vue3项目如果启用typescript，单独引入ElMessage,ElMessageBox样式时写法略有不同，如下
代码语言：javascript复制import 'element-plus/es/components/message-box/style/index'
import 'element-plus/es/components/message/style/index'注，如果按以下写法会报错
代码语言：javascript复制import 'element-plus/es/components/message-box/style'
import 'element-plus/es/components/message/style'报错：
Module not found: Error: Can’t resolve ‘element-plus/es/components/message-box/style’ Module not found: Error: Can’t resolve ‘element-plus/es/components/message/style’
