cannot load such file -- opal/browser

Try requiring just browser, also you probably don't want to use both browser and jquery.

[Roxas]

opal-jquery is just a leftover of a previous version, I already removed it.
Anyway, I'm still getting the same error even requiring browser in app/application.rb and in Rakefile.

[meh.]

It's require "browser" not require "opal/browser".

[Roxas]

As I just said, it still not working: cannot load such file -- browser

[meh.]

You're not adding the gems to the builder.

[Roxas]

require 'browser' is in both app/application.rb and Rakefile. Gemfile just installs the gem from GitHub. I think that should be enough to let opal-browser doing its work.

[meh.]

I don't use Opal::Environment directly, so I wouldn't know, @adambeynon anything comes to mind?

[Elia Schito]

I'd try adding a

require 'bundler'
Bundler.require

At the top of the rake file, otherwise bundler isn't able to put OB in your loadpath

[Adam Beynon]

If that still fails, inside the rake task print the opal load paths:

puts Opal.paths

That will say whether or not the browser gem is in opals load path for building.

[Roxas]

I've added bundler at the top of the rake file removing the require lines and all has worked as expected.
