这是我的TS文件

import * as jsPDF from 'jspdf';
import * as html2canvas from 'html2canvas';


  public backupCodesDownload() {
    const doc = new jsPDF();

    const specialElementHandlers = {
      '#editor': function (element, renderer) {
        return true;
      }
    };

    const content = this.downloadPanelContent.nativeElement;

    doc.addHTML(content.innerHTML, 0, 0, {
      'width': 100, // max width of content on PDF
      'elementHandlers': specialElementHandlers
    },
      function save() { doc.save('BackupCodes.pdf'); window.open(doc.output('bloburl')); }, 0);
  }

包.Json

 "dependencies": {
    "html2canvas": "^1.0.0-rc.5",
    "jspdf": "^1.5.3"
}

"scripts": [
              "./node_modules/jspdf/dist/jspdf.min.js"
            ]

我也将脚本直接添加到Index.html页面,但遇到了同样的问题。
