我和我的团队正在使用ngx-bootstrap datepicker。 我们的应用正在使用“角度/升级”：“ ^ 5.2.2”， 问题是-导航箭头不起作用，单击时没有任何反应。
依赖项：
uirouter/angularjs": "^1.0.14",
angular/animations": "^5.0.0",
angular/common": "^5.0.0",
angular/compiler": "^5.0.0",
angular/core": "^5.0.0",
angular/forms": "^5.0.0",
angular/http": "^5.0.0",
angular/platform-browser": "^5.0.0",
angular/platform-browser-dynamic": "^5.0.0",
angular/router": "^5.0.0",
angular/upgrade": "^5.2.2",
"core-js": "^2.4.1",
"rxjs": "^5.5.2",
"zone.js": "^0.8.14",
"ngx-bootstrap": "^2.0.4"
任何想法为何？或类似问题？
