安装rspec-rails和capybara gem时出错

Question

Brief Context:

My Gemfile looks like this:

source 'https://rubygems.org'

gem 'rails', '3.2.3'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

group :development do
    gem 'sqlite3', '1.3.5'
    gem 'rspec-rails', '2.9.0'
end

gem 'therubyracer'

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

  # See https://github.com/sstephenson/execjs#readme for more supported runtimes
  # gem 'therubyracer', :platform => :ruby

  gem 'uglifier', '1.2.3'
end

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

gem 'jquery-rails', '2.0.0'

# To use ActiveModel has_secure_password
# gem 'bcrypt-ruby', '~> 3.0.0'

# To use Jbuilder templates for JSON
# gem 'jbuilder'

# Use unicorn as the app server
# gem 'unicorn'

# Deploy with Capistrano
# gem 'capistrano'

# To use debugger
# gem 'ruby-debug19', :require => 'ruby-debug'

On running bundle install in my app folder, i am getting following error:

$ bundle install

Gem::RemoteFetcher::FetchError: SSL_connect SYSCALL returned=5 errno=0 state=SSLv3 read server certificate A (https://rubygems.cachefly.net/gems/diff-lcs-1.1.3.gem)
An error occured while installing diff-lcs (1.1.3), and Bundler cannot continue.
Make sure that `gem install diff-lcs -v '1.1.3'` succeeds before bundling.

However, if I comment out gem rspec-rails', '2.9.0' , its installing smoothly. I think the problem is with the way gem is installing. Kindly help with what to do? If you need more information, do tell me.

Answer 1

You can try to install the diff-lcs before bundling again

gem install diff-lcs -v '1.1.3
bundle install

Answer 2

Because of the nature of the SSL-specific error, you may want to consider switching to a non-secure connection to get the gems. As suggested in this other answer , check your Gemfile for a line like:

source 'https://rubygem.org'

and change it to the non-https version:

source 'http://rubygem.org'
