Apparently ionic-img-viewer was updated to use lettable operators of rxjs 5.5.0 in version 2.9.0.

Your option is to update rxjs version to the current 5.5.2.

npm i rxjs@5.5.2 --save

This may include updating your code to use lettable operators or install an older version of ionic-img-viewer.

npm i ionic-img-viewer@2.8.0 --save
