Today, I met the following problem. I wrote an article, and use rake generate to generate the site. Then the console reports:

/home/chico/.rvm/rubies/ruby-1.9.2-p290/lib/ruby/1.9.1/psych.rb:148:in `parse’: couldn’t parse YAML at line 3 column 17 (Psych::SyntaxError)

why?
Then I found the reason:

“\“ should not be written in title of your article. If you really want to write it, use “\\“
