I'm deploying my web app using Laravel Forge and BitBucket. Recently I was coding one part of my website, and I noticed that I made small mistake in CSS, since I couldn't use git push because I'm not finished with coding, I changed that CSS using FTP. So after I finished with development, I tried to git push but I got this error (in Laravel Forge logs):

error: Your local changes to the following files would be overwritten by merge:

After I searched internet I found out that stashing would solve the problem so I changed deploy script to this:

cd /home/forge/default
git stash
git pull origin master
git stash apply stash@{0}
composer install
php artisan migrate --force

But now I receive this error:

*** Please tell me who you are.

Run

  git config --global user.email "you@example.com"
  git config --global user.name "Your Name"

to set your account's default identity.
Omit --global to set the identity only in this repository.

Can someone help me to fix this?
