Will running sudo apt-get install ruby1.9.1-dev disturb rvm?

Question

I have already installed rvm and few versions of rubies. Here is the list

$ rvm list
rvm rubies

   ruby-1.9.1-p431-dev [ i686 ]
=> ruby-1.9.3-p484 [ i686 ]
 * ruby-2.0.0-p247 [ i686 ]
   ruby-2.0.0-p353 [ i686 ]


# => - current
# =* - current && default
#  * - default

I tried sudo gem install jekyll in all versions but getting the same error again and again

sudo gem instal jekyll
Building native extensions.  This could take a while...
ERROR:  Error installing jekyll:

How to proceed with the Jekyll installation.

When reading about Troubleshooting Installation Problem they have mentioned to Install ruby1.9.1-dev package through

sudo apt-get install ruby1.9.1-dev

Will it solve my issue without disturbing the rvm? Please guide me.

Answer 1

It seems either the build of ruby-1.9.1 isn't completed, or some of build-in modules for the ruby are absent, for example mkmf. So you have to add-in the module into the ruby-1.9.1 installation if any, in order to be able to build native gems with the ruby.

When reading about Troubleshooting Installation Problem they have mentioned to Install ruby1.9.1-dev package through

sudo apt-get install ruby1.9.1-dev

Of course try to install, and then do in irb of the ruby-1.9.1:

require 'mkmf'
