Puppet起動したら「Warning already initialized constant」

たぶんdebian/ubuntu特有のWarning

/usr/lib/ruby/1.8/xmlsimple.rb:275: warning: already initialized constant KNOWN_OPTIONS
/usr/lib/ruby/1.8/xmlsimple.rb:280: warning: already initialized constant DEF_KEY_ATTRIBUTES
/usr/lib/ruby/1.8/xmlsimple.rb:281: warning: already initialized constant DEF_ROOT_NAME
/usr/lib/ruby/1.8/xmlsimple.rb:282: warning: already initialized constant DEF_CONTENT_KEY
/usr/lib/ruby/1.8/xmlsimple.rb:283: warning: already initialized constant DEF_XML_DECLARATION
/usr/lib/ruby/1.8/xmlsimple.rb:284: warning: already initialized constant DEF_ANONYMOUS_TAG
/usr/lib/ruby/1.8/xmlsimple.rb:285: warning: already initialized constant DEF_FORCE_ARRAY

/usr/lib/ruby/1.8/xmlsimple.rb:287: warning: already initialized constant DEF_KEY_TO_SYMBOL

xmlsimpleが、自分自身require を内部的に行うが、rubyのインクルードパスが衝突して2重ロードになっていた。うざい。

対応　余分なxmlsimple.rb　を消す

重複してそうなファイルを移動させた。

takuya@colinux:$ sudo mv /usr/lib/ruby/1.8/lib/xmlsimple.rb /usr/lib/ruby/1.8/lib/xmlsimple.rb.bak 

エラーでなくなった。どこが余分か調べる。

/usr/lib/ruby/1.8/lib/xmlsimple.rb

  1 require File.dirname(__FILE__) + '/../xmlsimple.rb'
