React-select 组件不工作

Question

我正在尝试使用 react-select component. I have the normal version working absolutely fine, but when I add try to use this async example from the project documentation:

的异步版本

var Select = require('react-select');

var getOptions = function(input, callback) {
    setTimeout(function() {
        callback(null, {
            options: [
                { value: 'one', label: 'One' },
                { value: 'two', label: 'Two' }
            ],
            // CAREFUL! Only set this to true when there are no more options,
            // or more specific queries will not be sent to the server.
            complete: true
        });
    }, 500);
};

<Select.Async
    name="form-field-name"
    loadOptions={getOptions}
/>

我在控制台中收到此错误：

Warning: React.createElement: type should not be null, undefined, boolean, or number. It should be a string (for DOM elements) or a ReactClass (for composite components). Check the render method of OrderHeaderEdit.

我一直在尝试将其调试到 React 代码中，但我终其一生都无法弄清楚发生了什么。

这是我的完整组件代码，用于具有上述异步 select 组件的组件。此控件在 Meteor 1.3 应用程序中运行：

import React from 'react';
import Select from 'react-select';

const OrderHeaderEdit = React.createClass({

    getOptions(input, callback) {
        setTimeout(function () {
            callback(null, {
                options: [
                    { value: 'one', label: 'One' },
                    { value: 'two', label: 'Two' }
                ],
                // CAREFUL! Only set this to true when there are no more options,
                // or more specific queries will not be sent to the server.
                complete: true
            });
        }, 500);
    },

    render() {
        console.log("OrderHeaderEdit props: ", this.props);

        var getOptions = function (input, callback) {
            setTimeout(function () {
                callback(null, {
                    options: [
                        { value: 'one', label: 'One' },
                        { value: 'two', label: 'Two' }
                    ],
                    // CAREFUL! Only set this to true when there are no more options,
                    // or more specific queries will not be sent to the server.
                    complete: true
                });
            }, 500);
        };

        return (
            <div>

                <Select.Async
                    name="form-field-name"
                    loadOptions={getOptions}
                />

            </div>
        );
    }
});

export default OrderHeaderEdit;

问题似乎出在 Select.Async 行中的“.Async”扩展名，这会不会混淆 Meteor？

Answer 1

我找出问题所在：从 npm 安装当前安装版本 0.9.x，但是文档和示例已经更新到版本 1.0.0-betaX，其中有重大更改。

所以，Select.Async 确实是问题所在，该语法仅从 1.0 开始存在，作为 react-select github 存储库中的 discussed in this list of breaking changes in 1.0.0。更新我的代码以使用 1.0.0-beta9 版本解决了这个问题。
