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.

Tadatoshi

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.  
([GitHub - rails/irs\_process\_scripts: WARNING: this repo is not maintained anymore, if you want to maintain it, please send an mail to rails-core. The extracted inspector, reaper, and spawner scripts from script/process/\*](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…
