准备用vue做项目了，记录下我在做项目中遇到的问题

在运行vue项目中报错

npm ERR! sdms_project@0.1.0 serve: `vue-cli-service serve` npm ERR! Exit status 1 npm ERR! npm ERR! Failed at the sdms_project@0.1.0 serve script. npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

是端口被占用，在vue.config.js里改下端口就好。
