I'm going through Micheal Hart'ls Ruby on Rails 3rd Edition, on Cloud9 the Rails Server refuses to Start.
Ive tried many solutions offered by different websites but nothing worked. Please help - stuck in Chapter1 for the longest time
After putting the command "rails server -b $IP -p $PORT" on Cloud9 the following shows:
salsarkar:~/workspace/hello_app $ rails server -b $IP -p $PORT
=> Booting WEBrick
=> Rails 4.2.2 application starting in development on http://0.0.0.0:8080
=> Run `rails server -h` for more startup options
=> Ctrl-C to shutdown server
