You have to first set the path of DevKit in your environmental variable

Then run

gem install linecache19
gem install ruby-debug-base19
gem install ruby-debug-ide

through command prompt

May this work

"On Ubuntu, the native compilation step downloads the ruby 1.9.2 source and tries to unpack it into a directory that your current user probably does not have write access to." - Darren (Reference: http://isitruby19.com/linecache19)

In this case, try sudo bundle install.

If the problem is that it cannot resolve the vm_core.h file dependency, you can run the installs with specific versions and the path to the ruby source:

sudo -E gem install linecache19 -v=0.5.11 -- --with-ruby-include=path_to/ruby-1.9.1-p378/
sudo -E gem install ruby-debug-base19 -v=0.11.23 -- --with-ruby-include=path_to/ruby-1.9.1-p378/
sudo -E gem install ruby-debug-ide -v=0.4.9 -- --with-ruby-include=path_to/ruby-1.9.1-p378/

Reference: http://isitruby19.com/linecache19

Note, replace path_to/ruby-1.9.1-p378/, with the path to where you installed ruby.

To find out where you installed ruby, try running:

which ruby

From the RVM website:

If you have trouble installing ruby-debug19 try installing with the following command:

$ rvm reinstall 1.9.3 --patch debug --force-autoconf
$ gem install ruby-debug19 -- --with-ruby-include="${MY_RUBY_HOME/rubies/src}"
