这是我们npm install在服务器上遇到的一个问题,它为node_modules加载了一组新的版本.

我们有一个看起来像的模块

export default class DemoComponent extend React.Component {
  render() {
    return(
      <h1>Hello</h1>
    );
  }
}

export default connect(
  mapStateToProps,
  { ... }
)(DemoComponent);

在我们npm install加载新版本的开发依赖项之前,它曾经工作正常.

错误日志:
