我错过了什么？我哪里出错了？如何使用XPath.pm？如何将其包含在perl脚本中？

尝试将XPATEngine放在C:\dwimpel\perl\site\lib\XML文件夹中

使用cpan命令而不是复制文件。

    Can't locate XML/XPathEngine.pm in @INC (@INC contains: /perl/site/lib C:/Dwimpe
rl/perl/site/lib C:/Dwimperl/perl/vendor/lib C:/Dwimperl/perl/lib .) at C:/Dwimp
erl/perl/site/lib/XPath.pm line 103.
BEGIN failed--compilation aborted at C:/Dwimperl/perl/site/lib/XPath.pm line 103
.
Compilation failed in require at Multi_instance_run1.pl line 9.
BEGIN failed--compilation aborted at Multi_instance_run1.pl line 9.

 - In perl script, used like require XPath;
 - After that executed command cpan XML::XPath .
 -I've copied following files in the path C:\Dwimperl\perl\site\lib
              XPath.pm
              XPathEngine.pm
