問題描述開發項目中使用了vue+element-ui,在按需加載elementui模塊時這樣寫就會報錯，我加載了以下三個模塊。import {Message, Select, Cascader} from 'element-ui';控制臺報錯：[Vue warn]: Unknown custom element: <el-option> - did you register the component correctly? For recursive components, make sure to provide the "name" option.上面提示的錯誤是與Select模塊有關，所以最開始我以為是Select模塊的問題，所以我就把Select模塊禁用了。import { Message, Cascader } from 'element-ui';雖然沒有報錯，但是Message的警告樣式會在我頁面一刷新時就出現，正常情況下應該在觸發事件時才出現。然后我又禁用了Message模塊，報了同樣的錯誤?？刂婆_報錯：[Vue warn]: Unknown custom element: <el-option> - did you register the component correctly? For recursive components, make sure to provide the "name" option.之后我又多次嘗試各種寫法，最后我將Message模塊挑出來單獨引入，沒有報錯并且顯示正常。import Message from 'element-ui';import { Select, Cascader } from 'element-ui';但是會出現‘element-ui’多次入口的警告。這里要提一下，我在多個頁面都按需加載了elementUI的其他模塊，并沒有出現錯誤或警告。這里想請教大家有沒有遇到類似問題，該如何解決？
