SSR problems

### Description

Hello,
I was trying to use ElementUI with `react-express-views` and when I'm trying to use Button (or any other component) I get an error

### Reproduce Steps

1. Set up express server with `express-react-views`
```js
const express = require('express');
const consoleUtil = require('../util/consoleUtil.js');

const app = express();

app.set('views', __dirname + '/views');
app.set('view-engine', 'jsx');
app.engine('jsx', require('express-react-views').createEngine());

const router = express.Router();
app.use('/', router);

router.get('/', (req, res, next) => {
res.render('main/test.jsx', {
test: 'test text',
title: 'test title'
});
});

app.listen(8080, () => {
consoleUtil.log('Webserver running...')
});
```
2. Make `test.jsx` template in `views` folder
```js
const React = require('react');
const ElementUI = require('element-react');

class TestLayout extends React.Component {
render() {
return (






Hello



);
}
}

module.exports = TestLayout;
```
3. Run the server and go to `localhost:8080`
