Module installed with cpan isn't showing up

问题

I'm trying to install Array::Iterator and Text::ParseWords using cpan. I'm on OSX with cpan v1.61 and perl v5.18.2.

When I start up cpan, after the initial configuration, I type install "Array::Iterator" and it seems to install correctly. But when I try to run my perl script with use Array::Iterator, I get:

Can't locate Array/Iterator.pm in @INC (you may need to install the Array::Iterator module) (@INC contains: /Library/Perl/5.18/darwin-thread-multi-2level /Library/Perl/5.18 /Network/Library/Perl/5.18/darwin-thread-multi-2level /Network/Library/Perl/5.18 /Library/Perl/Updates/5.18.2 /System/Library/Perl/5.18/darwin-thread-multi-2level /System/Library/Perl/5.18 /System/Library/Perl/Extras/5.18/darwin-thread-multi-2level /System/Library/Perl/Extras/5.18 .) at ./parse.pl line 7.

    main::BEGIN() called at ./parse.pl line 7
    eval {...} called at ./parse.pl line 7
BEGIN failed--compilation aborted at ./parse.pl line 7.
 at ./parse.pl line 7.

Line 7 is:

use Array::Iterator;

回答1:

Add the complete PATH where your Array::Iterator pm file is located Use the below code in start of the script after shebang line may be the path is not loaded

BEGIN { push( @INC, 'PATH' ) }
