Installing on CentOS

Ruby Apps Redcloth
1

Hi,

I’m trying to install RedCloth on CentOS. It came with ruby 1.8.5
pre-installed so I installed rubygems-1.2.0 since that seemed compatible
(later versions require ruby 1.8.6).

All looks good but when I try:

[root@dev4 rubygems-1.2.0]# gem install RedCloth
ERROR: could not find gem RedCloth locally or in a repository

Can anyone tell me what I’m missing? Do I need to configure some
repository
information?

Thanks,

Doug

P.S. Total Ruby/RubyGems novice - so I could be doing all manner of dumb
stuff…

Doug,
Sorry, I was away on vacation. I’m not sure why it’s not working. I
certainly have never tested it with Ruby or RubyGems that old. Even if
you
do get it to find it, it’s going to want to install a bunch of
dependencies
that aren’t necessary because older RubyGems didn’t have the concept of
development dependencies.

If it were me, I’d use RVM to install a recent version of Ruby and
RubyGems.
Otherwise, I imagine you’ll have problems with libraries other than
RedCloth
as well and it’s probably not worth figuring out. Good luck!

Hey Jason,

Thanks a lot for following up. I actually ended up discovering BitNami
(
http://bitnami.org) and installing a completely new Ruby stack to an EC2
instance and abandoning the whole CentOS physical server I was working
with. I’ve not tried RedCloth again yet but I suspect it’ll go much
easier
this time since I’m now running with current code.

One lesson I’ve learned is that Ruby is very version sensitive - so best
not
to swim upstream against that.

Thanks for the help,

Doug

I’ve also had to learn this over and over with different projects. It
sucks and is the main reason I’m hesitant to use Ruby.
