Excellent work Aslam, I came to know about this site via änthräX blog. Keep up good work. :)

It’s better if you could increase audio volume level in your next screencasts. My laptop can’t produce much sound, and I can’t hear you clearly.

I have a one question also. Why does the following command take a longer time (more than apt-get or yum) to execute?
sudo gem install rails

Thank you very much for this screencast.
(I’m totally new to ruby)

Thank you for your feedback Shaakunthala!

Yeah, I agree. I’ll increase the volume in upcomming screencasts. Also I would like to give the original high quality video to download very soon.
I hope you can hear clearly in the original video. :)

The answer to your question is,

apt-get and yum will install bunch of file one by one like a queue and displays the downloading file and the state in terminal.

But in the case of Rails installation, you are actually installing different 7 number of gems, rake, activesupport, activerecord and so on. You need all these gems to create and run Rails apps. During the Rails installation process you can see, it’ll only prompt when a gem successfully installed.Unlike apt-get and yum it wont show downloading files one by one. So, It looks like long process.

Welcome to the Ruby word! :)

Great job Aslam!.. It totally worked for me. I was trying to develop a Ruby client for Apache ActiveMq broker. This was really helpful to me…

@Shaakunthala:
You can add –no-ri and –no-rdoc to avoid installing the online documentation for the gems. But this is not recommended if you plan to defer to the documentation. (ri and rdoc are similar to man pages and javadoc). Avoiding them however speeds up the gem installation.
Eg: sudo gem install –no-ri –no-rdoc rails

Corrections to my last comment, sorry.

1. I meant “refer the documentation” not “defer to the”. :)
2. And the characters before the no-ri and no-rdoc options are double dashes (- -) without a space in between. It might not be obvious in the comment.

I went through everything on the screencast just fine, until I went to install rails, and got this message:

Seems that your Ruby interpreter cannot understand the ‘require’ keyword. This may happen if your installation failed before the completion.
Remove Ruby totally from your computer and then do a fresh installation. Make sure your internet connection during the installation.

Nice post. Iam new to ubuntu(Linux) and your screencast eased my way for my setting up the RoR environment.

Very helpful screencast! Your instructions worked perfectly for me on Ubuntu 10.04 LTS. Thank you

http://mohamedaslam.com Aslam

Hey Eric.

Glad the screencast helped you with the installation. I’m planning to do a new screencast on Ruby on Rails installation with RVM on Ubuntu.

Stay tuend.

Great work Aslam. finally got it running! It is “rails server” for me ubuntu 10.04 rather than ./script/server to run the application otherwise everything is 100% spot on. Thanks.

http://mohamedaslam.com Aslam

Hello Kabir,
Thanks for the comment.

If you follow the instruction above, now it’ll install Rails 3.0 rather than Rails 2.3.x
That’s why you need to use “rails server” instead of “./script/server”

I hope to write a new guide for Rails 3.0 stay tuned.
