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": 4205
},
"host": {
"description": "The host the application will be served on.",
"type": "string",
"default": "localhost"
},
angular2有所不同,angular2的路径在node_modules/angular-cli/lib/config/schema.json
也可以通过命令行方式修改,如:
ng serve --port 4201
*如果修改不成功,可以尝试将端口换为4205或其他端口
