电脑可以实现，手机提示出错 runtime.js?devtools_ignore=true:1 Error: module "pages/template/template.js" is not defined at require (eval at n.call.document (runtime.js?devtools_ignore=true:1), <anonymous>:2:1970413) at eval (eval at n.call.document (runtime.js?devtools_ignore=true:1), <anonymous>:2:1970034) at eval (index.js:4) at require (eval at n.call.document (runtime.js?devtools_ignore=true:1), <anonymous>:2:1970551) at eval (index.js:6) at eval (<anonymous>) at p (runtime.js?devtools_ignore=true:1) at runtime.js?devtools_ignore=true:1 at k (runtime.js?devtools_ignore=true:1) at w (runtime.js?devtools_ignore=true:1) ？？？？？？？
自定义，1、不好看；2、麻烦；3、易出错
建议微信官方修改支持在json中直接增加就行了，可以限制5个
看下文档,自定义tabbar，满足需求
建议自定义底部栏，官方文档里直接提供demo，但是个人觉得体验一般，组件渲染以及实际切换操作时会有卡顿，没有系统默认的流程。
自定义,根据不同权限,显示不同的tabBar
可以尝试使用自定义TableBar组件。
