1、用npm init命o(h)初始化包配置理文gpackage.json
2、添加插件npm插g
npm install grunt --save-dev
npm install grunt-cli --save-dev
npm install grunt-babel --save-dev
npm install grunt-contrib-concat --save-dev
npm install grunt-contrib-jshint --save-dev
npm install grunt-contrib-uglify --save-dev

最后package.json配置文g如下所C?br />

在公交R上刷微博Q还是有很多同学在咨?

  • 如何快速搭?node 开发环?/li>
  • npm 慢
  • github 无法打开的问?/li>

于是我觉得应该写一文章解{所有这些v步问题，让新同学也能顺利利入门?/p>

快速搭?Node.js 开发环?/h2>

如果你想长期?node 开? 或者想快速更?node 版本, 或者想快速切?node 版本, 那么?strong>?Windows(?osx, linux) 环境? 请?nvm 来安装你?node 开发环? 保持pȝ的干净.

如果你?Windows 做开? 那么你可以?nvmw 来替?nvm

osx, linux 环境

如果你是 windows 环境开? 误q这? 直接查看下一?

git clone nvm

直接?github clone nvm 到本? q里假设大家都?~/git 目录存放 git 目:

$ cd ~/git $ git clone https://github.com/cnpm/nvm.git

配置l端启动时自动执?source ~/git/nvm/nvm.sh, ?~/.bashrc, ~/.bash_profile, ~/.profile, 或?~/.zshrc 文gd以下命o(h):

source ~/git/nvm/nvm.sh

重新打开你的l端, 输入 nvm

$ nvm  Node Version Manager  Usage:     nvm help                    Show this message     nvm --version               Print out the latest released version of nvm     nvm install [-s] <version>  Download and install a <version>, [-s] from source     nvm uninstall <version>     Uninstall a version     nvm use <version>           Modify PATH to use <version>     nvm run <version> [<args>]  Run <version> with <args> as arguments     nvm current                 Display currently activated version     nvm ls                      List installed versions     nvm ls <version>            List versions matching a given description     nvm ls-remote               List remote versions available for install     nvm deactivate              Undo effects of NVM on current shell     nvm alias [<pattern>]       Show all aliases beginning with <pattern>     nvm alias <name> <version>  Set an alias named <name> pointing to <version>     nvm unalias <name>          Deletes the alias named <name>     nvm copy-packages <version> Install global NPM packages contained in <version> to current version  Example:     nvm install v0.10.24        Install a specific version number     nvm use 0.10                Use the latest available 0.10.x release     nvm run 0.10.24 myApp.js    Run myApp.js using node v0.10.24     nvm alias default 0.10.24   Set default node version on a shell  Note:     to remove, delete or uninstall nvm - just remove ~/.nvm, ~/.npm and ~/.bower folders

通过 nvm 安装L版本?node

$ nvm install 0.12.0

于是你就?x)看CD非常快速进度条:

######################################################################## 100.0% Now using node v0.12.0

q可以直接安?iojs 各个版本

$ nvm install iojs

你可以l非常方便地安装各个版本?node ? 你可以查看一下你当前已经安装的版?

$ nvm ls-remote          nvm      v0.8.26     v0.10.26     v0.11.16 ->  v0.12.0

windows 环境

git clone nvmw

直接?github clone nvmw 到本? q里假设大家都?d:\git 目录存放 git 目:

$ d: $ cd git $ git clone https://github.com/cnpm/nvmw.git

讄 d:\git\nvmw 目录C?PATH 环境变量?

set "PATH=d:\git\nvmw;%PATH%"

重新打开你的l端, 输入 nvmw

$ nvmw  Usage:   nvmw help                    Show this message   nvmw install [version]       Download and install a [version]   nvmw uninstall [version]     Uninstall a [version]   nvmw use [version]           Modify PATH to use [version]   nvmw ls                      List installed versions  Example:   nvmw install v0.6.0          Install a specific version number   nvmw use v0.6.0              Use the specific version

通过 nvmw 安装L版本?node

$ nvmw install 0.12.0

于是你就?x)看CD非常快速进度条:

######################################################################## 100.0% Now using node v0.12.0

安装 iojs

$ nvmw install iojs-1.4.2

然后你可以l非常方便地安装各个版本?node ? 你可以查看一下你当前已经安装的版?

$ nvmw ls  v0.10.26 v0.11.12 Current: v0.11.12

到此, 无论?windows 环境, q是 osx, linux 环境, 都能快速安装多个版本的 node ?

使用 cnpm 加?npm

同理 nvm , npm 默认是从国外的源获取和下载包信息, 不慢才奇? 可以通过单的 ---registry 参数, 使用国内的镜?http://registry.npm.taobao.org :

$ npm install koa --registry=http://registry.npm.taobao.org

于是屏幕又哗啦哗啦地一大片输出:

$ npm install koa --registry=http://registry.npm.taobao.org ... koa@0.5.2 node_modules/koa ├── koa-compose@2.2.0 ├── statuses@1.0.2 ├── finished@1.1.1 ├── escape-html@1.0.1 ├── only@0.0.2 ├── debug@0.8.0 ├── fresh@0.2.2 ├── type-is@1.0.1 ├── delegates@0.0.3 ├── mime@1.2.11 ├── co@3.0.5 ├── accepts@1.0.1 (negotiator@0.4.2) └── cookies@0.4.0 (keygrip@1.0.0)

但是毕竟镜像跟官方的 npm 源还是会(x)有一个同步时间差? 目前 cnpm 的默认同步时间间隔是 10 分钟. 如果你是模块发布? 或者你想马上同步一个模? 那么推荐你安?cnpm cli:

$ npm install cnpm -g --registry=http://registry.npm.taobao.org

通过 cnpm 命o(h)? 你可以快速同步Q意模?

$ cnpm sync koa connect mocha

? 我就是不惛_?cnpm cli 怎么? 哈哈, 早就惛_你会(x)q么懒了, 于是我们q有一?web 面:

例如我想马上同步 koa, 直接打开览? http://npm.taobao.org/sync/koa

或者你是命令行? 通过 open 命o(h)打开:

$ open http://npm.taobao.org/sync/koa

如果你安装的模块依赖?C++ 模块, 需要编? 肯定?x)通过 node-gyp 来编? node-gyp 在第一ơ编译的时? 需要依?node 源代? 于是又会(x)?node dist 下蝲, 于是大家又会(x)吐槽, 怎么 npm 安装q么?..

好吧, 于是又要提到 --disturl 参数, 通过中国镜像来下?

$ npm install microtime \   --registry=http://registry.npm.taobao.org \   --disturl=http://npm.taobao.org/mirrors/node

再次要提?cnpm cli, 它已l默认将 --registry ?--disturl 都配|好? 谁用谁知?. 写到q里, 更快疑惑那些不惛_?cnpm cli 又吐?npm 慢的同学是基于什么考虑不在本地安装一?cnpm ?

github 好慢

好了, 看到q里大家应该?node ?npm 已经没有速度慢的问题?

github ? 或者说是它的资?host 被堵而已, 大家可以通过单的 hosts 映射解决:

185.31.16.184 github.global.ssl.fastly.net

Z最q访问国外网站这么慢?

听说?APCN2 又断? http://weibo.com/1415338244/ACTYkq8xK

希望文本对你有用. :)
