需求中有个页面是带导航的List列表，想来这么常见的需求定会有轮子可用，找了一通发现滴滴的开源库cube-ui实现了此功能，但在集成使用的过程中也遇到了一些问题，在此记录。

错误信息：

These relative modules were not found:

• ./cubeic.ttf in ./node_modules/css-loader??ref–11-oneOf-3-1!./node_modules/postcss-loader/src??ref–11-oneOf-3-2!./node_modules/stylus-loader??ref–11-oneOf-3-3!./node_modules/cube-ui/src/common/stylus/index.styl
• ./cubeic.woff in ./node_modules/css-loader??ref–11-oneOf-3-1!./node_modules/postcss-loader/src??ref–11-oneOf-3-2!./node_modules/stylus-loader??ref–11-oneOf-3-3!./node_modules/cube-ui/src/common/stylus/index.styl

出现这个错误是因为在安装cube-ui时，没有根据vue版本而采用不同的方式。官方文档说的很明白，如果vue-cli的版本 >= 3, 直接执行vue add cube-ui即可；如果 < 3，则执行npm install cube-ui --save安装，还要修改一系列的配置。注意：vue-cli的版本不同，创建项目的方式也不同，vue2创建项目vue init webpack ***，vue3创建项目vue create ***，如果用的是vue3的版本，但创建项目时执行的指令用的vue2的，也就相当于创建了一个vue2版本的项目，也会出现上述错误。

步骤：

创建项目：vue create vue3pro；

安装脚手架：vue add cube-ui ， 根据提示选择安装配置项；

按需引入：在main.js中添加

import {
    Style,
    IndexList,
} from 'cube-ui'
Vue.use(IndexList);
