I need to get rid of some ruby gems to standardize my development environment before I begin creating my production environment on Slicehost. I ignored gems when I first started working with Rails and just followed the given setup instructions, but now it is time to dig in.
My Macbook Pro had a pre-existing Rails environment. Thus, I have tons of pre-existing ruby gems I want to get rid of first. However, when I do the following:
gem uninstall geokit
I get the following:
ERROR: While executing gem … (Gem::InstallError)
Unknown gem geokit >= 0
To get around this, I needed to get the install directory for this gem and then specify it when uninstalling:
gem list -d geokit
*** LOCAL GEMS ***
geokit (1.4.1)
Author: Andre Lewis
Rubyforge: http://rubyforge.org/projects/geokit
Installed at: /Users/JRagan/.gem/ruby/1.8
Geokit provides geocoding and distance calculation in an easy-to-use
API
I then specified the actual path to uninstall it:
gem uninstall –install-dir /Users/JRagan/.gem/ruby/1.8 geokit
Successfully uninstalled geokit-1.4.1
Happy day!
