Пользовательский интерфейс материала v1 - SwipeableDrawer: недопустимый тип элемента

Я реализовал Перелистываемый и получаю печально известную ошибку:

 Element type is invalid: expected a string (for built-in components)
 or a class/function (for composite components) but got: undefined.
 You likely forgot to export your component from the file it's defined in.

Check the render method of `SwipeableDrawer`.

Думаю, я установил все необходимые реквизиты, как это сделано в демонстрации. Вот реализация.

import React from 'react'
import PropTypes from 'prop-types'
import { withStyles } from '@material-ui/core/styles'
import SwipeableDrawer from '@material-ui/core/SwipeableDrawer'
import IconButton from '@material-ui/core/IconButton'
import MenuIcon from '@material-ui/icons/Menu'
import List from '@material-ui/core/List'
import Divider from '@material-ui/core/Divider'
import { drawerListItems } from './DrawerListItems'

const styles = {
    list: {
        width: 250,
    },
    fullList: {
        width: 'auto',
    },
};

class SwipeableTemporaryDrawer extends React.Component {
    state = {
        left: false,
    };

    toggleDrawer = (open) => () => {
        this.setState({
            left: open
        });
    };

    render() {
        const { classes } = this.props;

        const sideList = (
            <div className = {classes.list}>
                <List>{drawerListItems}</List>
                <Divider />
                <List>{drawerListItems}</List>
            </div>
        );

        return (
            <div>
                <IconButton className = {classes.menuButton} color = "inherit" onClick = {this.toggleDrawer(true)}>
                    <MenuIcon />
                </IconButton>
                <SwipeableDrawer
                    open = {this.state.left}
                    onClose = {this.toggleDrawer(false)}
                    onOpen = {this.toggleDrawer(true)}
                >
                    <div
                        tabIndex = {0}
                        role = "button"
                        onClick = {this.toggleDrawer( false)}
                        onKeyDown = {this.toggleDrawer(false)}
                    >
                        {sideList}
                    </div>
                </SwipeableDrawer>
            </div>
        );
    }
}

SwipeableTemporaryDrawer.propTypes = {
    classes: PropTypes.object.isRequired,
};

export default withStyles(styles)(SwipeableTemporaryDrawer);
