Updating Ruby on Windows & Installed Gems

Ruby
1

Hello,

I’d like to update the version of Ruby I have on this Windows box
(installed using the One Click installer), which is currently at 1.8.6
(2007-03-13 patchlevel 0). I’ll use either the p111 version of the One
Click installer, or the patched version offered by Mike Hodgson at
http://www.mikehodgson.com/ruby186-27-mkh.exe

However, the first step to installing the update is to uninstall the
current version. Will that nuke all of the installed gems I currently
have? How can I preserve my gems (currently 80!)

Thanks!

John

Inside your installation of One-Click Installer, there is a gems
folder:

Example for ruby installed in C:/Ruby

C:/Ruby/lib/ruby/gems/1.8

  1. Use Explorer to browse to that folder and copy it’s contents into a
    safe place.

  2. Uninstall current One-Click Installer

  3. Installer newer version (you pick one, I suggest stick to 1.8.6
    with patches).

  4. Copy back your contents in the same folder.

  5. Done.

It should work, verify it for your self :smiley:

HTH,

HTH,

I’ll give it a try. One thing I realized/noticed, the individual
commands for some of the gems (‘rails’, ‘capify’, ‘autotest’, etc’) live
in c:\ruby\bin. I’ll make a backup of that too! (and keep a list of my
installed gems… just in case!)

Thanks

Just for future reference. I did save a copy of the c:\ruby\bin and the
C:/Ruby/lib/ruby/gems/1.8 directories. Good thing I saved the bin
directory! After uninstalling, the whole c:\ruby directory was gone.
After reinstalling, I hand copied the missing files from my back up of
c:\ruby\bin to the newly created one, and just replaces the whole
C:/Ruby/lib/ruby/gems/1.8 with the backup. Everything seems to be
working fine!

Thanks!
