Throw class not defined if decorator before export

[zqjimlove]

问题描述

当修饰符用在export之前，各个环境下都报not defined 错误。

复现步骤

具体看代码

@connect(
  ({apply}) => ({apply}),
  dispatch => ({
    updateOrderInfo: () => dispatch(updateOrderInfo())
  })
)
export default class chooseBank extends Component {

}

期望行为

成功运行

报错信息

ReferenceError: chooseBank is not defined

补充信息

使用 babel 直接编译的代码能看到

var chooseBank = (_dec = (0, _redux.connect)();
Page(__webpack_require__(/*! @tarojs/taro-swan */ "./node_modules/@tarojs/taro-swan/index.js").default.createComponent(chooseBank, true));

但经过taro的会变成

_class = (_dec = (0, _redux.connect)();
Page(__webpack_require__(/*! @tarojs/taro-swan */ "./node_modules/@tarojs/taro-swan/index.js").default.createComponent(chooseBank, true));

export 和 class 分开写

class MyClass {}
export default MyClass
