module.exportDefault不是一个函数

Question

我不确定这是否是Meteor的问题，但我在那里找不到任何类似的东西。

版本:Metoror2.0-Beta.4，但也包括Meteor 1.11、1.12

使用新签出和meteor npm安装，我运行应用程序，服务器正在运行，然后在Chrome控制台中收到一个javascript错误：

Uncaught TypeError: module.exportDefault is not a function

看一下源代码，我可以看出这是一个系统性的问题。就好像巴别塔把它编译错了一样

MemoryRouter.propTypes = {
  initialEntries: PropTypes.array,
  initialIndex: PropTypes.number,
  getUserConfirmation: PropTypes.func,
  keyLength: PropTypes.number,
  children: PropTypes.node
};
module.exportDefault(MemoryRouter);
/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

},"Router.js":function module(require,exports,module){

// node_modules/react-router/es/Router.js                                                                              //
//                                                                                                                     //

我尝试过更新babel库，但没有成功:(

任何想法都将不胜感激

更新@1/12/20

meteor add modules不能工作(可惜，它会很好)

我已经知道它与一个或多个npm模块相关。如果我保留一个正常工作的包-lock.json，它可以正常工作，但是如果我删除它并执行一个meteor npm install，那么我会得到这个错误。我看到一些巨大的内存使用量和糟糕的性能(甚至在Meteor 1.11.1中也是如此)，这可能与此有关。npm更新了太多的包，不能很容易地找到罪魁祸首。

Answer 1

我个人从未使用过Meteor，但从它的外观来看，Meteor需要定义exportDefault。看一看这个issue，似乎meteor install modules需要恰好支持exportDefault。
