我正在尝试创建一个新的rails项目（就像rails new bloccit）。但我得到一个奇怪的错误，无法继续。
这是我得到的错误：
/Users/marcvanderpeet/.rvm/gems/ruby-2.0.0-p598/bin/rails:23:in `load': cannot load such file -- /Users/marcvanderpeet/.rvm/gems/ruby-2.0.0-p598/gems/rails-4.2.0/bin/rails (LoadError)
from /Users/marcvanderpeet/.rvm/gems/ruby-2.0.0-p598/bin/rails:23:in `<main>'
from /Users/marcvanderpeet/.rvm/gems/ruby-2.0.0-p598/bin/ruby_executable_hooks:15:in `eval'
from /Users/marcvanderpeet/.rvm/gems/ruby-2.0.0-p598/bin/ruby_executable_hooks:15:in `<main>'
有关导致此问题的原因的任何线索？
