Redmine上缺少配置/环境

Question

I have upgrade my rails version to 3.0 and I got the following error message

no such file to load -- path_to_application/config/environment

Please help me to solve this problem.

Thanks in advance.

Answer 1

It looks like Rails 3 support is at best beta: http://www.redmine.org/issues/4796

It looks like Rails 3.0 is not supported:

Redmine will never run with 3.0 due to the lack of engine support.

From the above linked issue, the developers seem to be targeting Rails 3.1

Answer 2

I guess that the Rails 3 you have installed override Redmine's Rails 2.3.

One simple way to fix that is to add Bundler to your Redmine installation, which will put it into an isolated set of gems.

See Using Bundler with Rails 2.3 .
