rails generate rspec:install returns 'Could not find addressable-2.2.8 in any of the sources'

问题

Currently I'm going through the Ruby on Rails Tutorial by Michael Hartl, chapter 3 (http://ruby.railstutorial.org/chapters/static-pages#top), and I'm receiving an error after running the following command:

rails generate rspec:install

This is the error I'm getting:

Could not find addressable-2.2.8 in any of the sources
Run 'bundle install' to install missing gems.

If I rerun 'bundle install', this is what I get for output:

Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.

I can see the path of 'addressable-2.2.8' if I type 'bundle show addressable'.

This is what my gemfile looks like:

source 'https://rubygems.org'

gem 'rails', '3.2.3'

group :development, :test do
gem 'sqlite3', '1.3.5'
gem 'rspec-rails', '2.10.0'
gem 'addressable', '2.2.8'
end

# Gems used only for assets and not required
# in production environments by default.
group :assets do
    gem 'sass-rails', '3.2.4'
gem 'coffee-rails', '3.2.2'
gem 'uglifier', '1.2.3'
end

gem 'jquery-rails', '2.0.0'

group :test do
gem 'capybara', '1.1.2'
end

group :production do
gem 'pg', '0.12.2'
end

It may help to know that I'm using rbenv, rails 3.2.3, and ruby 1.9.3p194.

EDIT: I have a feeling this may be related to the fact that I am using rbenv. I have a feeling that the rails project is looking in the wrong place for this particular dependency. Is there any way to force rails application to store dependencies/gems in the application itself and always load them there?

回答1:

I encountered this same exact issue. Here are the steps I followed to fix it.

1. Make sure source 'https://rubygems.org' is the first line in your Gemfile.
2. rm -rf .bundle
3. bundle install

回答2:

Try: bundle exec rails generate rspec:install
