的Rails的Ruby的gem版本問題

Question

我沒有與版本相關的內容進行不同項目的Ruby和現在當我要開始一個特定的項目，我有以下寶石錯誤：

/home/glory/.rbenv/versions/2.2.4/lib/ruby/2.2.0/rubygems/dependency.rb:315:in `to_specs': Could not find 'railties' (>= 0) among 14 total gem(s) (Gem::LoadError) 
Checked in 'GEM_PATH=/home/glory/.rvm/gems/ruby-2.2.4:/home/glory/.rvm/gems/ruby-2.2.4@global', execute `gem env` for more information 
    from /home/glory/.rbenv/versions/2.2.4/lib/ruby/2.2.0/rubygems/dependency.rb:324:in `to_spec' 
    from /home/glory/.rbenv/versions/2.2.4/lib/ruby/2.2.0/rubygems/core_ext/kernel_gem.rb:64:in `gem' 
    from /home/glory/.rbenv/versions/2.2.4/bin/rails:22:in `<main>' 

當我鍵入gem env我得到：

RubyGems Environment:

我該如何解決？

Answer 1

採取仔細看錯誤日誌的開頭：

/home/glory/.rbenv/versions/2.2.4/lib/ruby/2.2.0/rubygems/dependency.rb:315:in `to_specs': Could not find 'railties' (>= 0) among 14 total gem(s) (Gem::LoadError) 
Checked in 'GEM_PATH=/home/glory/.rvm/gems/ruby-2.2.4:/home/glory/.rvm/gems/ruby-2.2.4@global', execute `gem env` for more information 

和路徑信息：

- /home/glory/.rvm/gems/ruby-2.2.4/bin 
- /home/glory/.rvm/gems/ruby-2.2.4@global/bin 
- /home/glory/.rvm/rubies/ruby-2.2.4/bin 
- /home/glory/.rvm/bin 
- /usr/local/heroku/bin 
- /home/glory/.rbenv/plugins/ruby-build/bin 
- /home/glory/.rbenv/shims 
- /home/glory/.rbenv/bin 

您使用rbenv和RVM。

不要這樣做。

的rbenv documentation特別說：

Compatibility note: rbenv is incompatible with RVM. Please make sure to fully uninstall RVM and remove any references to it from your shell initialization files before installing rbenv.

我推薦使用

rm -rf ~/.rbenv 
rvm implode 

然後刪除其初始行你的〜/ .bashrc中，在〜/ .bash_profile和〜/刪除兩者。配置文件。

然後選擇一個或另一個，rbenv或RVM，並只重新安裝一個。這將迫使你重新安裝你想要使用的紅寶石以及相關的寶石，但它也會徹底修復這個爛攤子。

Answer 2

我認爲從你開始應用程序的地方會有ruby版本的問題。 切換到創建應用程序的其他ruby版本。 您可以使用下面的版本管理，切換到一個不同的版本

1. RVM
2. rbenv

使用方法：RVM使用{紅寶石版本}
