i’ve a cgi wanted to make use of yaml and i get this error reported by Apache2 : [Tue May 06 12:25:50 2008] [error] mod\_ruby: error in ruby [Tue May 06 12:25:50 2008] [error] mod\_ruby: /opt/local/lib/ruby/1.8/yaml.rb:133:in `load': syntax error on line 3, col -1:` manpath: “” (ArgumentError) [Tue May 06 12:25:50 2008] [error] mod\_ruby: search: man [Tue May 06 12:25:50 2008] [error] mod\_ruby: section: “” [Tue May 06 12:25:50 2008] [error] mod\_ruby: : 1 [Tue May 06 12:25:50 2008] [error] mod\_ruby: [Tue May 06 12:25:50 2008] [error] mod\_ruby: yaml: /Users/yt/Sites/man/man\_rep/history.yaml [Tue May 06 12:25:50 2008] [error] mod\_ruby: ’ [Tue May 06 12:25:50 2008] [error] mod\_ruby: from /opt/local/lib/ruby/1.8/yaml.rb:133:in `load' [Tue May 06 12:25:50 2008] [error] mod_ruby: from /Users/yt/Sites/man/index.rbx:30 [Tue May 06 12:25:50 2008] [error] mod_ruby: from /opt/local/lib/ruby/1.8/apache/ruby-run.rb:53:in`load’ [Tue May 06 12:25:50 2008] [error] mod\_ruby: from /opt/local/lib/ruby/1.8/apache/ruby-run.rb:53:in `handler’ the calling line being : history=YAML::load( File.open( YAMLFILE ) ) and the yaml file being no more than : — history.yaml ------------------------------ — !ruby/object:History items: !ruby/object:Item ? manpath: “” search: man section: “” : 1 yaml: /Users/yt/Sites/man/man\_rep/history.yaml — history.yaml ------------------------------ I should mention i don’t have prob when testing that apart from Apache2 and cgi. When testing under Apache2/cgi my requirements are : require ‘rubygems’ require ‘cgi’ require ‘fileutils’ require ‘yaml’ require ‘history’ When testing standalone: require ‘rubygems’ require ‘yaml’ require ‘history’ the ‘history’ script being a class History of mine, nothing to do (i believe) with the prob. ---

YES, because of “rubygems” i’ve tried : require ‘man\_rep/manpage’ require ‘rubygems’ require ‘cgi’ require ‘yaml’ =\> that way probs with yaml require ‘rubygems’ require ‘yaml’ require ‘cgi’ require ‘man\_rep/manpage’ =\> that way probs with rubygems (unable to find man\_rep/manpage …) but i could try something else, using “computed” absolute path for ‘man\_rep/manpage’ thanks for your answer ! ---
