Could not find RubyGem rack (~) 1.0.1) what should I do ? please help me

Answer 1

You need to write this in your command prompt:

gem install rack

Answer 2

It's telling you that you need a specific version of the Gem called "rack". You can install it by doing:

gem install rack -v=1.0.1

This will only install it to your local gem directory. If you want to install it globally (which is recommended for production environments), simply do:

sudo gem install rack -v=1.0.1

This will prompt you for the administrator password as usual.
