Install Old Versions of Ruby Gems
I am setting up a new machine that has some old software requirements for my project this week. A quick tip if you need gems to be installed at an older version (if they are still available).
Use the -v version flag to specify which version you want.
sudo gem install capistrano -v 1.4.1
If you’ve got the newer versions of the capistrano gem, no need to fret. You can specify the version you want to use on the command line like this:
cap _1.4.1_ deploy
You can alias that to something else in your bash profile by adding something like this:
alias cap1='cap _1.4.1_'
