Odd script/server error

rubyonrails-talk
1

hi,

I am fairly new to rails, I started learning it about 6 months ago, but stopped when a big project came up. That was on a Windows machine. Since then, I have purchased a mac power book. I am ready to again. I installed rails following the much used HiveLogic tute and everything seemed to work.

In any event I created a small test app: controller, view, etc in a directory in ~/Documents/rails/app/demo.

When I created the app, I made a simple controller and view and started teh server (script/server) and everything worked fine. I restarted my computer and went to start the server (I am in the 'demo') directory I get this error:

Rails requires RubyGems >= 0.9.4. Please install RubyGems and try again: http://rubygems.rubyforge.org

This doesn't seem to make sense because when I update something using he gems command it works, furthermore, when I test the gems version I get this:

$ gem --version1.0.1

I am running Rails 2.02

and Ruby: 1.8.2 (2004-12-25) [universal-darwin8.0]

on OS X 10.4

Any ideas?

To get the gem version do:

gem env

  1. sudo gem update --system. This will upgrade the Ruby gems to 1.0.1

  2. sudo gem install rails --source http://gems.rubyonrails.org Note that gem install -y is the default, so you don’t have to provide it.

Thanks for the reply, but that is not the issue, I already have the most recent version of both gems and rails, I feel as though the error is wrong, and that the issue it is giving is not correct. that is to say, I have done something wrong, but not having gems installed is not the issue.

That's the antique version of ruby that Tiger shipped with isn't it?
If you followed the hivelogic tutorial you;ll have a new version
installed, is your $PATH currently set properly so that the new
version of ruby (which will have a separate set of gems etc..) is
invoked ?

Hi,

I get the same error on my ubuntu linux installation when I create a new rails-project.

tn@spike:$ ruby -v ruby 1.8.6 (2007-03-13 patchlevel 0) [i686-linux] tn@spike:$ gem -v 1.0.1 tn@spike:$ ruby script/console Rails requires RubyGems >= 0.9.4 (you have 0.9.0). Please `gem update --system` and try again.

It works fine for old projects though? The gem version control seems a bit buggy. Any ideas what to do? I've tried to reinstall rubygems, but it don't help.

Best regards, Tobias
