How to install a gem via user account?

Posted March 25, 2015
Ruby on Rails

I am logged in as user. I gave all root privileges to user. Now I am doing bundle install. It is breaking by saying "Make sure that gem install nokogiri before bundling. Now when I try to install by gem install nokogiri , it says permission denied. When I try it with sudo gem install nokogiri, then it says “sudo: gem: command not found”. How can I install this gem?

If you have Ruby installed I am not sure why sudo would say that the command was not found. I would recommend checking that Ruby is installed:

sudo apt-get update;
sudo apt-get install ruby

Then try running the gem install using the full path:

sudo /usr/bin/gem install nokogiri

Some gems may require additional libraries in order to build and if you encounter errors you may want to try installing ruby-dev and build-essential to start with.
