Gemfile返回大量依赖

Question

我在Ruby on Rails中编写了一个项目，并试图部署它。这里是的Gemfile：

source 'http://rubygems.org' 
source 'http://gems.github.com' 

gem 'rails', '4.2.6' 

gem 'rake','0.8.7' 

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

#gem 'mysql2', '0.2.6' 
gem 'mysql2', '0.3.20' 

# GUID generator 
gem 'uuidtools', '2.1.2' 

# Paperclip: for image resizing 
gem 'paperclip', '2.4' 

# Delayed job 
gem 'delayed_job', '2.1.2' 

# Typus, admin interface 
gem 'typus', '3.0.2' 

# set attribute value to nil if blank 
gem "nilify_blanks", '1.0.0' 

# ssl gem 
gem "bartt-ssl_requirement", "~> 1.2.7", :require => 'ssl_requirement' 

# for social login 
gem 'omniauth', '0.2.0' 

# to detect user location 
gem 'geocoder', '1.1.0' 

# use to sanitize html 
gem 'sanitize', '2.0.1' 

# captcha for registration 
gem 'recaptcha', '0.3.1', :require => "recaptcha/rails" 
# base 32 
gem 'base32', '0.1.3' 

# amazon s3 
gem 'aws-s3', '0.6.2' 

#json 
gem 'json', '1.7.7' 

# pagination 
gem 'will_paginate', '3.0.pre2' 

# jammit for asset packaging 
gem 'jammit', '0.6.3' 

gem 'oniguruma' 

# 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' 

# Bundle the extra gems: 
# gem 'bj' 
# gem 'nokogiri', "1.4.4.1" 
# 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 

gem "fb_graph", "1.9.5" 

gem 'sitemap_generator', '2.1.8' 

gem 'fastercsv', "1.5.5" 

# to make it the same prior to 3.018 upgrade 

gem 'addressable', "2.2.4" 
gem 'arel', "6.0" 
gem 'attr_required', '0.0.3' 

gem 'cocaine', "0.2.0" 
gem 'daemons', "1.1.0" 

gem 'httpclient', '2.2.1' 
gem 'i18n', '0.5.0' 

gem 'mail', '2.5.4' 

gem 'mime-types', '1.16' 
gem 'multipart-post', '1.1.0' 
gem 'nokogiri', '1.4.4' 
gem 'oauth', '0.4.4' 
gem 'open4', '1.2.0' 
gem 'polyglot', '0.3.1' 
gem 'pyu-ruby-sasl', '0.0.3.2' 
gem 'rack', '1.6' 
gem 'rack-mount', '0.6.13' 
gem 'rack-oauth2', '0.9.2' 
gem 'rack-test', '0.5.6' 
gem 'rest-client', '1.6.1' 
gem 'ruby-openid', '2.1.8' 
gem 'treetop', '1.4.9' 
gem 'tzinfo', '1.1' 
gem 'xml-simple', '1.0.15' 

然后，我跑到bundle update要更新的，不是用rails 4.2.6兼容的宝石包。我得到这个错误：

Bundler could not find compatible versions for gem "activesupport":

    activesupport (>= 2.3) x86-mingw32 

因此，我增加gem 'activesupport', '4.2.6'创业板文件，并再次运行bundle update，但得到了同样的错误。我该如何解决它？

Answer 1

错误消息的第一行描述了情况：bundler无法找到满足Gemfile中其他gem冲突要求的活动支持版本。由于问题在于捆绑器无法找到合适版本的主动支持，因此手动指定版本不太可能有所帮助。

该消息的其余部分只是所有相关依赖项的列表，以帮助您找到冲突。从那里你可以看到你的Gemfile引脚delayed_job到版本2.1.2，这反过来又有一个要求，即主动支持〜> 3.0，这与使用rails 4.2.6的要求相冲突。

您需要删除或更新所需的延迟作业版本。从内存中，您需要4.0版或更高版本的延迟作业。这些版本也将延迟工作的核心从持久性后端的选择中分离出来，因此您还需要添加delayed_job_active_record宝石。延迟工作的升级说明有更多细节。
