angular-cli修改端口号【angular2】

找到node_modules/angular-cli/lib/config/schema.json

default值就是默认的端口

"serve": {
 "description": "Properties to be passed to the serve command",
 "type": "object",
 "properties": {
  "port": {
  "description": "The port the application will be served on",
  "type": "number",
  "default": 4200
  },
  "host": {
  "description": "The host the application will be served on",
  "type": "string",
  "default": "localhost"
  }
 }
 }
}

也可以通过命令行方式修改，如：

ng serve --port 4201
