我正在尝试在打字稿中导入jspdf的类型定义，但不知何故。我收到此错误（未找到）：

这是我的index.php，在这里我使用requireJS加载我的类（JSPDFControl.js），然后导入jspdf脚本：
<html>
<head>
<script type="text/javascript" src="/PetshopSanvictorPHP/node_modules/jspdf/dist/jspdf.debug.js"></script>
<script data-main="/PetshopSanvictorPHP/script/js/control/JSPDFControl.js" src="/PetshopSanvictorPHP/node_modules/requirejs/require.js"></script>
</head>
<body>
</body>
</html>
这是我的Typescript类（JSPDFControl.ts），我尝试在其中导入jspdf @type：
//JSPDFControl.ts
import { jsPDF } from "jspdf"; //Here is the big question
export class JSPDFControl {
public static newDocument() {
var doc = new jsPDF();
doc.text('Hello world!', 10, 10)
doc.save('test.pdf')
}
}
JSPDFControl.newDocument();
翻译版本（JSPDFControl.js）
//JSPDFControl.js
define(["require", "exports", "jspdf"], function (require, exports, jspdf_1) {
"use strict";
Object.defineProperty(exports, "__esModule", { value: true });
class JSPDFControl {
static newDocument() {
var doc = new jspdf_1.jsPDF();
doc.text('Hello world!', 10, 10);
doc.save('test.pdf');
}
}
exports.JSPDFControl = JSPDFControl;
JSPDFControl.newDocument();
});
这是我的tsconfig.json：
{
"compilerOptions": {
"target": "es2020",
"module": "amd",
"allowJs": true,
"noEmitOnError": false,
"outDir": "../js",
"watch": true
}
}
我已经通过npm npm install jspdf --save安装了jspdf
并也安装在@types中：npm install @types/jspdf --save-dev
我导出了@ types / jspdf / index.d.ts中的类：

当我尝试导入任何类型定义时，会发生此错误，好像编译器从运行时目录（http://localhost/PetshopSanvictorPHP/script/js/control/jspdf.js）中导入@type。
当我删除导入时，脚本可以正常运行，但是IDE（可视化工作室）无法识别（找不到名称“ jsPDF”）。
如何解决此问题，正确导入，使IDE识别jsPDF并同时执行脚本？
