Question

我已经使用了几个月没有问题的代码，但是在运行npm install并重新安装我的node_modules后，它已经停止工作。

import { Footer } from 'components/common';

....

  public render() {
    return (
      <Provider {...this.stores}>
        <div className="app">
          {this.props.children}
          <Footer />
          <DevTools />
        </div>
      </Provider>
    );
  }

变成......

_createClass(App, [{
    key: "render",
    value: function render() {
        return React.createElement(
            mobx_react_1.Provider,
            this.stores,
            React.createElement(
                "div",
                { className: "app" },
                this.props.children,
                React.createElement(common_1.Footer, null),
                React.createElement(mobx_react_devtools_1.default, null)
            )
        );
    }
}]);

common_1由于某种原因未定义，我无法弄清楚原因。

mobx_react_1.Provider不是，因此似乎只有嵌套组件受到影响。如果我添加“let myVariable =＆lt; Footer /＆gt;”在返回之前，它按预期工作（即使我从未在return语句中引用myVariable！）

我尝试过不同的组件，但总是会遇到同样的错误。我没有收到任何编译错误（除了“DeprecationWarning：loaderUtils.parseQuery（）..”）并且我没有更改我的webpack.config。这些是我的package.json中的依赖项：

知道我在这里缺少什么吗？

嵌套的React.createElement（...）调用中未定义组件引用
