时刻范围插件的打字稿错误

我在Ionic 2应用程序中包含时刻js 和时刻范围插件，如下所示：

I have included moment js and the moment-range plugin in my Ionic 2 app like so:

import * as moment from 'moment';
import 'moment-range';

这个工作正常，我可以同时使用它们，但Typescript给了我以下错误：

This works fine and I can use them both, but Typescript gives me the following error:

Javascript：

let range = moment().range(self.weekStart, self.weekEnd);

打字稿错误：

Error TS2339: Property 'range' does not exist on type 'Moment'.

我已经运行以下命令尝试通过安装打字文件来阻止此错误：

I have ran the following command to try and stop this error by installing a typings file:

typings install moment-range --ambient --save

但它似乎没有任何影响。还有其他我需要做的事情或有没有办法来消除错误？

but it doesn't seem to have had any effect. Is there something else I need to do or is there a way of silencing the error?

感谢您的帮助。
