On a new installation of Laravel and Voyager, I cannot crop images; however, my other installation 2 months before, cropping was fine.
New installation
Same here. Also I want to add this error in console:
app.js:42 Uncaught ReferenceError: Cropper is not defined
at HTMLDivElement.(app.js:42)
at HTMLDivElement.dispatch (app.js:24)

Can you guys try to force republish the voyager assets (specifically app.js)? Should be something to the effect of artisan vendor:publish --tag="voyager_assets" --force. Also, please clear your browser cache to make sure it's not cached somewhere.
I have republished and cancelled the cache without success.
I have the same issue!
Voyager v1.0.7
Laravel 5.5 (latest)
php 7.0
same problem:
ReferenceError: Cropper is not defined app.js:42:12284
new install today v1.09
using server.php
On my app ( v1.0.7 ) it doesn't work since i had install this version of voyager, it is probably some bug.
I am facing the same issue on v1.0.10, I did what @fletch3555 mentioned and the problem persist.
I've found a turnaround by manually copy&paste the content from https://github.com/fengyuanchen/cropperjs/blob/master/dist/cropper.min.js at the begining of the public/vendor/tcg/voyager/assets/js/app.js

Maybe app.js is getting corrupted?
Same problem as well on fresh install !
