Error on starting application Bundler::GemNotFound

Question

I have just started a new app but am getting this error when I click the 'about your application's environment' link on the Welcome aboard page.

Error starting application Your Rack app raised an exception when Pow tried to run it.

Bundler::GemNotFound: Could not find activesupport-3.2.6 in any of the sources

My app is running:

Rails 3.2.6
Ruby 1.9.3p194
Rubygems 1.8.24
RVM 1.14.5
POW 0.4.0

I found similar questions where the problem was to do wit husing passenger, but I'm not using that.

When I run gem list I get:

* LOCAL GEMS *

Any help would be much appreciated, thanks.

Pow is probably trying to start your app with the "bundle exec" prefix. That means that your app will only see the gem which are in the Gemfile (and more precisely, only the gems which are in the groups of your current environment).

This is great because it enables you to have multiple apps using the same gem in different version : You might have an app using Rails 2 and another one using Rails 3, both are installed on your system but your first app says it depend on Rails 2 in its Gemfile and the other one specify Rails 3 as a dependency.

Long story short : You must declare each of your dependency in the Gemfile and run "bundle install" before accessing your app.

One more advice : Don't forget to specify the version of rake and even bundler you use, that might save your life when you upgrade those gems on your dev system but not on your prod server
