几天来,我一直在尝试使推送通知在ionic中工作,到目前为止,我已经完成了7篇教程,但是一旦我到达了开始测试的地步,它们中的每一个都将失败! 。仅仅是我还是所有这些教程都过时了?
到目前为止,我已经尝试过以下教程:
对于这些教程中的每一个,我都会碰到一堆关于Push模块的消息,一种或另一种方式是我不断遇到这些相同的错误,不同的教程之间有一些很小的变化,但总的来说,这些都是相同的错误,下面的内容来自我遵循的最新教程(luisjordan之一):
From the app.component.ts file, i get an error for the constructor:
----------------------
typescript: C:/Users/***/Documents/ionic/push-luisjordan/src/app/app.component.ts, line: 15
Cannot find name 'Push'.
L15: constructor (platform : Platform, statusBar : StatusBar, splashScreen : SplashScreen, private push : Push) {
L16: platform.ready().then(() => {
----------------------
And from app.module.ts file, i get an error for the providers:
----------------------
typescript: C:/Users/***/Documents/ionic/push-luisjordan/src/app/app.module.ts, line: 12

为防止将此问题变成更大的文字墙,我制作了以下pastebin页面,其中包含上面发布的相同错误,但更重要的是,它还包含app.component.ts和app.module的代码.ts

有人知道什么可能是错的吗?我已经读了好几天了,但我仍然不知道我可能会缺少什么?每次遇到同一个离子不会接受推送模块的问题...:(

似乎Ionic团队最近对其原生插件进行了更改。
您似乎已安装了ionic 4支持的插件(版本> = 5.0.0)。 由于您使用的是ionic 3,请卸载插件并安装4.20.0版本。
npm uninstall @ionic-native/push
然后
npm i -s @ionic-native/push@4.20.0
