/package.json
create : testexpress/app.js
create : testexpress/public
create : testexpress/routes
create : testexpress/routes/index.js
create : testexpress/routes/users.js
create : testexpress/views
create : testexpress/views/index.jade
create : testexpress/views/layout.jade
create : testexpress/views/error.jade
create : testexpress/bin
create : testexpress/bin/www
create : testexpress/public/javascripts
create : testexpress/public/images
create : testexpress/public/stylesheets
create : testexpress/public/stylesheets/style.css

install dependencies:
> cd testexpress && npm install

run the app:
> SET DEBUG=testexpress:* & npm start

express的默认模版采用jade，若需要ejs模版支持，加上-e选项，即 express -e testexpress

D:\work-space\nodejs\testexpress>

node_modules, 存放所有的项目依赖库。(每个项目管理自己的依赖，与Maven,Gradle等不同)
package.json，项目依赖配置及开发者信息
app.js，程序启动文件
public，静态文件(css,js,img)
routes，路由文件(MVC中的C,controller)
Views，页面文件()

五：运行项目

写道

写道

D:\work-space\nodejs\testexpress>npm start

> [email protected] start D:\work-space\nodejs\testexpress
> node ./bin/www

Welcome to Express

这样，环境就安装好了。。

具体的代码开发，使用文本编辑器就可以比如sublime
