Cucumber installation problem

Hi to all,

I have managed to install many gems but cant seem to be able to install
Cucumer. It produces the error that system cannot find the path
specified. I am using Ruby 1.9.2 on windows 7. I tried installing
gherkin and the same error occurred. I managed to install other gems
such as rails, heroku etc from the same location using the same command
(gem install *****). Does anyone have any idea why this is happening?

Thanks,

Matias

Show us the exact command and error you are getting, copy it all from
the terminal and paste it here.

Ah, you are on Windows, sorry I don't know then. Someone else?

By the way, rails development is much easier on Ubuntu (or similar) or Mac.

I tried using ubuntu as its also installed on my computer but i couldn't
get the rails server running properly so decided to switch back since it
used to work in windows :smiley:

If you installed RubyInstaller's DevKit and still have issues, you
should check the troubleshooting page:

https://github.com/oneclick/rubyinstaller/wiki/Troubleshooting#wiki-gems_fails_comspec_autorun

Have you tried http://railsinstaller.org/?

I used that on windows, but I prefer rails on ubuntu… maybe in the future I’ll buy a mac :smiley:

Okay I managed to install cucumber but faced another problem when i
tried to install cucumber-rails. My cmd shows:

Try adding

gem 'ffi','1.0.9'

To your gemfile, 1.1.0 has issues.

Finally managed to install all the gems. I just added --platform Win32
to the end of the gem install cucumber-rails command and it worked fine.
Thanks to all who answered to my questions.
