创建一个空项目，在项目根目录创建一个tsconfig.json文件
自动配置：

打开终端输入tsc --init，即可自动生成tsconfig.json文件
手动配置：

在项目根目录下新建一个tsconfig.json文件,并配置如下内容

具体配置可以直接使用下面的配置，详细配置可以去官网查考每一个属性对应的作用

 配置TS

配置TS文件监控

创建一个TS

class Student {
  fullName: string;
  constructor(public firstName: any, public middleInitial: any, public lastName: any) {
    this.fullName = firstName + " " + middleInitial + " " + lastName;
  }
}
interface Person {
  firstName: string;
  lastName: string;
}
function greeter(person: Person) {
  return "Hello, " + person.firstName + " " + person.lastName;
}
let user = new Student("Jane", "M.", "User");
console.log(greeter(user));

编译生成JS

tsc src/classGreeter

运行： node .\src\classGreeter.js

直接右键run命令

run这个命令，这个时候进行如下操作：

①安装直接运行所需依赖包： npm install -g ts-node

2.安装插件：Run Configuration for TypeScript

 在插件里安装失败

直接去网页： Run Configuration for TypeScript - IntelliJ IDEs Plugin | Marketplace下载jar包，然后导入插件也可以用

右键运行效果
