installing Radiant on DreamHost

Question

I am attempting to install Radiant on DreamHost, and when I get to the point where I do this:

radiant mysitename

It starts to install, then I get this error

/vendor/rails/activesupport/lib/active_support/dependencies.rb:55: uninitialized constant ActiveSupport::Dependencies::Mutex (NameError)

Now one thing I think it might be is that DreamHost has me using Rails 3, is that the case? If so, how can I run an older version? I am stumped - thanks.

Setup:

• ruby 1.8.7 (2008-08-11 patchlevel 72) [x86_64-linux]
• Rails 3.0.7
• Gem 1.8.2
• Radiant 0.9.1

No offense, but it works for me, even with the Rails which are installed on dreamhost. Make sure you don't have anything under vendor/rails in your application. And yes, Radiant requires 2.3.8 – Fotheringhay

Answer 1

This error is caused by the combination of RubyGems > 1.6.0 and Rails < 2.3.11 You could fix this by downgrading to rubygems version 1.5.3

gem update --system 1.5.3

The answer is the soon to be released Radiant 1.0

Essentially: a recent version of Rubygems introduced a change that changed some things Rails depended on. This was fixed in a point release of Rails (say 2.3.9), but Radiant 0.9 was based on a version of Rails before that.

There are ways to patch your Rails/Radiant apps to get it see my pull request on Github for this... which sometimes works (I've found issues with it over the last few days.

However I know that the Radiant core team wants to release a new version of Radiant today (May 18) or the next day. This will upgrade to the latest Rails 2.3 release, which solves the problem

This is fantastic news, I can wait :) – Azine

If you go to step 7 under Install RubyGems in this wiki it shows how to install an older version of Rails. Earlier in that section it also mentions checking for a different version number for Gem than the one you have listed.

I have installed the older version - I have even tried to uninstall all newer versions, but I still get 3.0.2...? – Azine

Hmmmm. So you followed the documented steps? How proficient are you with using a Unix (ie - Linux or OSX) based terminal? Just trying to get a grasp of your experience so I can help you troubleshoot. – Sellingplater

I have a good amount of experience with Linux - but I am no expert. I run Ubuntu on a box at home and went through 2 Computer Science degrees (MS/BS) which was basically all *nix machines. – Azine

@Azine Cool. Well since you have basic knowledge we can throw that out the window. Dreamhost also has a wiki. Did you try that? Sorry I can't be of more help. If I had a Dreamhost account I could go in there and try the install myself. It also sucks because it doesn't sound like this is something they support. – Sellingplater
