PATH is actually very simple. rvm/bin We can see that this is just a list of directories, separated by colons. As you can see, on this machine I’m using rvm so I have a lot of rvm specific directories in mine. If you were running rbenv you might see something like this: 1 2 /usr/local/rbenv/shims:/usr/local/rbenv/bin:/usr/local/sbin:/usr/local/bin:/us\ r/sbin:/usr/bin:/sbin:/bin:/usr/bin/X11:/usr/games When you enter a command, such as “rake” or “irb,” in the console, the system searches through each of the directories in $PATH, in the order they are displayed, for an executable file with that name.

If a major vulnerability is discovered within Rails, it’s essential you have a plan in place to upgrade within days if not hours of this being released.

We’ll be installing both rbenv and ruby versions using a chef recipe below but for more on using rbenv in your development environment, see the official documentation which is excellent. com/sstephenson/rbenv The rbenv Cookbook We’ll be using fnichols excellent chef-rbenv cookbook which will be in your cookbooks/chef-rbenv folder. 0 - Installing Ruby 55 The rbenv::system performs a system wide install of rbenv, this means that it’s installed to /usr/local/rbenv rather than ∼/rbenv. This is generally my preference as it reduces issues caused by, for example, cron jobs running as root.
