Bundler找不到gem“rack”的兼容版本:

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

和ruby gems使用……

sudo yum install rubygems

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

然后来创建Gemfile并在其中注册这些gem。

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)

I don't know what to do.

我不知道该怎么办。

1 个解决方案

#1

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

您更新了rails版本，它需要机架(1.4.5)，以前的版本锁在机架上(1.1.0)，以便快速修复

remove the gemfile.lock and run bundle install again

删除gemfile。再次安装并运行bundle。

hope it will resolve your problem...
