ionic-framework - 数字输入不反映

Question

我正在使用 Ionic 3 和 Angular 5 并尝试使用如下：

<ion-input type="number"><ion-input>

所以它应该像这样反映：

但是当我使用上面的代码行时，它会像正常输入一样反映并且仅在应用程序中看不到向上和向下箭头但是当我创建其他离子应用程序并使用完全相同的行时，它的工作不知道为什么。我使用的依赖项如下：

"@angular/common": "5.0.3",
"@angular/compiler": "5.0.3",
"@angular/compiler-cli": "5.0.3",
"@angular/core": "5.0.3",
"@angular/forms": "5.0.3",
"@angular/http": "5.0.3",
"@angular/platform-browser": "5.0.3",
"@angular/platform-browser-dynamic": "5.0.3",
"@ionic-native/core": "4.4.0",
"@ionic-native/date-picker": "^4.5.3",
"@ionic-native/splash-screen": "4.4.0",
"@ionic-native/sqlite": "^4.5.3",
"@ionic-native/status-bar": "4.4.0",
"@ionic/storage": "2.1.3",
"ionic-angular": "3.9.2",
"ionic-native": "^2.9.0",

任何人都可以建议我该怎么做？
