如何使用ngx-pagination对ionic4应用程序中的数据进行分页？

Question

我遵循这个页面(https://www.npmjs.com/package/ngx-pagination)的命令将ngx-pagination放入我的ionic应用程序中。我得到这个error.It似乎ngx-pagination包没有安装successfully.Is，还有其他解决方案吗？

看起来你正在懒惰地加载菜单页面。在这种情况下，您必须在menu.module.ts中导入NgxPaginationModule

注意:请确保在导入NgxPaginationModule的同一模块中声明了组件
