Do I need to re-install gems after upgrading from Ruby 1.8.6 to 1.8.7 on
Unix?

Thanks Vamsi…in an attempt to understand things better, just curious
as to why this is needed? I already had all the latest versions of all
my gems installed…just updated ruby in /usr/lib/ruby. I’m not
questioning you’re reply, just trying to gain some knowledge.

Thanks again,
Brian

Brian,

/usr/local/lib/ruby/gems/1.6
/usr/local/lib/ruby/gems/1.7

These are the folders gems are installed(linux).So all your previous
installation gems will be in the 1.6 folder.What you can do it you can
simlink 1.7 to 1.6 and it shud work fine.But some cases it might cause
issues.so I have suggested to reinstall all the gems.

Thanks,
Kilari.

This is actually not the case!

If you are using ruby 1.8.6 OR 1.8.7 your gems will be in gems/1.8
for example on my Mac: /Library/Ruby/Gems/1.8
on my Linux: /usr/lib64/ruby/gems/1.8

You will need to reinstall if you upgrade to ruby 1.9
You will also need to reinstall if you upgrade to REE (ruby enterprise
edition) since it uses a separate directory too.
on the same linux ree installation uses /usr/lib64/rubyee/gems/1.8

Note that those installations can coexist on the same machine. they
use binaries like ruby18, rubyee, ruby19, gem18, gemee, gem19
with ruby and gem usually being a symlink to one of the above.

Thanks all…I was able to move on w/out re-installing the gems.
