Installing termios gem on Mac OS X
Posted: February 3rd, 2007 Tags: Mac OS X, Ruby on Rails, Web developmentWhen installing Capistrano, you should install the termios gem so that your password isn’t echoed when you type it.
Easier said than done
Here’s the error I got:
$sudo gem install termios

It was looking for header files in /usr/lib/ruby/1.8/powerpc-darwin8.0, but they weren’t there; they were in /usr/lib/ruby/1.8/universal-darwin8.0.
The Solution
The solution was simple enough: create symlinks to the header files:
$sudo ln -s ../universal-darwin8.0/*.h ./ $sudo gem install termios
