Rails Ruby Gem版本发行

Question

我对不同项目的Ruby进行了一些操作，现在当我想启动某个项目时，我有以下GEM错误：

/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>'

当我键入gem env时，我会得到：

RubyGems Environment:

我该如何解决？

Answer 1

仔细查看错误日志的开始：

/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

和路径信息中：

 - /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

您正在使用RBENV和RVM。

不要那样做。

RBENV文档专门说：

兼容性注意： rbenv与RVM不兼容。请确保在安装rbenv之前完全卸载RVM并从外壳初始化文件中删除对其的任何引用。

我建议使用

删除两者

rm -rf ~/.rbenv
rvm implode

然后从您的〜/.bashrc，〜/.bash_profile和〜/.profile文件中删除其初始化行。

然后选择一个或另一个，rbenv或rvm，然后仅重新安装那个。这将迫使您重新安装您要与相关宝石一起使用的任何红宝石，但它也将干净地修复烂摊子。

Answer 2

我认为Ruby版本从您启动应用程序的位置会出现问题。切换到应用程序创建的其他Ruby版本。您可以使用以下版本管理器切换到不同版本

1. rvm
2. rbenv

用法：rvm使用{ruby-version}
