的Ruby版本和项目不匹配

当我运行，bundle我看到以下内容：的Ruby版本和项目不匹配

Your Ruby version is 2.5.0, but your Gemfile specified 
2.4.0.pre.dev

我的Gemfile看起来像：

source 'https://rubygems.org' 
ruby '2.4.0-dev' 
gem 'sinatra', :github => 'sinatra/sinatra'

这是我gem env：

$ gem env 
RubyGems Environment:

    - /usr/local/bin 
    - /usr/bin 
    - /bin 
    - /usr/sbin 
    - /sbin

当我输入rbenv verions这就是我所看到的：

system 
    2.0.0-p247 
    2.3.1 
* 2.4.0-dev (set by /Users/johndoe/code/projects/blog-server/.ruby-version)

随着Rbenv我指定了我想要的红宝石版本，我在我的项目的Gemfile中匹配这个。然而，每当我运行bundle或bundle exec gem uninstall sinatra我看到上述有关我的ruby版本和我的gemfile ruby版本不匹配的错误消息。我也看到我的Ruby版本是2.5.0，我不知道如何设置。有人可以帮我解决这个错误吗？

Your Ruby version is 2.5.0, but your Gemfile specified 
2.4.0.pre.dev

在我的bash的个人资料，我有：

export PATH=$HOME/.rbenv/bin:$PATH 
.... 
eval "$(rbenv init -)"

总之，我只想运行我的红宝石过程为我的博客项目使用Ruby版本2.4.0-dev外壳，和我很努力请参阅了解阻止我的方式以及如何解决问题。

更新：

我还注意到一些奇怪的东西。我的捆绑版本继续指向红宝石2.5.0p-1。

在[本期]（https://github.com/bundler/bundler/issues/4260）中有几个想法在捆绑销售商回购协议中，你有没有经历过那个然而？特别值得注意的是，最后一篇文章提到他需要运行'rbenv rehash'（注意，因为我看到你在使用rbenv） –

@SimpleLime我熟悉那个线程，没有任何东西适用于我。每次我卸载bundler并重新安装时，其Ruby版本仍然是'Ruby 2.5.0p-1'。 – robertjewell
