Rn-babelHelpers.objectDestructuringEmpty

[jaikensai888]

在React-native 中使用了dva 出现了babelHelpers.objectDestructuringEmpty 错误，这个错误在打开了hotLoading模式后消失。求解决方案.谢谢 @sorrycc 。我的配置是参考 react-native-dva-starter的
.babelrc:
{
"presets": [
"react-native"
],
"plugins": [
"transform-decorators-legacy",
[
"import",
{
"libraryName": "antd-mobile"
}
]
]
}

npm:
"dependencies": {
"antd-mobile": "^1.1.3",
"axios": "^0.16.1",

没明白问题，但感觉和 dva 无关。

跟 dva 无关，应该是代码写错了，看看这个 facebook/react-native#4831 (comment)

问题原因找到了，错误是因为在effect中使用了{}作为值

 effects: {
        *method({ payload: {  }}, { select,call, put }) {
        },

在关闭了hotModel 之后 payLoad这种参数为{}的写法不被支持；
修改成下面的方法，就没有报错了：

 effects: {
        *method({ payload}, { select,call, put }) {
        },

@nihgwu @sorrycc thank you all the same
