Ruby on rails - Error during bundle install

Question

I\'ve been googling this error below, but I can\'t solve this error:

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

    /usr/bin/ruby2.1 ext         


        

Answer 1

Had similar error on fedora when trying to install compass for SASS development

gem install compass

failed with

Building native extensions. This could take a while... ERROR: Error installing compass: ERROR: Failed to build gem native extension.

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

Ran this

yum -y install gcc ruby-devel rubygems 

and then was able to run the install again successfully.

Try to install the ruby-dev library for your Ruby version which is 2.1

$ sudo apt-get install ruby2.1-dev
