Rails server does not run


#1

whenever I type : rails server -b $IP -p $PORT
into the terminal window, I get a report on the proper usage of ‘rails new’


#2

You must be in your rails project root dir to run that command.
If you created your rails project with rails new someproject when your terminal was at (username):~/workspace, then your project was created in its own directory.

So you must go into your project directory : cd someproject
before running rails : rails server -b $IP -p $PORT

HTH, Eric

Perfect, thanks, Eric.


#4

I am getting this same error. I am in my project directory. Did ‘ls’ see the files, also git push etc, tried restarting the workspace and the error is not going away.

My workspace (username):~/workspace/myproject (master) rails s -b $IP -p $PORT
Gives me a page that looks like I typed rails. It is if the console does not read past the word rails.

For a test, I entered rails g controller Test and got the same result.

Description:
The ‘rails new’ command creates a new Rails application with a default
directory structure and configuration at the path you specify.

You can specify extra command-line arguments to be used every time
'rails new' runs in the .railsrc configuration file in your home directory.

Note that the arguments specified in the .railsrc file don't affect the
defaults values shown above in this help message.

Example:
rails new ~/Code/Ruby/weblog

This generates a skeletal Rails installation in ~/Code/Ruby/weblog.

What does ruby -v and rails -v gives you ? can you show the result of pwd && ls ?

When you run your server with rails s -p $PORT -b $IP, what is the result ? (please encapsulate the result with ```)


#7

Sorry for the late reply. The problem still exists.
Here is the info.
ruby -v is … ruby 2.4.0p0 (2016-12-24 revision 57164) [x86_64-linux]
pwd && ls result … pwd && ls
/home/ubuntu/workspace/funnycars
Capfile Gemfile Gemfile.lock README.md Rakefile app/ config/ config.ru db/ lib/ log/ note.txt package.json public/ shared/ test/ tmp/ vendor/

Running rails s -p $PORT -b $IP result is

Hi @TazzyG, sorry for the late answer, I have not been informed you answered me.

It seems you are inside your project with a rails app as you have the good folders (Capfile Gemfile Gemfile.lock README.md Rakefile app/ config/ config.ru db/ lib/ log/ note.txt package.json public/ shared/ test/ tmp/ vendor/ but rails do not understand it.

Maybe it’s a rails version conflict, try using the full command bundle exec rails s -p $PORT -b $IP

Or maybe your path is not using the good rails ; did you used rvm to install it ?
Typing rails -v && which rails should give you something like

Rails 5.1.4
/usr/local/rvm/gems/ruby-2.4.1/bin/rails
