"script/* replaced by script/rails" not working

Reported by Nick Clarke | February 5th, 2010 @ 12:56 PM | in 3.0.2


I just installed the new beta version of rails 3 and ran into a error with the new script/rails commands.

I'm running:
Windows 7 64bit
ruby 1.9.1p243 (2009-07-16 revision 24175) [i386-mingw32] (One Click installer)

Below are the steps I did:

  C:\Users\username\Documents>cd v3app

Now when I run any of the following commands I see the same error:

  C:\Users\username\Documents\v3app>rails --help
  C:\Users\username\Documents\v3app>rails console
  C:\Users\username\Documents\v3app>rails g scaffold post title:string

all generate the following error:

  C:/Ruby19/lib/ruby/gems/1.9.1/gems/railties-3.0.0.beta/bin/rails:2: command not

    I can reproduce this problem on my Windows XP box with Rails 3.0.0.beta, but instead of getting an Errno::ENOENT, I am getting an Errn
    o::ENOEXEC. Nonetheless there seems to be an issue with the exec() call in file <MY_RUBY_INSTALL>/lib/ruby/gems/1.8/gems/railties-3.0.0.beta/bin/rails on line 2.

    I was able to fix this by changing the file on line 2 into the following: exec('ruby', Dir.getwd + '/script/rails', *ARGV)

    Hope this helps.

    Torsten Maul's fix works under Ruby 1.8.7, but not using 1.9.1.

    Windows-users forced to stay in 1.8.7 then I guess.

    That fix worked for me on WinXP Pro using 1.9.1 RC2 from For his fix to work, ruby has to be in your path. Instead of 'rails server' from the root of your new rails app, what do you get if you type 'ruby script\rails server'?

    My bad, the fix indeed works on Windows with Ruby 1.9.1. Though you get problems with invalid .gemspecs (related to Bundler). Mentioned and fixed in Next version of Bundler should fix that.

    Thanks Torsten for the fix.

    It seemed to work but I also now get the same issue that Fredrik mentions inc the massive error output.

    I'll keep an eye on the Bundler update and will retest once it is released.

    The fix from Torsten works also for me but with some addition.
    In my case, 'ruby' is not the name of my executable. It is ruby18.

    I've replaced the second line of the file:
    exec(Dir.getwd + '/script/rails', *ARGV)

    with the following which is safer regarding the name of the ruby executable name:
    require 'rbconfig'
    ruby_exe = Config::CONFIG["ruby_install_name"]
    exec(ruby_exe, Dir.getwd + '/script/rails', *ARGV)

    Another solution is to replace:

    2: exec(Dir.getwd + '/script/rails', *ARGV)


    2: load(Dir.getwd + '/script/rails')

    This solution was posted in the comments of the official beta release announcement by @Trys. At first glance, I didn't think it would work for cases like:

    rails generate scaffold log entry:string

    because it doesn't explicitly pass the arguments along but it has worked perfectly in every case that I've tried so far.

    Using load is definitely a much simpler solution but I'm not sure if it is a better solution than others that have been proposed. Thoughts?
