如何将独角兽与rails 4.2.11相匹配

Question

红宝石程序在2.1.11版本之前运行良好，但是新的绑定程序需要红宝石版本>= 2.3。因此，我将ruby版本升级为2.4.5、bundler 1.17.3、rails版本为4.2.11、nokogiri为1.7.2、therubyracer为0.12.3、unicorn版本为5.0.1，Gemfile如下：

宝石'rails‘、'4.2.11’创业板'sqlite3‘、'1.3.13’宝石'sass-rails‘、'4.0.1’宝石'uglifier‘、'2.3.1’宝石‘咖啡-rails’、'4.0.1‘宝石'therubyracer’、'0.12.3'，平台:ruby宝石'jquery-rails‘、'3.0.4’创业板'turbolinks‘、'1.3.1’宝石'jbuilder‘、'1.5.2’。 组:医生做创业板'sdoc'，要求:假端创业板‘独角兽’，'5.0.1‘创业板’aws‘，'~> 3’创业板'haml-rails‘创业板'rbhive'，'0.5.1’创业板‘设计’'3.2.2‘创业板'net-ldap'，'0.5.1’创业板'devise_ldap_authenticatable‘创业板’将分页‘，'3.0.5’创业板‘延迟_job_active_record’，“4.1.0‘宝石’延迟_job‘，'4.1.0’创业板‘jquery 'jquery-turbolinks'，'2.0.2’gem 'jquery-ace-rails'，'1.0.1‘gem’jquery‘，'3.0.0’gem 'bootstrap-datepicker-rails'，'1.3.0.1‘ 创业板'rake'，'10.4.2‘宝石’mysql2 2‘，'0.3.16’宝石‘，'0.9.2’创业板‘activerecord-导入’，'0.10.0‘宝石’延迟_job_web‘，'1.4’创业板'hbase-stargate'，'1.6.1‘宝石’守护进程‘，'1.1.9’‘。

但是出现了错误：

我想知道独角兽是否与rails或其他原因不匹配？我该怎么做才能修好它？

Answer 1

试着降级独角兽的版本，一步一步地：https://rubygems.org/gems/unicorn/versions (检查这里的所有版本)

检查RoR 4.2.11发布日期，当时独角兽的版本是什么。
