webpack compiled with 4 errors

原因

沒有安裝相關(guān)的包

安裝一下

報(bào)錯(cuò)了

npm

使用管理身份運(yùn)行cmd，再換個(gè)命令

#這個(gè)版本是vue2.0的
npm install --save vue-router@3

再來解決 ‘element-ui’

先刪除node_modules
重新npm install
然后再安裝element-ui

npm install
npm install --save element-ui

最后重新運(yùn)行項(xiàng)目即可

npm run serve
