如何解决由于提供“@ionic-native/AppVersion"或“.../ngx"而导致的问题，并且在调用 AppVersion 的任何方法时出现异常? [英] How to fix problem due to providing '@ionic-native/AppVersion' or '.../ngx' and having exception when calling any methods of AppVersion?
问题描述
我添加了 AppVersion Ionic 原生插件(https://ionicframework.com/docs/native/app-version#usage).尝试将其提供到我的 app.module.ts 后，我在编译时出现错误，例如AppVersion 不存在提供程序"...
I've added the AppVersion Ionic native plugin (https://ionicframework.com/docs/native/app-version#usage).
After try to provide it into my app.module.ts i've an error at compilation like "No provider exists for AppVersion" ...
我认为可能来自 Ionic 4/最新版本的 AppVersion，我需要遵循以下说明:https://ionicframework.com/docs/native/#Add_Plugins_to_Your_App_Module 说要通过这样的导入将插件提供到 app.module.ts 中:
I thinking that maybe from Ionic 4/recent version of AppVersion, i need to follow this instructions : https://ionicframework.com/docs/native/#Add_Plugins_to_Your_App_Module which say to provide the plugin into the app.module.ts with a import like this :
从@ionic-native/AppVersion/ngx"导入 AppVersion.
代码编译.完美的.但遗憾的是在运行时我有一个错误说:
The code compile. Perfect. But sadly at runtime i have an error which say:
TypeError: Object(__WEBPACK_IMPORTED_MODULE_1__ionic_native_core__["cordova"]) 不是函数.(在 'Object(__WEBPACK_IMPORTED_MODULE_1__ionic_native_core__["cordova"])(this, "getPackageName", {}, arguments)' 中，'Object(__WEBPACK_IMPORTED_MODULE_1__ionic_native_core__["cordova"])' 是 Object 的一个实例)getPackageName — index.js:28...
所以我对这个耗时问题的解决方案是获取 AppVersion 的保留版本，该版本适用于另一个项目:
So my solution to this time-consuming problem, was to take an hold version of the AppVersion, which works on another project :
package.json:
...
"@ionic-native/app-version": "^4.18.0",
...
"cordova-plugin-app-version": "0.1.9",
...
有了这个，我可以正常地将插件导入我的app.module.ts(import AppVersion from '@ionic-native/AppVersion')，一切正常.
With this, i can import normally the plugin into my app.module.ts (import AppVersion from '@ionic-native/AppVersion') and everything is ok.

推荐答案
降级您当前的应用程序版本插件，首先删除此插件，然后再次安装此插件，如::
Downgrade your current App version plugin, to do that remove this plugin first after that install this plugin again like::
1) ionic cordova plugin add cordova-plugin-app-version
2) npm i @ionic-native/app-version@4.8.0
