taro编译错误UnhandledPromiseRejectionWarning: RangeError: Maximum call stack size exceeded

taro自己写的程序编译正常，但是从网上下载的taro项目却发现一个都编译不过。

编译命令npm  run dev:weapp 

错误如下：             
> [email protected] dev:weapp /opt/Miai
> npm run build:weapp -- --watch

> [email protected] build:weapp /opt/Miai
> taro build --type weapp "--watch"

? Taro v1.3.21

开始编译项目 Miai
