Question

相关的行在bundle.js中：

exports["default"] = _react.PropTypes.shape({
      subscribe: _react.PropTypes.func.isRequired,
      dispatch: _react.PropTypes.func.isRequired,
      getState: _react.PropTypes.func.isRequired
    });

我刚升级到React 16，并按照此tutorial调整PropTypes。我只有一个引用prop类型的组件，如下所示：

import React, { Component } from 'react';
import PropTypes from 'prop-types';
import { connect } from 'react-redux';

export default function (ComposedComponent) {
    class Authentication extends Component {
        static contextTypes = {
            router: PropTypes.object
        }

我在这里做错了什么？

编辑：这是我的依赖项：

    "chai": "^3.5.0",
    "chai-jquery": "^2.0.0",

    "redux-form": "^7.0.4",
    "redux-thunk": "^2.2.0",
    "webpack": "^3.8.1"
  }

编辑2：即使我注释掉这一行，也会出现同样的错误。但是这条线是整个项目中唯一提到道具类型的地方。是什么给了什么？

static contextTypes = {
            router: PropTypes.object
        }

当前版本的react-spinkit还没有为React 16.0做好准备，因为它仍然使用现在不受支持的React.PropTypes：

最后一次提交是在5月22日。我担心你现在无法升级React。但看起来当前代码已经是两者的混合，并且只有一行可以更改，因此您可以向他们提交带有该更改的拉取请求。
