It's rdoc gem problem i'll find this issue on github. Update rdoc gem and reinstall rails.
i figured it out after following various articles.
Follow are the Steps.
$rvm get head$rvm --force 2.0.0$gem update$gem install railswent through smoothly.
Following is the output:
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.
Then to regenerate the documentation
then do
gem updateandgem install railsAlso, make sure that rvm is a function
type rvm | head -1
