如何解决由于提供'@ ionic-native/AppVersion'或'.../ngx'并在调用任何AppVersion方法时出现异常而导致的问题? [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本机插件( https://ionicframework.com /docs/native/app-version#usage ).
尝试将其提供给我的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" ...
我认为可能是从AppVersion的Ionic 4/最新版本开始，我需要遵循以下说明: https://ionicframework.com/docs/native/#Add_Plugins_to_Your_App_Module ，其中说要为插件提供到app.module.ts中，并具有如下所示的导入方式:
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 :
import AppVersion from '@ionic-native/AppVersion/ngx'.
代码编译.完美的.但是可悲的是，在运行时我遇到了一个错误:
The code compile. Perfect. But sadly at runtime i have an error which say:
TypeError: Object(__WEBPACK_IMPORTED_MODULE_1__ionic_native_core__["cordova"]) is not a function. (In 'Object(__WEBPACK_IMPORTED_MODULE_1__ionic_native_core__["cordova"])(this, "getPackageName", {}, arguments)', 'Object(__WEBPACK_IMPORTED_MODULE_1__ionic_native_core__["cordova"])' is an instance of Object)
getPackageName — index.js:28...
TypeError: Object(__WEBPACK_IMPORTED_MODULE_1__ionic_native_core__["cordova"]) is not a function. (In 'Object(__WEBPACK_IMPORTED_MODULE_1__ionic_native_core__["cordova"])(this, "getPackageName", {}, arguments)', 'Object(__WEBPACK_IMPORTED_MODULE_1__ionic_native_core__["cordova"])' is an instance of Object)
getPackageName — index.js:28...
因此，对于这个耗时的问题，我的解决方案是获取适用于另一个项目的AppVersion的保留版本:
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到我的app.module.ts(import AppVersion from '@ionic-native/AppVersion')中，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App版本插件，要先删除该插件，然后再安装该插件，例如:
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
