想要引入外部的库：
import Collections = require('typescript-collections');
配置如下：
{
"compilerOptions": {
"module": "commonjs",
"target": "es5",
"sourceMap": true,
"moduleResolution": "node",
"lib": [
"dom",
"es5"
]
},
"exclude": [
// "node_modules"
]
}
报错
ReferenceError: exports is not defined
生成的js是[code]Object.defineProperty(exports, "__esModule", { value: true });
var Collections = require("typescript-collections");[/code]
刚接触ts，不太清楚怎么加载模块，编译时module是不是只能选commonjs？
