it seems im either missing a library or i am having a problem in my configurat
There is another instance of webrick running of the port 3000. Use the command
ps aux | grep webrick
To verify it. And then kill it.
EDIT:
The ps command shows you a list of the current running programs of your machine. Each program on a unix-like machine comes with a PID number associated with it. In your case, the other running instance has a pid = 12288. So you can use:
kill 12288
To kill the other instance of the server.

I got the same error when tried to start my Sinatra app on cloud9. It turned out that I was running the command : $ bundle exec rackup -p $PORT -o $IP with root user (su). Try to run it on normal user.
You have a dash before ip and port arguments. The values of the arguments are specified without dashes. Try:
rails s -b $IP -p $PORT
https://www.railstutorial.org/book/beginning#sec-rails_server
I have reached this step, and I'm using the cloud9 environment. When I run the server as per Listing 1.7 on that tutorial, however, I get this error:

I've tried specifying a different port, but that doesn't work and the cloud9 environment suggests to me I should just use the $PORT variable.
The error "Address already in use - bind(2) for 0.0.0.0:8080 (Errno::EADDRINUSE)" implies that I already have a rails server running, but I don't. I'm not really sure what to do here and the tutorial doesn't suggest any method of troubleshooting this issue.
I learned that you can use the command killall ruby to stop any of the ruby processes which helped me because I had mistakenly run the rails server -b $IP -p $PORT command at the ~/workspace level in the tutorial. I found the answer in can't open rails server
I ended up starting the tutorial from scratch again and it worked fine, but anyone with this problem in the future may find this troubleshooting technique I received from cloud9's support team useful:
Try:
lsof -i:8080
This will give the app that occupies it.
If apache, stop it using:
sudo /etc/init.d/apache2 stop
Hope this answer is of use to anyone with this problem.
Probably you just had the other server still running. The one you initiate earlier on in he tutorial with the rails server command. You need to shut the other one down first using Ctrl+C, then try rails server -b $IP -p $PORT again
$ rails server -b $IP -p $PORT
Cloud9 uses the special environment variables $IP and $PORT to assign
the IP address and port number dynamically. If you want to see the
values of these variables, type echo $IP or echo $PORT at the command
line.
It's likely that if you wait a few minutes (not more than 2), your OS will free up the port. If not, use a random port number over about 5,000 every time you run rails server, e.g.
$ rails server -b $IP -p 6789
Or, because your IDE is so sucky, you might consider using a different IDE.

Something happened to the ODBC data source somehow. Our ODBC data source had been 64-bit for weeks, but for the app to work again, I had to create a 32-bit data source using C:\Windows\SysWOW64\odbcad32.exe.
I'm trying to create a very simple Hello, world program in RoR, but when I go to view the url http://localhost:3000/say/hello I'm getting the error message No route matches: "say/hello"

I started with: rails generate controller Say hello goodbye
which lists route get "say/hello"
Also: I'm having this problem which is probably related. When I go to write some basic html in one of the files that is clearly listed as existing I get this:
I write this:
~/work/demo$ /app/views/say/hello.html.erb
Get this error message in return:
bash: /app/views/say/hello.html.erb: No such file or directory
What's going on here? I'm getting these instructions straight from Agile Development with Rails and it's so simple. I don't understand what's going on.
[2011-06-20 20:02:44] WARN TCPServer Error: Address already in use - bind(2)
You already have a server (or something) running on the port your server is supposed to be running on. As such, the code you think is running (which you say has the route in question) actually isn't running. Once you shut down the other process (probably a previously running rails server?), you can start the correct one and make sure it actually has that route.
The error you're getting at rails startup indicates that there is already a server running at port 3000 on your machine (and apparently that server knows nothing of a "say/hello" route). Shut that one down and try again.
The second error is because from bash the path / goes to the root directory. Try:
cat app/views/say/hello.html.erb
I am faced with a similar problem. In my case after $ rails server command I am unable to shut down the server using ctrl-C in the terminal itself. Nothing happens when I press ctrl-C in the terminal.
When I reopen the project on another terminal, and run it again I get the following message:

In essence I have to kill the process from system monitor everytime. Can this be cured?
On a mac, type the following in your terminal:
lsof | grep IPv4
or
lsof|grep 3000 in linux i think.
find the lione that starts with 'ruby' and note the number next to that.
let's say the number is 1234. type the following in you terminal:
kill -9 1234
and you should be right. Remember to exit out of WEBrick with control-c!
I'm trying to get started with Ruby on Rails, and it's all gone quite well up until I try to start the server. I get the following error:
C:\Users\Ken\workspace\railsHello>rails server

I don't even know where to start with "TCPServer Error: Not a socket file descriptor."
Trying it through Aptana didn't help either.
I'm on Windows 7 Home Premium. Apache was already installed, but I shut it down and it didn't make a difference.
Thanks in advance for your help!

Are you sure nothing else is listening on port 3000 (perhaps an old instance of the server that didn't get shut down)? Check the following:
netstat -a -b
If there is, simply kill that application, or start WEBrick on another port; for example, to start it on port 8000:
rails server --port=8000
