strange inability to require config/boot after upgrading to ruby 1.9.2

Question

I upgraded my ruby to 1.9.2 and now when I try to start up a Rails 2.3.5 app with script/server I get this error:

Answer 1

The $: << File.dirname(__File__) + '..' won't work since you'd get a dir of

'script..'

Try

$: << File.join(File.dirname(__FILE__),'..')

Answer 2

Please check your root path before start padrino. like if your application in "C:\XXXXXXX\YYYYYYY\ZZZ-padrino" here and you are in "C:\XXXXXXX\YYYYYYY\" in command prompt then this error will occur. then you should in "C:\XXXXXXX\YYYYYYY\ZZZ-padrino".

Answer 3

You might try to add the path source /usr/share/ruby-rvm/scripts/rvm

Answer 4

Much simpler, does not require modification of all scripts:

Instead of:

script/server 

call:

./script/server

Answer 5

it's because ruby 1.9.2 doesn't add the current directory in the LOAD_PATH.

Add this that in top of your script/server file:

$: << File.dirname(__FILE__)

Or in your case:

$: << File.dirname(__FILE__) + '..'

Answer 6

Replacing line 2 of script/server with

require File.expand_path('../../config/boot', __FILE__)

works for me (taken from Rails 3)
