ionic3 懒加载
ionic3 懒加载
第一步：增加module.ts
第二部：去掉app.module.ts中重复的部分
第三步：在对应页面的.ts文件里增加@IonicPage()特性(以home.ts为例)
第四步：使用懒加载（只需要将之前的页面名字用引号引起来即可，对应的也不需要在顶部进行import导入）
app.component.ts
tabs.ts
第五步：懒加载运行效果图
首次进入的时候，只加载了tabs和tool,切换的时候才会加载home
如果报错，查看下当前配置环境

删掉node_modules，然后npm install
如果还报错，就把app-scripts升级到最新版本试一试
