Ionic 4 Camera/ActionSheet对象(...)不是一个功能

Question

我正在尝试在Ionic 4中使用Camera Plugin,当服务启动时没有错误,在浏览器控制台中出现此错误:

我删除文件夹node_modules并重新安装它,但无法解决此问题.

npm安装

使用ActionSheet我有同样的错误.

编辑:当我试图编译它!(使用ActionSheet)

--verbose:

ionic:cli-framework:utils:process onBeforeExit handler: process.exit received +0ms
  ionic:cli-framework:utils:process onBeforeExit handler: running 1 queued functions +6ms
  ionic:cli-framework:utils:process error while killing process tree for 8104: { Error: Command failed: taskkill /pid 8104 /T /F ERROR: no se encontr? el proceso "8104".  at ChildProcess.exithandler (child_process.js:275:12) at emitTwo (events.js:126:13) at ChildProcess.emit (events.js:214:7) at maybeClose (internal/child_process.js:925:16) at Process.ChildProcess._handle.onexit (internal/child_process.js:209:5) killed: false, code: 128, signal: null, cmd: 'taskkill /pid 8104 /T /F' } +60ms
net.js:714
    throw new TypeError(
    ^

仅当某些TS文件具有导入时才会出现此错误.如果使用它并不重要.

从'@ ionic-native/action-sheet'导入{ActionSheet,ActionSheetOptions};

我解决了!

我需要安装@ 5.0.0-beta.17软件包.

npm i -s @ ionic-native/camera @ 5.0.0-beta.17

npm i -s @ ionic-native/action-sheet @ 5.0.0-beta.17

然后,我可以使用它:

import { Camera, CameraOptions } from '@ionic-native/camera/ngx'; import { ActionSheet, ActionSheetOptions } from '@ionic-native/action-sheet/ngx';
