您的班级缺少结尾括号。应该是这样的

.....

class HomeScreen extends React.Component {
  static navigationOptions = {
    title: 'Welcome',
  };

  render() {
    const {navigate} = this.props.navigation;
    return (
      <Button
        title="Go to Jane's profile"
        onPress={() => navigate('Profile', {name: 'Jane'})}
      />
    );
  }
}
