I wasn’t sure if I had ever updated Rails on my MBP, and so, as I begin developing my first real project, I thought it was time. A regular gem update didn’t work. I had to use sudo:
sudo gem update rails --include-dependencies The same applied for gem cleanup, which deleted the following items — after asking me for confirmation:
Successfully uninstalled rails-1.2.6
Successfully uninstalled rake-0.7.3
Successfully uninstalled actionwebservice-1.2.3
Successfully uninstalled activerecord-1.15.3
Successfully uninstalled actionmailer-1.3.3
Successfully uninstalled actionpack-1.13.3
Successfully uninstalled activesupport-1.4.2 I now have to do the same on the iMac.
