I ran the 'bundle install' and this error occurred. So to fix the bug of the project, I ran 'gem install mysql2 '0.4.8'' command in console but I can't fix it.
This ruby on rails uses Spree framework.

I ran 'bundle install' but I can't success this command because of this error.
I think you missing dev library of mysql:
On ubuntu
sudo apt-get install libmysqlclient-dev
On Red Hat/CentOS and other distributions using yum:
sudo yum install mysql-devel
On Mac OS X with Homebrew:
brew install mysql
