贴一下相关的代码，以及报错那里可以点进去看下错在那一行

[mienv567]

错误地方：webpack:///./node_modules/@tarojs/router/dist/index.js?e6ae
错误行897： _this = _possibleConstructorReturn(this, _getPrototypeOf(WrappedComponent).call(this, props, context));
编译后的h5文件位置下的代码 .temp/app.js

看一下的根目录的 .babelrc

看一下的根目录的 .babelrc

没有这个文件

@yuche @luckyadam 看来还是tao-h5转换问题，现在所有小程序转成h5可以打开页面啦。所有页面操作按钮均可，只有css有点问题。我试着自己解决。使用的是最新版。
