Question

I have Windows Server 2008 R2 with MySQL and Subversion installed separately. Just to mention that it is also having IIS.

We are currently installing Redmine on the same server, and following instructions from this page:

http://www.richardnichols.net/2009/09/1-minute-guide-installing-redmine-on-windows/

While installing this we’ve struck at step no. 8 with error on Rake aborted!

Here is the complete error text:

What could be causing this, and how to fix this. I’m not an expert at ROR.

Thanks daemonsly, As per your update, I have downgraded Ruby Gems version. Error has been changed, but still not able to proceed further. Here is the exact error I’m getting:

C:\Ruby187\Apps\Redmine>gem -v
1.6.2

C:\Ruby187\Apps\Redmine>rake db:migrate
rake aborted!
RubyGem version error: rack(1.4.1 not ~> 1.1.0)

Answer 1

You might need to downgrade your Ruby Gems version.

Try gem update --system 1.6.2

Update

Sorry, I have little experience with RoR on Windows. But basically, you should be having problems due to Redmine using older version of gems.

You should first try running bundle install to see if you already have all the specified gems. If rake still won’t run, try exec rake db:migrate.

Finally, brute force if necessary.
gem uninstall rack then gem install rack -v 1.1.0

The premise of these actions is try to get the right gem versions.
