    @SaadMasood got it Gem files will remain installed in /Users/SMD/.rvm/gems/ruby-2.0.0-p247/gems/atomic-1.1.13 for inspection. so it is for gem name as atomic and you required java jdk 8 github.com/headius/ruby-atomic last line As of 1.1.0, JDK8 is required to build the atomic gem, since it attempts to use the new atomic Commented Aug 27, 2013 at 11:06

Is that a gem to install or an apt-get command? What commands did you use?

Here's an answer that helped me: Ruby on Rails - unable to convert "\x89" from ASCII-8BIT to UTF-8 for xxx/xxxx/xxxx

You need to update / install a version of the rdoc gem that supports the conversion. Then these errors won't appear during generation of the documentation when you install rails or when you regenerate the documentation.

gem install rdoc

Then to regenerate the documentation

gem rdoc --all --overwrite

then do gem update and gem install rails

Also, make sure that rvm is a function type rvm | head -1

got it Look into your error:--

`Gem files will remain installed in /Users/SMD/.rvm/gems/ruby-2.0.0-p247/gems/atomic-1.1.13

for inspection. so it is for gem name asatomicand you requiredjava jdk 8github.com/headius/ruby-atomic last line stated as of1.1.0,JDK8 is required to build the atomic gem, since it attempts to use the new atomic`

Please install JDK 8
