I’m doing a manual (initial) installation of ruby 1.8.7, rubygems  
1.3.7 and rails.  
I’m pretty new at this. This is a windows installation.  
I started by installing ruby-1.8.7, then downloaded rubygems-1.3.7 and  
ran ruby setup.rb in the extracted gems directory I had created. These  
seemed to go well.  
Then I did a  
gem install rubygems -updated  
and that completed successfully.  
The I did a  
gem install rails  
After installing 24 gems successfully there was a fatal error  
while installing ri documentation for activerecord-3.0.0  
an invalid argument  
-./\</cdesc-\<.yaml

I have not loaded any servers. Was I supposed to that before the rails  
install?

If is it only during the installation of the ri documentation, you  
shouldn’t  
worry about it.

if you do a ‘gem list’ you can see all the installed gems.

Hi,

why don’t you go for Ruby 1.9.2/Rails 3.0… I had different problems  
installing rails on windows until I found the following link:

> **[Running Rails 3 on Windows - Accidental Technologist](https://accidentaltechnologist.com/ruby-on-rails/running-rails-3-on-windows/)**

> Tweet Well, the long-awaited release of Ruby on Rails 3 is now out and all of the Mac and Linux junkies are busy gem-installing the latest version of the framework.? What about all the lonely Windows developers out there looking through their windows...
