Pow.cx Rails Resources Not Loading (IOErrror: Closed Stream)

Assets is the time for my Rails application, which runs locally through Pow. When I immediately visit the resource URL (for example, "/assets/home.css"), I get the following error:

{ "name":"IOError", "message":"closed stream", "stack":"/Users/XXX/Library/Application/ Support/Pow/Versions/0.4.0/node_modules/nack/lib/nack/server.rb:158:in `close' /Users/XXX/Library/Application Support/Pow/Versions/0.4.0/node_modules/nack/lib/nack/server.rb:158:in `ensure in handle' /Users/XXX/Library/Application Support/Pow/Versions/0.4.0/node_modules/nack/lib/nack/server.rb:158:in `handle' /Users/XXX/Library/Application Support/Pow/Versions/0.4.0/node_modules/nack/lib/nack/server.rb:99:in `rescue in block (2 levels) in start' /Users/XXX/Library/Application Support/Pow/Versions/0.4.0/node_modules/nack/lib/nack/server.rb:96:in `block (2 levels) in start' /Users/XXX/Library/Application Support/Pow/Versions/0.4.0/node_modules/nack/lib/nack/server.rb:86:in `each' /Users/XXX/Library/Application Support/Pow/Versions/0.4.0/node_modules/nack/lib/nack/server.rb:86:in `block in start' /Users/XXX/Library/Application Support/Pow/Versions/0.4.0/node_modules/nack/lib/nack/server.rb:66:in `loop' /Users/XXX/Library/Application Support/Pow/Versions/0.4.0/node_modules/nack/lib/nack/server.rb:66:in `start' /Users/XXX/Library/Application Support/Pow/Versions/0.4.0/node_modules/nack/lib/nack/server.rb:13:in `run' /Users/XXX/Library/Application Support/Pow/Versions/0.4.0/node_modules/nack/bin/nack_worker:4:in `<main>'" }

I am using Pow 0.4.0, Rack 1.4.5 and Rails 3.2.12.

I tried restarting the Pow site, restarting Pow, uninstalling and reinstalling Pow, and rebooting my machine.

It looks like you might need to update node.js. If you installed via Homebrew, you can use:

 brew update brew upgrade node npm update npm -g

This will update Homebrew and Node Package Manager.
