$ 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).

使用RVM 1.12.3,RubyGems 1.8.22,& Ruby 1.9.3。

我遇到了同样的问题。我认为问题在于宝石的缓存。尝试这个link中的步骤可能会解决问题。

在Windows上,

cd C:\Ruby193\lib\ruby\gems\1.9.1\gems
rm -rf ./*
cd ..\specifications
rm -rf /*

最后,

gem install rails

在Windows确定出现错误并重新启动时,此问题就开始发生了。
