can't activate rails (= 2.2.2, runtime), already activated rails-2.3.2

Hi,

I have updated from Ruby on Rails 2.2.2 to 2.3.2. I have managed to run it both on my Mac OS X and Ubuntu server. (script/server -e production)

But when I tried to run it using Capistrano, I got an error. (cap deploy:start). (I replaced my home directory name etc. with --- in the following):

*** [err :: ---.org] /usr/local/lib/site_ruby/1.8/rubygems.rb:149:in `activate' *** [err :: ---.org] : *** [err :: ---.org] can't activate rails (= 2.2.2, runtime), already activated rails-2.3.2 *** [err :: ---.org] ( *** [err :: ---.org] Gem::Exception *** [err :: ---.org] ) *** [err :: ---.org] from /usr/local/lib/site_ruby/1.8/rubygems/ custom_require.rb:35:in `require' *** [err :: ---.org] from /home/----/public_html/----.ca/current/ script/process/spawner:3

In Capfile, I commented out the line: Dir['vendor/plugins/*/recipes/*.rb'].each { |plugin| load(plugin) } because I thought a plugin may be requiring Ruby on Rails 2.2.2. But still same error showed up.

Has anybody encountered this problem?

When I start with "script/server -e production", there is no problem and the application is running without a problem. So I doubt that it's a problem of some gem requiring Ruby on Rails 2.2.2.

Maybe it's a problem only with Capistrano and it may not be related to this mailinglist.

But any help will be greatly appreciated.

Hi,

It turned out that commands/process/spawner that is used by Capistrano was deprecated in Ruby on Rails 2.3.2. And it was extracted to irs_process_scripts plugin. (http://github.com/rails/irs_process_scripts/tree/master)

After I installed the plugin (script/plugin install git://github.com/rails/irs_process_scripts.git), the error stopped occurring and Capistrano worked as before.

Thank you.

Sincerely, Tadatoshi

Beware that the install script for this plugin clobbers everything in script/process, including any .svn directory (as I just found out).

Better to manual install.....
