How to check version of Ruby dev kit installed in my Windows?
ruby, ruby-on-rails, windows
Solution
On the 32 bit vs 64 bit part:
ruby -e "puts 1.size"
The 32 bit version would yield `4`, the 64 bit version `8`. (This is the size of a `FixNum` in bytes.)
Problem
Ruby dev kit is installed in my Windows 7. How can I check whether it's 32 bit or 64 bit and version number I'm not asking How to check ruby version which is `ruby -v`
