Pow not running my app in OS X 10.9 Mavericks

[nikolas]

Pow fails to boot my app when I call Bundler.require() in application.rb.

Pow log for my app:

The error seems to be the kind of opaque error you get when running a rails app in production mode, but when I print out Rails.env before the app fails to be, I am in development.

• Rails 3.2.14
• Bundler 1.3.5
• Ruby 2.0.0-p247
• Pow 0.4.1 / master
• OS X 10.9

I've tried swapping out the version of node pow uses in ~/Library/Application Support/Pow/Versions/0.4.1 for 0.10.22 with no luck.

Are you sure this is not a rails 3.2 + Ruby 2.0 error?

What does rails s tell you?

I fixed this problem I was having by reinstalling all my homebrew packages and making a new OS X user. Pow is working fine for me, now.

This still happens to me, after upgrading to rails 4 and running bundle install.

Started GET "/" for 127.0.0.1 at 2013-11-14 15:18:56 -0500
  ActiveRecord::SchemaMigration Load (1.0ms)  SELECT "schema_migrations".* FROM "schema_migrations"
Processing by PagesController#empty as HTML
Completed 500 Internal Server Error in 27ms

I can run . .powenv; bundle exec rails server to boot the server just fine.

Can you check what rails and ruby versions your app reports?
