Ionic 3: CameraPreview.startCamera returns plugin_not_installed

When I invoke the startCamera the promise returns an error with the message “plugin_not_installed”.

I installed it using: $ ionic cordova:plugin add cordova-plugin-camera-preview

But i noticed that the docs for native only have “Camera” and not “CameraPreview”.

Any thoughts? Thank you very much.

        private cameraPreview: CameraPreview) {


    checkPermissions() {
        this.diagnostic.isCameraAuthorized().then((authorized) => {
            if (authorized) {
                console.log('starting Camera');
            else {
                this.diagnostic.requestCameraAuthorization().then((status) => {
                    if (status == this.diagnostic.permissionStatus.GRANTED)
                    else {

    initializePreview() {

        // to the width and height of the app's window
        var cameraPreviewOpts: CameraPreviewOptions = {

            previewDrag: true,
            toBack: true,
            alpha: 1

        var that = this;

        this.cameraPreview.startCamera(cameraPreviewOpts).then(function () {
                    message: "Starting Camera: OK",
                    position: "bottom",
                    duration: 5000
        }, function (error) {
            console.log('error', error);

Cordova CLI: 6.5.0
Ionic Framework Version: 3.0.0
Ionic CLI Version: 3.0.0-beta.5
ios-deploy version: Not installed
ios-sim version: Not installed
OS: Windows 10
Node Version: v6.9.4
Xcode version: Not installed

Also tried the platform.ready() aproach, with no success.

I got the same problem and I did this:
ionic plugin rm --save cordova-plugin-camera-preview
ionic plugin add --save

There is a Ionic Native thingie for this plugin (in beta though) that might help:

I updated the cli, did those steps and also:
$ npm install --save @ionic-native/camera-preview

Got it to work after that.

I know this is a bit late, but I have tried all of the above but with no luck… :frowning:

I keep on getting “plugin_not_installed” error and this is really upsetting me since my app will be based around this.
