错误：无法调用类型缺少调用签名的表达式。类型 ' 没有兼容的 c ll 签名

Question

我正在尝试在我的 Angular 项目中使用 https://github.com/mapbox/polylabel，当我尝试运行 ng 服务器时，构建失败并出现以下错误

error TS2349: Cannot invoke an expres ion whose type lacks a call signature. Type node_modules/@types/polylabel/index"'has no compatible c ll signatures.

下面是 index.ts 的代码

    // Type definitions for polylabel 1.0
   // Project: https://github.com/mapbox/polylabel

    /**
     * Polylabel returns the pole of inaccessibility coordinate in [x, y] format.
     *
     * @param polygon - Given polygon coordinates in GeoJSON-like format
     * @param precision - Precision (1.0 by default)
     * @param debug - Debugging for Console
     * @example
     * var p = polylabel(polygon, 1.0);
     */
    declare function polylabel(polygon: number[][][], precision?: number, debug?: boolean): number[];
    declare namespace polylabel {}
    export default polylabel;

显然我没有全局安装 polylabel。执行npm install polylabel 解决了这个问题。
