最近打开这个项目，yarn dev:weapp 时候报错，cli 和项目版本冲突如下：

kyle@DESKTOP-LIPAM5T MINGW64 /d/yuwei-workspacke/web-frontend/icommunity/weapp-fontend/trunk/icommunity-weapp (master)
$ yarn dev:weapp
yarn run v1.22.4
$ npm run build:weapp -- --watch

> icommunity-miniapp@1.0.0 build:weapp D:\yuwei-workspacke\web-frontend\icommunity\weapp-fontend\trunk\icommunity-weapp
> taro build --type weapp "--watch"

� Taro v2.1.5

开始编译项目 icommunity-miniapp
错误  版本问题  Taro CLI 与本地安装运行时框架 @tarojs/taro-weapp 版本不一致, 请确保版本一致！
提示  升级命令  升级到最新CLI：taro update self   升级到最新依赖库：taro update project
提示  升级文档  请参考 "常用 CLI 命令"中"更新" 章节：https://taro-docs.jd.com/taro/docs/GETTING-STARTED.html
