But when i want to start the server using :

C:\ruby\bin\newproj>ruby script/server
output is: ruby: No such file or directory -- script/server (LoadError)

C:\ruby\bin\newproj>ruby script\server
output is : ruby: No such file or directory -- script/server (LoadError)

Is it because create script/server does not feature in the above list??
I'm helpless....Plz help me start RoR....

run “rails s”
You are on rails 3 man please read the latest Docs

Hi, in Rails 3 there is no more script/server. You can start your server
with 'ruby rails server' oder just 'ruby rails s'.

Good luck, Max.

Thanks Rajeev and Max.

But how do i know if the server has started??
The output says a lot of things but not if the server has started

May you guys pls send me links to the latest docs for Rails 3.0?/
I'm totally new to RoR..

I tried with the Head first books but cudn't get thru!!!

Thanks,
Premanshu

Google “rails”

But since you’re just starting off with Rails, I would advise you to simply run a Ubuntu Linux virtual machine (or even completely switch to Linux right away) instead of frustrating yourself with Windows problems and avoid even more issues with native library gems in the future.

Hi Peter,

I m running Java VM on my system. Is there any luck with WIndows that i
can expect of.....???

I need to deliver a few projects pity quick and thats why i thought RoR
would come handy....
Pls put your helping hands together...

Premanshu

You could run your Rails app under JRuby if you like, but that would mean using the Java MySQL drivers instead. Java VM and a VMWare virtual machine are two different things though.

You should start researching those things yourself though, since running through a whole Rails stack is out of the scope of this mailing list. Google is your friend.

Best regards

Peter De Berdt

Yes, in fact JRuby is a good option on Windows. Download the latest
version of NetBeans, which comes with JRuby, and you should be able to
get a Rails app up and running fairly quickly.

@Peter, Mark, Marnem: Thanks guys for the posts
I have kick started my first project.But on windows and that on a
sqlite3 db. I tried hard to get mysql but somehow its not willing to
dance with the rails on Windows platform. But still I would try out my
luck with JRuby on windows and later on if i can survive RoR i will
shift to Linux....

But if any body pokes in the direction of how to make MySQL work with
Rails on windows would be like an angel...

hope to get further guidance from Railers.

Many thanks,

A number of Ruby gems like the mysql2 gem are built with extensions written in C, which means they need a properly configured compiler and tool chain on the computer they’re being installed on; without it the build process fails and the gem doesn’t install correctly.

These things are standard on Linux installations of course, but not in Windows. However the guys at the RubyInstaller project have put together a development kit for Windows so that gems with native extensions will compile. Go here:
http://rubyinstaller.org/add-ons/devkit/ for the project page and here:
http://github.com/oneclick/rubyinstaller/wiki/Development-Kit for the installation instructions.

Once you have the DevKit installed, re-run “bundle install” and hopefully the mysql2 gem should now install properly.
