Rails 3-psych.rb-无法解析YAML

Question

While integrating backgroundrb-rails3 I get the following error,

~/.rvm/rubies/ruby-1.9.2-p290/lib/ruby/1.9.1/psych.rb:148:in `parse': couldn't parse YAML at line 8 column 22 (Psych::SyntaxError)

I found a similar question in stack overflow and the accepted answer works for me.

I don't want to use Syck, how can i fix it with Psych? Is there any difference in yml format for both? As the backtrace is not pointing to any yaml file, how can i debug more?

Any help is highly appreciated...

Ok, it looks like Psych can't parse this specific line from the default configuration:

:trigger_args: */5 * * * * * *

Wrapping the conditions in quotes should fix it:

:trigger_args: "*/5 * * * * * *"

You can copy the default config into your config folder and make this change there. Here is the exact file to use: https://raw.github.com/mtylty/backgroundrb-rails3/master/config/backgroundrb.yml
