Question

我将styled-components导入了组件。
import styled, { keyframes } from 'styled-components';
错误TypeError: Object(...) is not a function var ThemeContext = createContext();发生了。

我的package.js

"dependencies": {
    "prop-types": "^15.6.0",
    "react": "^16.2.0",
    "react-dom": "^16.2.0",
    "react-redux": "^5.0.6",
    "react-scripts": "1.1.0",
    "redux": "^3.7.2",
    "styled-components": "^4.2.0"
  },

组件代码

import React from 'react';
import PropTypes from 'prop-types';
import styled, { keyframes } from 'styled-components';
import FlyingObjectBase from './FlyingObjectBase';
import FlyingObjectTop from './FlyingObjectTop';

const FlyingObject = props => (
    <g>
      <FlyingObjectBase position={props.position} />
      <FlyingObjectTop position={props.position} />
    </g>
  );

  FlyingObject.propTypes = {
    position: PropTypes.shape({
      x: PropTypes.number.isRequired,
      y: PropTypes.number.isRequired
    }).isRequired,
  };

  export default FlyingObject;

index.js

import React from 'react';
import ReactDOM from 'react-dom';
import { Provider } from 'react-redux';
import { createStore } from 'redux';
import './index.css';
import App from './containers/App';
import reducer from './reducers';
import registerServiceWorker from './registerServiceWorker';



/* eslint-disable no-underscore-dangle */
const store = createStore(
  reducer, /* preloadedState, */
  window.__REDUX_DEVTOOLS_EXTENSION__ && window.__REDUX_DEVTOOLS_EXTENSION__(),
);
/* eslint-enable */

ReactDOM.render(
  <Provider store={store}>
    <App/>
  </Provider>,
  document.getElementById('root'),
);
registerServiceWorker();

解决方案是什么？

非常感谢。
