TypeError:员工。查找不是meteor withTracker的函数

首先使用createContainer订阅数据,但它引发了一个名为:

Uncaught TypeError: CreateContainer is not a function 

react-meteor-data: React higher-order component for reactively tracking Meteor data 

Warning - createContainer was deprecated in react-meteor-data@0.2.13. Use withTracker instead 

然后更改为withTracker,但出现错误:

Uncaught TypeError: Employees.find is not a function

Employee\u列表。js公司

import React from 'react';
import Employees from '../../imports/collections/employees';
import { withTracker } from 'meteor/react-meteor-data';

const EmployeeList = (props) => {
    console.log(props);
    return(
        <div>
            <div className = "employee-list">
                Employee list
            </div>
        </div>
    )
}

export default withTracker ( () => {

    const handle = Meteor.subscribe('employees');
    //return { employeesd: Employees.find({}).fetch() };
    return {
        listLoading: !handle.ready(),
        tasks: Employees.find({}).fetch(),
      };
})( EmployeeList );

员工是我的mongodb集合

员工。js公司

import { Mongo } from 'meteor/mongo';    
export const Employees = new Mongo.Collection('employees');
