Hi, dudes  
I got a question here. When I run “rake db:migrate” in 3rdrail, it  
throws an error: D:\ruby\bin\ruby.exe: no Ruby script found in input  
(LoadError). I have set the ruby interpreter paths, And can’t find the  
solution on Google. Any good ideas?

Got the same problem, rails build is v20071130\_1710 and I’m using  
Instant Rails 2.0. This error occured after updating both to the  
currently newest version.

A workaround is calling “rake db:migrate” from the ruby console window  
from instant rails, i.e. not 3rdRails, so that the environment is set.

As far as I can tell, this is caused by the …/bin/rake file not having  
a  
��#! line.

So you should be able to add one, and continue as normal.

I get this using 3rdRail too, with this in …/bin/rake:

#!c:/Program Files/Ruby/bin/ruby.exe

# 

# This file was generated by RubyGems.

# 

# The application ‘rake’ is installed as part of a gem, and

# this file is here to facilitate running it.

# 

require ‘rubygems’

version = “\>= 0”

if ARGV.first =~ /^_(.\*)_$/ and Gem::Version.correct? $1 then  
version = $1  
ARGV.shift  
end

gem ‘rake’, version  
load ‘rake’

Just to be clear, by this I mean:

c:\Program Files\Ruby\bin\ruby.exe: no Ruby script found in input  
(LoadError)

when running the migration in 3rdRail.  
Running the same migration (i.e. rake db:migrate VERSION=001) from the  
command-line works fine though.
