     recognizeImage() {
    Tesseract.recognize(this.selectedImage)
    .progress(message => {
      if (message.status === 'recognizing text')
      this.progress.set(message.progress);
    })

    <ion-card-content>
      {{ imageText }}
    </ion-card-content>
  </ion-card>
</ion-content>

The problem is your Angular's version doesn't compatible with ngx-progressbar's version. You can upgrade your angular or downgrade ngx-progressbar.

In my project I downgraded ngx-progressbar to version 4. For example: npm install @ngx-progressbar/core@v4.3.0

You can check the documentation in Git for more infomations. There are 2 docs 1 supports Angular >= 5 and another for Angular 2.x & 4.x
