在 angular 2/4 中使用 UMD 库

use UMD library in angular 2/4

我有库(Tus.io) thats compiled to UMD。我的 Angular2/4 项目需要它。当我用 npm 安装它时(npm install tus-js-client ) 并导入它 (var tus = require("tus-js-client"); ) 我得到的错误是:

Failed to compile.
/home/***/src/app/manageVideos/Partials/add.component.ts (8,17): 
Module '../../../../node_modules/tus-js-client/dist/tus.js' 
was resolved to '/home/***/node_modules/tus-js-client/dist/tus.js', 
but '--allowJs' is not set.
/home/***/src/app/manageVideos/Partials/add.component.ts (9,11): Cannot find name 'require'.

解决您问题的最简单方法是安装 TypeScript 声明:

npm install @types/tus-js-client --save-dev

并像这样导入它:

import * as tus from "tus-js-client";
