如何使用react-router重定向到另一个路由？

我正在尝试使用react-router（版本^ 1.0.3）来重定向到另一个视图，这让我很累。

import React from 'react';
import {Router, Route, Link, RouteHandler} from 'react-router';


class HomeSection extends React.Component {

  static contextTypes = {
    router: PropTypes.func.isRequired
  };

  constructor(props, context) {
    super(props, context);
  }

  handleClick = () => {
    console.log('HERE!', this.contextTypes);
    // this.context.location.transitionTo('login');
  };

  render() {
    return (
      <Grid>
        <Row className="text-center">          
          <Col md={12} xs={12}>
            <div className="input-group">
              <span className="input-group-btn">
                <button onClick={this.handleClick} type="button">
                </button>
              </span>
            </div>
          </Col>
        </Row>
      </Grid>
    );
  }
};

HomeSection.contextTypes = {
  location() {
    React.PropTypes.func.isRequired
  }
}

export default HomeSection;

我所需要的只是将使用发送到'/ login'就是这样。

我能做什么？

控制台错误：

未捕获的ReferenceError：未定义PropTypes

用我的路线归档

// LIBRARY
/*eslint-disable no-unused-vars*/
import React from 'react';
/*eslint-enable no-unused-vars*/
import {Route, IndexRoute} from 'react-router';

// COMPONENT
import Application from './components/App/App';
import Contact from './components/ContactSection/Contact';
import HomeSection from './components/HomeSection/HomeSection';
import NotFoundSection from './components/NotFoundSection/NotFoundSection';
import TodoSection from './components/TodoSection/TodoSection';
import LoginForm from './components/LoginForm/LoginForm';
import SignupForm from './components/SignupForm/SignupForm';

export default (
    <Route component={Application} path='/'>
      <IndexRoute component={HomeSection} />
      <Route component={HomeSection} path='home' />
      <Route component={TodoSection} path='todo' />
      <Route component={Contact} path='contact' />
      <Route component={LoginForm} path='login' />
      <Route component={SignupForm} path='signup' />
      <Route component={NotFoundSection} path='*' />
    </Route>
);
