为了在angualr4项目中导入jquery,我执行以下操作：
npm install --save jquery npm install --save-dev @types/jquery
在app.component.ts中
import $from 'jquery'; or import * as $from 'jquery';
当运行“ng serve”时
我有这些错误
ERROR in C:/jquery-angular/jqueryintegration/node_modules/@types/jquery/index.d.ts (47,40): ',' expected.

}
“导入”加载默认的javascript文件还是必须以某种方式配置？
尝试这个
从’jquery / dist / jquery.min.js’导入*为$;
