如何修复"未知的ruby解释器版本(不知道如何处理)"

Question

我在运行优胜美地的Mac上在rails环境中设置了ruby和ruby,我正在尝试通过教程.当我在bash终端中执行以下操作时,我立即停止这样做:

$ rvm use ruby-2.2.1@ learn-rails --create
Unknown ruby interpreter version (do not know how to handle): learn-rails.

我相信一切都设置正确.这是我在执行以下操作时得到的结果:

$ rvm list

rvm rubies

   ruby-2.2.0 [ x86_64 ]
=* ruby-2.2.1 [ x86_64 ]

# => - current
# =* - current && default
#  * - default

和:

$ ruby -v
ruby 2.2.1p85 (2015-02-26 revision 49769) [x86_64-darwin14]

$ rails -v
Rails 4.2.1

$ rvm -v
rvm 1.26.10 (latest) by Wayne E. Seguin <wayneeseguin@gmail.com>, Michal Papis <mpapis@gmail.com> [https://rvm.io/]

$ echo $PATH
/Users/jeff/.rvm/gems/ruby-2.2.1/bin:/Users/jeff/.rvm/gems/ruby-2.2.1@global/bin:/Users/jeff/.rvm/rubies/ruby-2.2.1/bin:/usr/local/heroku/bin:/Users/jeff/.rbenv/shims:/Users/jeff/.rbenv/shims:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Users/jeff/.rvm/bin

感谢您的帮助!

@角色和角色之间应该没有空格learn-rails.额外的空间导致RVM误learn-rails用作Ruby的一个版本.该行应为:

rvm use ruby-2.2.1@learn-rails --create
