Question

Can anyone help me out, ive got Ruby 1.9.1 installed and Ruby Gems 1.8, here is the error message:

~$ sudo gem install rhc
Building native extensions.  This could take a while...
ERROR:  Error installing rhc:
ERROR: Failed to build gem native extension.

Answer 1

Based on Michael Frederick comment, for my Linux Mint 12 Lisa 32 bits, i have the same error, the final solution for install Ruby apps to manage Openshift cloud its the follow:

sudo apt-get install ruby1.8
sudo apt-get install gem
sudo apt-get install rubygems
sudo gem install json_pure
sudo gem install rake
sudo gem install rhc

Actually you might want to try installing the Ruby Version Manager (RVM) package instead of the standard ruby packages which tie you to a specific version of ruby. You should look at the bottom of this page where I list some directions on how to install the rvm and rhc on ubuntu.
