Bundler找不到宝石“机架”的兼容版本： [英] Bundler could not find compatible versions for gem "rack":

问题描述

我是Ruby新手，但实际上如果我不想安装Redmine，我不需要它。我正在按照 http://www.redmine.org/projects/redmine/wiki / HowTo_install_Redmine_on_CentOS_Detailed

I am new to Ruby but actually I don't need it if I don't want to install Redmine. I am following the instructions at http://www.redmine.org/projects/redmine/wiki/HowTo_install_Redmine_on_CentOS_Detailed

我已经安装了ruby 1.9使用

I have installed ruby 1.9 using

rvm install 1.9.3

和红宝石使用...

sudo yum install rubygems

然后来创建Gemfile并注册这些宝石的部分

Then coming to the part of creating the Gemfile and register these gems in it

# 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" 

和我的文件看起来像...

and my file looks like...

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

当我运行

When I run

bundle install

它给了我...

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)

我不知道该怎么做。

I don't know what to do.

推荐答案

（1.4.5），其中之前的版本已锁定在机架（1.1.0）上，以便快速修复

You updated the rails version which required rack (1.4.5), where previous version was locked on rack (1.1.0), for a quick fix

删除 gemfile.lock 并运行捆绑安装再次

希望它能解决您的问题...

hope it will resolve your problem...
