本文介绍了一种解决在运行脚本时遇到的关于XMLSimple.rb重复初始化常量警告的方法。该问题虽然不影响功能但令人烦恼。通过调整文件链接和加载方式，可以有效消除这些警告。

Hi All,

Anyone know how to fix the below warnings which I get when I run most
if not all of the ./script executables, some googling reveals the odd
mention of it but I haven't seen a good fix for it.

It's not causing any functional issues for me (so far), just damn
annoying..

Thanks,
Stephen

解决办法：

I found the problem on my system to be slightly different than the one
described in the link. The
conflict was due to xmlsimple.rb being included as well as lib/
xmlsimple.rb which is nothing more
than a link to the original file.

The following script worked for me:

#!/bin/sh

cd /usr/lib/ruby/1.8
if [ -h lib/xmlsimple.rb ]
then
mv lib/xmlsimple.rb lib/xmlsimple.rb.old
mv xmlsimple.rb lib/.
cat > xmlsimple.rb <<!
require 'lib/xmlsimple.rb'
!
else
echo `pwd`/lib/xmlsimple.rb is not a link. Exiting.
