Issue #7678 has been updated by Jacob Helwig.

Status changed from Unreviewed to Investigating

This is definitely coming from the version of Rails that is vendored with 
Dashboard (2.3.5).  We should upgrade the version of Rails used with Dashboard 
to get rid of this, and to get a few other niceties.  In the meantime, there 
seem to be a few workarounds listed [on 
StackOverflow](http://stackoverflow.com/questions/1814856/bypassing-rack-version-error-using-rails-2-3-5).

I've opened #7780 for the more general issue of what version of Rails we should 
upgrade Dashboard to.

Bug #7678: excessive versioned dependency on rack
https://projects.puppetlabs.com/issues/7678

Author: Guillaume Rousse
Status: Investigating
Priority: Normal

Branch: 
Affected URL: 
Affected Dashboard version: 


When running passenger through mod_rails, the versionned dependency on rack 
1.0.1 prevent the application to run if there is already a systemwide 
installation of this ruby module with a different version:

can't activate rack (~> 1.0.1, runtime) for [], already activated
rack-1.1.0 for ["passenger-2.2.9"]

Commenting this version dependency fix the issue, and let the application run 
apparently flawlessly. So, is there an actual reason to require a specific rack 
version ?
