How to specify thin to use Rack adapter rather than Rails adapter when starting

Question

I am using Capistrano to deploy an app. The following command works if I enter it at the terminal via SSH:
thin start -p 20480 -e production -d

But when it is ran through Capfile like:
run "cd #{current_path} && thin start -p 20480 -e production -d"

It has this error in the log:

Writing PID to tmp/pids/thin.pid
Using rails adapter
Exiting!
/usr/local/rvm/rubies/ruby-1.8.6-p369/lib/ruby/1.8/yaml.rb:133:in load': syntax error on line 2, col 8: specs:' (ArgumentError)

The difference is the second lin: Using rails adapter. When I enter this command at the terminal by myself, it says Using Rack adapter.

Any idea how to fix this? Thanks a lot for any suggestions.

Best regards, Tony.

Try stating explicitly whant adapter you want to use. You can do this using the --adapter switch. So your line of code will look like this:

run "cd #{current_path} && thin start -p 20480 -e production -d --adapter rack"

Maybe this helps.

thin --help says:

-A, --adapter NAME   Rack adapter to use (default: autodetect)
