ruby - Error in Installing Rails Using DevKit -

im trying install rails using devkit on windows 7

i have installed railsinstaller

i added path ruby2.1.0 in config.yml:

# configuration file contains absolute path locations of # installed rubies enhanced work devkit. config # file generated 'ruby dk.rb init' step , may modified # before running 'ruby dk.rb install' step. include installed # rubies not automagically discovered, add line below # triple hyphens absolute path ruby root directory. # # example: # # --- # - c:/ruby19trunk # - c:/ruby192dev # --- - c:/railsinstaller/ruby2.1.0 

when ever try run

ruby dk.rb install 

it gives me following :

[info] skipping existing gem override 'c:/railsinstaller/ruby2.1.0'
[warn] skipping existing devkit helper library 'c:/railsinstaller/ruby2.1.0'

when tried use force option:

ruby dk.rb install --force 

i :

[warn] updating (with backup) existing gem override 'c:/railsinstaller/ruby2 .1.0' [warn] updating (with backup) devkit helper library 'c:/railsinstaller/ruby2 .1.0'

i've answered other stack overflow questions similarly. here:

warnings being treated errors in rails

but honest suggestion nip rails development in bud, , start developing on osx or linux. grateful did. ruby naturally linuxy in nature, , getting out of windows environment save lot of heart , head ache.

i recommend using vagrant virtual machine on windows ruby development. vagrant runs linux ubuntu , allows sync folders between local machine , virtual machine. documentation , instructions here:

http://docs.vagrantup.com/v2/getting-started/index.html

of course, if have access mac, osx comes preinstalled ruby, should take minutes rails environment ready go. if don't, vagrant great virtual machine run with.
