Heroku在安装Gemfile依赖项时陷入困境

Question

When I try to deploy to heroku the gems never finished installing. I did a bundle update on my local machine to see if there was a problem. That did not help.

I suspect it might be libv8, but that should not be deployed because of the following in my config/application.rb file:

Bundler.require(*Rails.groups(:assets => %w(development test)))

Here is the log when I deploy my rails app to heroku:

$ git push heroku master

Answer 1

It was installing libv8. When I first started I needed that to get around some error. Now it seems I do not need it.
