ruby-debug install error: failed to build gem native extension

Question

I\'m running 1.9.2 with rails 3.

I\'m using rvm.

I did:

sudo gem install ruby-gem

and got:

Building native exte         


        

Answer 1

I had a similar issue (problem compiling native extensions) working in vpn behind the firewall and having http_proxy environment variable set. This case installer was unable to retrieve ruby tar file. I closed vpn and unset http_proxy variable and then successfully installed gem. I think --with-ruby-include is an alternative.

Answer 2

the ruby-debug gem is not compatible to Ruby 1.9.2. You need use the gem ruby-debug19

So change in your Gemfile to use this one

gem 'ruby-debug19'
