如何在Angular 7中使用jsPDF？获取jspdf\网页包\导入的模块\ 2 \ jspdf不是构造函数错误

我正在尝试在我的Angular 7.1.3项目中使用jsPDF

My package.json如下（相关部分）：

"dependencies": {
    "@angular/animations": "~7.1.0",
    "@angular/common": "~7.1.0",
    "@angular/compiler": "~7.1.0",
    "@angular/core": "~7.1.0",
    "@angular/forms": "~7.1.0",
    "@angular/platform-browser": "~7.1.0",
    "@angular/platform-browser-dynamic": "~7.1.0",
    "@angular/router": "~7.1.0",
    "core-js": "^2.5.4",
    "jspdf": "^1.5.3",
    "rxjs": "~6.3.3",
    "tslib": "^1.9.0",
    "zone.js": "~0.8.26"
  },

import { Component, ViewChild, ElementRef } from '@angular/core';
import { jsPDF } from 'jspdf';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  title = 'angular-html-pdf';

  @ViewChild('pdfTable') pdfTable: ElementRef;


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

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

    const pdfTable = this.pdfTable.nativeElement;

    doc.fromHTML(pdfTable.innerHTML, 15, 15, {
      width: 190,
      'elementHandlers': specialElementHandlers
    });

    doc.save('tableToPdf.pdf');
  }
}

我的组件：

"dependencies": {
    "@angular/animations": "~7.1.0",
    "@angular/common": "~7.1.0",
    "@angular/compiler": "~7.1.0",
    "@angular/core": "~7.1.0",
    "@angular/forms": "~7.1.0",
    "@angular/platform-browser": "~7.1.0",
    "@angular/platform-browser-dynamic": "~7.1.0",
    "@angular/router": "~7.1.0",
    "core-js": "^2.5.4",
    "jspdf": "^1.5.3",
    "rxjs": "~6.3.3",
    "tslib": "^1.9.0",
    "zone.js": "~0.8.26"
  },

import { Component, ViewChild, ElementRef } from '@angular/core';
import { jsPDF } from 'jspdf';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  title = 'angular-html-pdf';

  @ViewChild('pdfTable') pdfTable: ElementRef;


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

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

    const pdfTable = this.pdfTable.nativeElement;

    doc.fromHTML(pdfTable.innerHTML, 15, 15, {
      width: 190,
      'elementHandlers': specialElementHandlers
    });

    doc.save('tableToPdf.pdf');
  }
}

没有编译时错误，但运行downloadAsPDF（）函数会给出：

---

错误类型错误：“jspdf\uuu网页包\u导入的\u模块\uuuu.jspdf不是构造函数”

错误是由导入语句引起的

---

从'jsPDF'导入{jsPDF}

改为：

从“jsPDF”导入jsPDF
从“jsPDF”导入{jsPDF}在角度9中工作得非常好。尝试从“jsPDF”导入*为jsPDF
我使用angular 10，这是有效的：
const doc=new jspdf.jspdf（）
