Error after running bin/magento setup:upgrade

Hi @Joe and welcome,

This error message doesn’t seem to give much (if anything) away. My default response for a scenario like this would be:

1 Verify Folder/File Permissions are correct

Ref: How to diagnose and fix Ownerships and Permission issues

2 Manually clear caches

Run from the Magento root directory

rm -rf var/cache/* var/page_cache/* generated/code/*

Otherwise, it’s possible that the module you’re attempting to install is at fault.
