is there a way tu run redmine in Rails 3 ?
i've to setup a new server and will use this as the rails3 development-environment. is there a way to run redmine on this macine - i've been searching for redmine+rails3 howto but did not find something …
Nope, Redmine needs 2.3. Install rvm and use its gemset feature to use rails 2.3 just for Redmine.
but how can i run rails3 in ruby 1.9 while rails2 will use ruby1.8 - rvm has (as far as i know) only the ability to seperate the rails-environment but there is only one ruby-interpreter at the system …
Nope, the primary use of rvm is to use different versions and types of ruby interpreters, the gemset feature is a bonus.
