# 如果你用一个独立包的模块: 
# 或者并不是安装全局模块
# 比如并不是在命令行通过输入npm install -g typings这种方式安装的. 
typings install angular --save
或者
cnpm install @types/angular  -g  //全局安装
cnpm install @types/node  -g
cnpm install @types/jquery  -g
cnpm install weinre -g    //安装调试工具
# 如果是通过script标记
# 或者是子环境的一部分
# 或者全局typings命令不可用的时候： 
typings install dt~mocha --global --save
其中"dt~"为使用DefinitelyTyped类型定义的意思，vscode可以识别这种定义。 
# 从其他版本处安装typings定义(比如env或者npm). 
typings install env~atom --global --save
typings install npm~bluebird --save
# 使用该文件`typings/index.d.ts` (在`tsconfig.json`文件使用或者用 `///` 定义). 
cat typings/index.d.ts
