如何安装React-Toastr

Question

我安装了react-toastr并集成了示例代码。

import React from 'react'
import { ToastContainer } from 'react-toastr';
class Notifier extends React.Component
{
  updateNotify()
  {
    this.refs.container.info('hola el mundo');
  }
  render()
  {
    return(
      <ToastContainer ref="container"
      className="toast-top-right" />
    );
  }
}

当我在容器上调用info（）时，消息会弹出，但就像页面顶部的纯文本一样，而不是右上角的样式框。该消息也永远不会消失。因此，似乎缺少CSS和JavaScript组件。

我做错什么了？为什么在Linux下安装fsevents时会有那些警告？如果有问题，我正在使用反应15。我降级为react-toastr 2.9.5版，但没有什么不同。

$ npm install --save react-toastr
myApp@0.3.1 /home/myApp
??? react-toastr@3.0.0
  ??? babel-runtime@6.26.0
    ??? core-js@2.5.3
    ??? regenerator-runtime@0.11.1
