ERROR: Failed to build gem native extension - Error installing mysql2

error while running bundle install

Installing mysql2 (0.3.11) with native extensions 
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.
...
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.

Solution

  • 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.
