I think you may find it difficult to get help when running Rails on
Windows. I strongly suggest using a Linux distribution such as
Ubuntu, or a Mac as do most developers. You can run Ubuntu in a
virtual machine on top of windows (using VirtualBox or VMWare) or you
can dual boot your machine to run whichever is appropriate. Once you
start using Linux you will wonder why you stuck with Windows. It is
great to feel in control of the PC again.

Unfortunately I need to start Web Server in Windows 7. Please let me know if you have any solution for Windows 7.

No, I have no solution for that, whether you will find a solution I do
not know. Very few Rails servers run on Windows. I suggest that you
tell whoever is instructing you that you must do this to think again.

Exactly as the error says, try the following:
Please update your PATH to include build tools or download the DevKit

from ‘http://rubyinstaller.org/downloads’ and follow the instructions

at ‘http://github.com/oneclick/rubyinstaller/wiki/Development-Kit

Well if rails and gem are working I wonder:

Have you installed the dev kit?

Looks like the Json gem is failing because the dev kit isnt installed and it needs the build tools inside it

If you have installed the dev kit make sure you follow its instructions. It probably the path issue your error mentions.

Ive used this setup before though so I know its doable

Hi Rohan,

To add to Clayton’s message re DevKit. You may use the following instructions.

Download DevKit file from
http://rubyinstaller.org/downloads (DevKit-tdm-32-4.5.2-20110712-1620-sfx.exe)

Extract DevKit to path C:\Ruby200\DevKit

Go to DevKit installation directory, cd C:\Ruby200\DevKit

Run the command ruby
dk.rb review

It is useful to review the list
of Rubies to be enhanced to use the DevKit and verify the changes you made to
it are correct.

Run ruby dk.rb install

  1. Run gem
    

update --system and run bundle install to your project folder.

Hope everything will go well while fixing these things. :smiley:

Thanks,

Vic

I've joked with people sometimes that the preferred deployment
strategy for Rails on Windows is a VM running Linux, but depending on
local politics, it may actually be worth considering. (Running a
database this way has significant performance penalties, as the
virtualization layer can make a hash of the DB's attempts to optimize
physical I/O, but even that may not matter for light or moderate
loads.)
