安裝rspec-rails和capybara gem時出錯

Question

簡要背景：

我的Gemfile看起來像這樣：

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'

在我的應用文件夾中運行捆綁安裝時，出現以下錯誤：

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.

但是，如果我注釋掉gem rspec-rails''2.9.0' ，則安裝順利。 我認為問題出在gem的安裝方式上。 請幫忙怎么辦？ 如果您需要更多信息，請告訴我。

Answer 1

您可以嘗試在再次捆綁之前安裝diff-lcs

gem install diff-lcs -v '1.1.3
bundle install

Answer 2

由於特定於SSL的錯誤的性質，您可能需要考慮切換到非安全連接以獲取gem。 就像在其他答案中所建議的那樣，檢查您的Gemfile是否有類似以下內容的行：

source 'https://rubygem.org'

並將其更改為非https版本：

source 'http://rubygem.org'
