When running the following lumen new myapp it generates the following error
[ErrorException]
copy(/Users/kev/.composer/cache/files/symfony/translation/75fd13ef

It seems there is a problem in your vendors directory. You can run composer clear-cache and otherwise just delete the vendor directory and run composer install again
composer update laravel/lumen-installer
Composer could not find a composer.json file in /Users/user
To initialize a project, please create a composer.json file as described in the https://getcomposer.org/ "Getting Started" section
@stargatesg1 didn't asked you to update composer but the lumen-installer so that should be the latest version. However you have permission issues from your composer so you need to check what is the user that owns your composer installation, or try using sudo.
@stargatesg1 you probably ran: sudo brew install composer. You can check who owns your composer installation ls -l ~/.composer it will tell you the owner of each directory and file there. So the cache is owned by the root, hence the error.
