RuntimeException The Zip PHP extension is not installed
Try type into the command line:
sudo apt-get install php7.0-zip
Verify from any route with:
dd(get_loaded_extensions());
This worked for me, good luck.
for php 7.0
sudo apt-get install php7.0-zipfor php 7.1
sudo apt-get install php7.1-zipand so on!
I got the same issue and tried to install the extension with the command sudo apt install php7.0-zip but still got the same error. I finally solved it with sudo apt install php-zip
