在gem --version之后运行时,获取"不是Gem :: Specification(NilClass代替)"

Question

$ gem --version

[/home/rohit/.rvm/gems/ruby-1.9.3-p125@qnrDashboard/specifications/net-ssh-2.5.2.gemspec] isn't a Gem::Specification (NilClass instead).
[/home/rohit/.rvm/gems/ruby-1.9.3-p125@qnrDashboard/specifications/net-sftp-2.0.5.gemspec] isn't a Gem::Specification (NilClass instead).
[/home/rohit/.rvm/gems/ruby-1.9.3-p125@qnrDashboard/specifications/net-ssh-gateway-1.1.0.gemspec] isn't a Gem::Specification (NilClass instead).
[/home/rohit/.rvm/gems/ruby-1.9.3-p125@qnrDashboard/specifications/net-scp-1.0.4.gemspec] isn't a Gem::Specification (NilClass instead).

使用RVM 1.12.3,RubyGems 1.8.22和Ruby 1.9.3.

为什么我收到此错误？
