angular-cli修改端口号

方法一：修改配置文件node_modules/angular-cli/lib/config/schema.json 

default值就是默认的端口:4200

"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"      }    }  }}

方法二：命令行修改端口号

ng server --port 4201

(ng serve --host localhost --port 4201)
