Gem files will remain installed in /usr/local/rvm/gems/ruby-1.9.3-p194/gems/mysql-2.8.1 for inspection.
Results logged to /usr/local/rvm/gems/ruby-1.9.3-p194/gems/mysql-2.8.1/ext/mysql_api/gem_make.out
An error occured while installing mysql (2.8.1), and Bundler cannot continue.
Make sure that `gem install mysql -v '2.8.1'` succeeds before bundling.


I have searched in google and came to see its missing some required libraries i.e 'libmysqlclient15-dev'

To install the 'libmysqlclient15-dev' library run the below command,

> sudo apt-get install libmysqlclient15-dev


Now it will solve the above issue.

Thank You,
Uma Mahesh.
