I tried updating a Laravel project I\'m working on today using composer update
But it hung on Updating dependencies (including require-dev)
I found this in another article, I found that doing the following below worked. It seemed to be a cache/download issue into the composer packages cache.
composer update -vvv
Then doing the following: Add or edit your composer file to have these settings.
"repositories": [
{
"type": "composer",
"url": "https://packagist.org"
},
{ "packagist": false }
]
