Don't know how to build task 'add_new_scripts'


Looking at my changelog, it appears I’m using Rails 0.14.2, so I tried
to upgrade by doing:

$ rake update_javascripts
(in /var/www/html/rails)
$ rake add_new_scripts
(in /var/www/html/rails)
rake aborted!
Don’t know how to build task ‘add_new_scripts’

Any help?

I ran into this too…until I went back and actually read the
instructions on how
to upgrade from 0.13.x to 0.14.x. In a nutshell you need to do the

  1. copy your app to another directory, unless you have it under version
  2. go into your app directory and run ‘rails .’ to build a 0.14.x app
  3. compare the various config files of the new version to your old
    adding in any changes you made to the stock configuration
  4. then run the update_javascripts and add_new_scripts commands.

Hope that helps. Here’s the URL for the full instructions
