A component doesn't import


I cannot find out why this happened all of a sudden. I have not changed anything, and this was working.

Meteor, React, Ant-Design. Please help!

The error is: ReferenceError: Layout is not defined

Code is:

import React from 'react';
import Blaze from 'meteor/gadicc:blaze-react-component';
import { Link } from 'react-router-dom';
import { Layout, Menu } from 'antd';
const { Header, Content, Footer } = Layout;

class LayoutContainer extends React.Component {
  render() {

    const { match, children } = this.props;
    const pathname = match.location.pathname;

    return (
      <Layout className="layout">
        <Header style={{backgroundColor: '#fff'}}>
            style={{ lineHeight: '64px', float: 'right' }}
            <Menu.Item key={'/'}>
              <Link to="/">Home</Link>
            <Menu.Item key={'/create-a-gathering'}>
              <Link to="/create-a-gathering">Create</Link>
          <div className="logo" />
          <Blaze template="loginButtons" />
        <Content style={{ marginTop: 20 }}>
        <Footer style={{ textAlign: 'center' }}>


export default LayoutContainer;
