Rails 2.3.4 Errors, :rails s && :bundle not workin

问题:

I have a friend who had an existing Rails application, which appears to be built in '2.3.4' according to the environment.rb files. He has some issues with it and asked me to look into it for him.

I am used to using Rails 3.2+.

I downloaded his files and ran the bundle command and got this response:

Could not locate Gemfile

I then tried to check out the site locally by running the rails s command. I got back:

Usage:
  rails new APP_PATH [options]

Options:
  -r, [--ruby=PATH]              # Path to the Ruby binary of your choice
                                 # Default: /Users/stevenbrooks1111/.rvm/rubies/ruby-1.9.3-p429/bin/ruby

                                 # Default: jquery
  -J, [--skip-javascript]        # Skip JavaScript files
      [--dev]                    # Setup the application with Gemfile pointing to your Rails checkout
      [--edge]                   # Setup the application with Gemfile pointing to Rails repository
  -T, [--skip-test-unit]         # Skip Test::Unit files
      [--rc=RC]                  # Path to file containing extra configuration options for rails command
      [--no-rc]                  # Skip loading of extra configuration options from .railsrc file

Runtime options:
  -f, [--force]    # Overwrite files that already exist
  -p, [--pretend]  # Run but do not make any changes
  -q, [--quiet]    # Suppress status output
  -s, [--skip]     # Skip files that already exist

Rails options:
  -h, [--help]     # Show this help message and quit
  -v, [--version]  # Show Rails version number and quit

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.
    See the README in the newly created application to get going.

I would like to be able to tell my friend what the issues are as well as go through the site. The server it was running on no longer accepts anything less than Rails 3.2.

How can I run this server locally? I cannot tell what the problems are because:

1. He doesn't have a gemfile.
2. I can't even see his site.
3. I cannot see where his errors are because he does not have any tests.

回答1:

bundle won't work. Rails 2.3 isn't integrated with bundler. rails s won't work either. In order to start the application server in Rails 2.3, you need to run

script/server

回答2:

Adding to the other answer, run ruby --version and gem list -d rails, to check you have the correct versions installed and on the paths. (I'm working on a Rails 2.3 project that got "too big to upgrade" these days!)
