ROR setup on ubuntu machine

i followed this Ruby in Twenty Minutes, and setup all the stuffs. After i created a new rails application, when i create a database i got one error like cyberpro@ubuntu:~/blog$ rake db:create rake aborted! Could not find a JavaScript runtime. See https://github.com/sstephenson/execjs for a list of available runtimes. (See full trace by running task with --trace)

Try this:

Thanks for the response. i think this question, which am going to put here, is a bad question, anyway when i start the server cyberpro@ubuntu:~/blog$ rails server /home/cyberpro/.rvm/gems/ruby-1.9.2-p290/gems/rack-1.3.4/lib/rack/backports/uri/common_192.rb:53: warning: already initialized constant WFKV_ => Booting WEBrick => Rails 3.1.1 application starting in development on http://0.0.0.0:3000 => Call with -d to detach => Ctrl-C to shutdown server [2011-10-12 15:15:12] INFO WEBrick 1.3.1 [2011-10-12 15:15:12] INFO ruby 1.9.2 (2011-07-09) [i686-linux] [2011-10-12 15:15:12] INFO WEBrick::HTTPServer#start: pid=9007 port=3000 my question is, how to move to the db creation ? i mean how to stop this. can i use this Call with -d to detach => Ctrl-C to shutdown server and continue…

Am sorry for asking this type of question

Couldn't disagree more. RVM actually makes like a lot easier for beginners IMO. The install is simple and easy (just run the script) and works perfectly fine on pretty much any version of Ubuntu.

Using RVM allows beginners to tinker with various versions of Ruby in a non-traumatic way and keeps each project in its own gemset to avoid version conflicts and issues with dependencies. Once installed correctly, with wrappers in place, it works identical to native ruby only you don't have to "sudo" so much.

It's a great place to both start and finish as a ruby developer. I run RVM locally and in production and I advise all the newbies I help out to do the same. Particularly on an OS X dev environment, native ruby is a pain and RVM alleviates most of those pain points.

Work through some tutorials that will show you the basics of Rails. railstutorial.org is good and is free to use online. Then you will look back on the questions you are asking and not believe that you had to ask them :slight_smile:

Also look at the Rails Guides.

If you want to stop WEBrick server then use CTRL+C (if that doesn’t work try CTRL+Z).

OR, you can open another terminal window and work there to create your database (I recommend that).

Thanks all, thanks mg1313

Advanced thanks to all, for given some important links, which help me a lot, to start the ROR from scratch. After all the set-up, I have created one page. so next i need to integrate a simple application with twitter. Simple application means when i write something in a text box and click the button, that will update into my twitter account. for that i have to use the twitter apis for the authentication purpose, i have got the token from twitter. But i have some confusing how to use it, And also this rails basically going with MVC. so where the code will write? and so on… I knw the MODEL is basically connection with the database, and the VIEW for the presentation. and finally the CONTROLLER have the main function part. But where will write the code for each one? If have any mistake in my understand, plz specify the issues?

also i got some link about dis Integrating Rails with Twitter | Pedro Mateus Tavares

Thanks Vishnu

Have you worked right through some tutorials such as railstutorial.org? This will answer most of these questions.

rvm > apt

I really like using rvm for different gemsets. When you want to test out the latest version of rails for 1 project it makes life so much easier. apt and rvm have declared a delicate truce on my machine. I basically use apt for system wide packages and rvm for ruby and rails so that I can have different versions on different projects.

I followed this link for integrate with twittter http://cbpowell.wordpress.com/2011/03/17/twitter-oauth-and-ruby-on-rails-integrated-cookbook-style-in-the-console-updated-for-twitter-1-0/ but when i give this in console i got the error like this

I suggest starting a new thread with an appropriate subject for this question as it does not seem to be anything to do with the subject line (ROR setup on ubuntu machine). In that way someone interested in this subject is more likely to read the message.

i had some problem with my ubuntu, so just i changed that into 11.10, now am setting up the RoR in ubuntu following this link http://ryanbigg.com/2010/12/ubuntu-ruby-rvm-rails-and-you/ . But i got the wrong command error when i doing this command ** sudo aptitude install build-essential bison openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-0 libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf**

COMMAND NOT FOUND.

why like dis?, but i had done the same thing earlier on my last ubuntu with no issues.

Thank You Vishnu

Which command is not found?

Did you tried Europe apt-get install instead?

Or installed aptitude via apt-get?

thank you, i forgot to change that aptitude into apt-get.

Thank you vishnu

or you can install aptitude using

sudo apt-get install aptitude

and then use it later...
