我在项目中安装了sweetalert2。但是，在我运行系统后安装它之后，它会产生一些错误。
ERROR in node_modules/@sweetalert2/ngx-sweetalert2/lib/swal.component.d.ts(101,9): error TS1086: An accessor cannot be declared in an ambient context.
node_modules/@sweetalert2/ngx-sweetalert2/lib/swal.component.d.ts(107,9): error TS1086: An accessor cannot be declared in an ambient context.

这是我的angular.json文件规格，

如何解决此问题？
用途：
npm install sweetalert2
这不是问题
