安卓打包后，安装运行闪崩，报错"withRef is removed...."

这个该怎么破，网上查了很多关于withRef is removed. To access the wrapped instance, use a ref on the connected component，都解决不了。追踪错误信息如下，

对了，忘了说，这个taro项目采用了dva，参照网上的说法应该是connect这里的问题：

import { connect } from "@tarojs/redux";
@connect(({ demo }) => ({
  ...demo
}))
class Demo extends Component<DemoProps, DemoState> {
}

com.facebook.react.common.JavascriptException:
这个错误是 React 报的。

参考一下这个：https://stackoverflow.com/questions/53819335/withref-is-removed-to-access-the-wrapped-instance-use-a-ref-on-the-connected-c/53819524

可能是 react-redux 版本太高导致的。

@蜘蛛paipai react-redux降级了到了5.x，编译的bundle中还是有withRef,安装运行还是同样的问题。

为了方便，我把重现代码放到了码云上，https://gitee.com/andyge/simple_taro_demo ,这个是测试端，里面用了dva，壳子的话就用 git clone git@github.com:NervJS/taro-native-shell.git获取吧。
