error while running bundle install

Installing mysql2 (0.3.11) with native extensions

Make sure that `gem install mysql2 -v '0.3.11'` succeeds before bundling.

when i run Make sure that gem install mysql2 -v '0.3.11'.I still get the same error.

which OS are you using?

anyway if you are using ubuntu, from this https://github.com/brianmario/mysql2/issues/8 run:

sudo apt-get install mysql-client libmysqlclient-dev

Otherwise for Mac users,(use brew to install) check this Link, or run:

brew install mysql

then

sudo gem install mysql2

and for windows users check the link below for a solution. Error installing mysql2: Failed to build gem native extension

I would recommend to use the normal command prompt.

Try to install these packages:

sudo apt-get install libmysqlclient-dev

sudo apt-get install bundler

After installing the bundler, run:

gem install mysql2

If the stack trace includes this error:

mkmf.rb can't find header files for ruby at /usr/lib/ruby/include/ruby.h

Look at what version of ruby you're using with:

ruby -v

Then install the correct version of ruby dev that goes with your version of ruby:

sudo apt-get install ruby2.0-dev
sudo apt-get install ruby2.2-dev
sudo apt-get install ruby2.3-dev

Then:

gem install mysql2

Sometimes you need to update your Ruby library, run this code: 

sudo gem update --system
