使用 ng2-pdf-viewer 和 angular-cli

Question

我正在尝试将 ng2-pdf-viewer 添加到我的 angular2 项目中，但我在使用 Angular-CLI 设置它时遇到问题，指南说我应该将映射添加到 systemjs 但 angular-cli 没有'现在不使用 systemjs。 我尝试在 angular-cli.json 中添加 lib 的路径，但它给了我同样的错误。

Uncaught Error: Unexpected value 'PdfViewerComponent' declared by the module 'AppModule'

这是我从组件中得到的错误，该组件使用 pdfjs-dist 并且它不包含任何 ts 文件，并且由于指南说我不能使用 systemjs，因此我需要一些帮助。

angular-cli.json:

 {
  "project": {
    "version": "1.0.0-beta.17",
    "name": "ng_pdf_app"
  },

    }

ng2-pdf-viewer

Answer 1

查看 How to integrate third party libraries 上的 Angular-CLI 文档

你只需要在angular-cli.json文件的scripts对象中包含相应的JS文件。

希望这会有所帮助！
