当webpack从node_modules加载'ng2-uploader'时，Typescript没有发出输出

我有一个用Webpack 2.1包装的Angular2项目.~ . 我从npm软件包安装了ng2-uploader，它现在位于node_modules下面 . 现在，当我启动应用程序时，我收到此错误：

“Typescript在Object.loader上没有为（..path \ ng-file-select.ts）发出输出（path \ node_modules \ ts-loader ..）”“Typescript没有为（.path \ ng2-uploader）发出任何输出.ts）at Object.loader（path \ node_modules \ ts-loader ..）“”Typescript在Object.loader（path \ node_modules \ ts-loader）中没有为（..path \ ng-file-drop.ts）发出任何输出..）”

这是打字稿加载器的问题吗？

Webpack正在将ts文件编译成js，错误是从ng2-uploader的index.js的这一部分中获取的：

if (outputText == null)
        throw new Error("Typescript emitted no output for " + filePath);

这是我的tsconfig.json：

  "compilerOptions": {
    "baseUrl": ".",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "lib": [
      "dom",

有什么问题，我该如何解决这个问题？
