Rails Ruby gem版本发布

Question

对于不同项目的Ruby版本，我做了一些事情，现在当我想要启动某个项目时，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>'

当我输入gem env时，我得到：

我该怎么解决呢？

Answer 1

仔细查看错误日志的开头：

/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

在路径信息中：

 - /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

你用的是rbenv和RVM。

别干那事。

rbenv文档特别指出：

兼容性注意： rbenv与不兼容。在安装rbenv之前，请确保完全卸载RVM并从您的shell初始化文件中删除对它的任何引用。

我建议删除这两种方法

rm -rf ~/.rbenv
rvm implode

然后从您的~/..bashrc、~/..bash_profile和~/.profile文件中删除它们的初始化行。

然后选择一个或另一个，rbenv或RVM，然后只重新安装其中一个。这将迫使您重新安装任何您想要使用的Rubies连同相关的宝石，但它也将干净地修复混乱。

我认为从你开始应用程序的地方，红宝石版本会有问题。切换到应用程序创建的不同的红宝石版本。可以使用下列版本管理器切换到其他版本

1. RVM
2. 里本夫

使用: rvm使用{ruby}
