Undefined method `name' for "SystemTimer":String

I am having a problem getting an old Ruby on Rails 2 app that hasn't worked in a year to work.

I'm trying to run rake test:functionals in the root of my project directory, but am getting undefined method 'name' for "SystemTimer":String.

I've pasted everything that I believe relevant to the problem here: http://pastebin.com/NgBvystZ

Also, when I run rake itself, I get开发者_开发问答 Errors running test:units! Not sure how to debug that.

I have copied and pasted everything that I think would be useful to understanding this problem. Your time is greatly appreciated. Thank you.

This is an incompatibility between versions of RubyGems greater than 1.3.7 and versions of Rails less than 2.3.12. There are a few ways to solve this.

1. Use Bundler

   Bundler is easy to install, fixes this problem, and has a number of other advantages as well. I highly recommend it.

2. Upgrade to Rails 2.3.12 or higher

   Rails 2.3.12 fixed compatibility issues with RubyGems 1.8.5 (see release report).

3. Downgrade to RubyGems 1.3.7

   I would not recommended this unless you have no other choice. Use this command: gem update --system 1.3.7. Also, version 1.7.2 has partial compatibility (it will run, but freezing gems will fail and there are likely other issues).

I chanced upon this thread, because I got the following error when migrating some Radiant 0.9.1 installations to a new server:

undefined method `name' for "RedCloth":String

(3) The compromising solution: I haven't tested this personally, but I hear that rails 2.3 with bundler is compatible with the latest rubygems. If you're interested in this solution, see http://gembundler.com/rails23.html for getting bundler to work under rails 2.3.

For me solution 3 was the only option, since we had other apps needing the latest rubygems on the system. Just install bundler and follow thes steps on this page: http://gembundler.com/rails23.html

And put this in a file called "Gemfile" in the app root:

source :gemcutter
gem "radiant", "0.9.1"
gem "sanitize"
gem "fastercsv"
gem "rmagick"
gem "rack", "~> 1.1.0"
gem "rake", ">= 0.8.3"
gem "RedCloth", ">= 4.0.0"
gem "will_paginate", "~> 2.3.11"
gem "mysql"

This is just my example. Start with only the first 2 lines, run bundle update and reload the page to see what else you might be missing.

Thank you Ben!
