Question

即使Nokogiri在Gemfile中列出，它也不会安装。帮助

[root@mongo p]# cat Gemfile
source 'http://rubygems.org'

gem 'rails', '3.2.12'
gem 'mysql2'
gem 'jquery-rails'


# ============================
# Gems

gem 'whois'
gem 'nokogiri'
gem 'bson_ext'
gem 'bson'
gem 'newrelic_rpm'
gem 'rpm_contrib'
gem 'savon'


# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails', '~> 3.2.3'
  gem 'coffee-rails', '~> 3.2.1'
  gem 'uglifier', '>= 1.0.3'
end


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

# Deploy with Capistrano
# gem 'capistrano'

# To use debugger (ruby-debug for Ruby 1.8.7+, ruby-debug19 for Ruby 1.9.2+)
# gem 'ruby-debug'
# gem 'ruby-debug19', :require => 'ruby-debug'

# Bundle the extra gems:
# gem 'bj'
# gem 'nokogiri'
# gem 'sqlite3-ruby', :require => 'sqlite3'
# gem 'aws-s3', :require => 'aws/s3'

# Bundle gems for the local environment. Make sure to
# put test-only gems in this group so their generators
# and rake tasks are available in development mode:
# group :development, :test do
#   gem 'webrat'
# end

Your bundle is complete! It was installed into ./vendor/bundle

请先删除 Gemfile.lock 文件以确保捆绑包重建所有依赖项，并首次安装所有gem，然后重新创建该文件：

$ bundle install

请确认 nokogiri gem已在 Gemfile.lock 中显示。然后确保 nokogiri gem正确安装类型：

$ bundle show nokogiri
/path/to/nokogiri/gem

我上面的命令显示错误其他人无法找到gem'nokogiri'，这意味着您的系统设置不正确。所以请不要使用root帐户，并使用简单的用户作为项目的持有者。并且将项目gem版本彼此分开使用rvm将gems安装到其gemsets中，因为它已经写成here。

Nokogiri即使在Gemfile中列出也没有安装为gem
