我有一个新的Ionic项目(“空白”模板)。我已经运行npm install gsap --save
。
这是我的app.module.ts
:
import { BrowserModule } from '@angular/platform-browser';
import { ErrorHandler, NgModule } from '@angular/core';
import { IonicApp, IonicErrorHandler, IonicModule } from 'ionic-angular';
import { SplashScreen } from '@ionic-native/splash-screen';
import { StatusBar } from '@ionic-native/status-bar';
import { MyApp } from './app.component';
import { HomePage } from '../pages/home/home';
import { TweenMax } from "gsap/all";
@NgModule({
declarations: [
MyApp,
HomePage
],
imports: [
BrowserModule,
IonicModule.forRoot(MyApp)
],
bootstrap: [IonicApp],
entryComponents: [
MyApp,
HomePage
],
providers: [
StatusBar,
SplashScreen,
TweenMax,
{provide: ErrorHandler, useClass: IonicErrorHandler}
]
})
export class AppModule {}
这是我的home.ts
:
import { Component } from '@angular/core';
import { NavController } from 'ionic-angular';
import { TweenMax } from "gsap/all";
@Component({
selector: 'page-home',
templateUrl: 'home.html'
})
export class HomePage {
constructor(
public navCtrl: NavController,
public TweenMax: TweenMax
) {
}
ionViewDidLoad(){
TweenMax.from(".logo", .5, {
opacity: 0,
y: -72
});
}
}
但是我的应用出现错误:
Runtime error: Can't resolve all parameters for TweenMax: (?, ?, ?).
这是怎么回事,为什么会出现此错误?我已经尝试了npm page中的所有导入类型,每次都得到相同的结果。
答案 0 :(得分:1)
默认情况下,GSAP TweenMax不提供定义文件。
npm install --save-dev @types/greensock
组件:
declare var TweenMax: any;
