webpack打包vue项目 keep-alive不生效

路由代码：

module.exports = (file: string) => {
  ‘use strict‘;

  return () => import(`@/views/${file}`);
};
const getComponent = require(`./import_${process.env.NODE_ENV}`);
{
    path: ‘/customers‘,
    name: ‘Customers‘,
    component: getComponent(‘customers/index‘),
    permission: true,
    meta: { key: ‘Customers‘ },
    children: [
      {
        path: ‘baseInfo‘,
        name: ‘Base Info‘,
        component: getComponent(‘customers/baseInfo/index‘),
        permission: true,
        meta: { key: ‘BaseInfo‘ },
      },
    ],
  },
页面代码：

import { Component, Vue } from ‘vue-property-decorator‘;

@Component
export default class Components extends Vue {
  render() {
    const { keepList } = this.$store.state.app;
    return (
      <keep-alive max={10} include={keepList}>
        <router-view />
      </keep-alive>
    );
  }
}

@Component{
    name: ‘componentName‘
}
export default class Components extends Vue {}
