Bundler找不到與寶石“ rack”兼容的版本：

Question

我是Ruby的新手，但實際上，如果我不想安裝Redmine，就不需要它。 我正在按照http://www.redmine.org/projects/redmine/wiki/HowTo_install_Redmine_on_CentOS_Detailed上的說明進行操作

我已經使用安裝了Ruby 1.9

rvm install 1.9.3

和紅寶石寶石使用...

sudo yum install rubygems

然后進入創建Gemfile的部分並在其中注冊這些gems

# file: /var/www/redmine/Gemfile
source "http://rubygems.org" 
gem "rake", "0.8.3" 
gem "rack", "1.1.0" 
gem "i18n", "0.4.2" 
gem "rubytree", "0.5.2", :require => "tree" 
gem "RedCloth", "~>4.2.3", :require => "redcloth" # for CodeRay
gem "mysql" 
gem "coderay", "~>0.9.7" 

我的文件看起來像...

source 'https://rubygems.org'
gem "rake", "0.8.3"
gem "rack", "1.1.0"
gem "i18n", "0.4.2"
gem "rubytree", "0.5.2", :require => "tree"
gem "RedCloth", "~>4.2.3", :require => "redcloth" # for CodeRay
gem "mysql"


gem "rails", "3.2.15"
gem "jquery-rails", "~> 2.0.2"
gem "coderay", "~> 1.1.0"
gem "fastercsv", "~> 1.5.0", :platforms => [:mri_18, :mingw_18, :jruby]
gem "builder", "3.0.0"

# Optional gem for LDAP authentication

當我跑步

bundle install

它給我...

Resolving dependencies...
Bundler could not find compatible versions for gem "rack":
  In Gemfile:
    rails (= 3.2.15) ruby depends on
      rack (~> 1.4.5) ruby

    rack (1.1.0)

我不知道該怎么辦。

Answer 1

您更新了需要機架（1.4.5）的rails版本，以前的版本已鎖定在機架（1.1.0）上，以便快速修復

刪除gemfile.lock並再次運行捆綁安裝

希望它能解決您的問題...
