Strawberry perl: none File :: Tail.pm. CPAN could not install the module

Question

I use strawberry perl to tail the file using File::Tail .

I got an error message:

Cannot find file /Tail.pm in @INC (@INC contains: c: \ strawberry \ perl \ lib C: / strawberry / perl / site / lib C: / strawberry / perl / vendor / lib C: / strawberry / Perl / lib.) in the line tailing.perl 5. BEGIN failed - compilation was canceled on the line tailing.perl 5.

Three packages contain lib:

• c:\strawberry\perl\lib
• C:\strawberry\perl\site\lib
• C:\strawberry\perl\vendor\lib

where c:\strawberry\perl is the root directory of the perl installation.
I checked all three packages, but could not find File/Tail.pm

Using cpan install, but the installation failed.

Answer 1

In the current File::Tail distribution on CPAN, he never transferred his test suite to Windows . Steffen Mueller introduced the patch for Windows 5 years ago, but it was never included in the CPAN distribution.

His patch is available here , and hallelujah, it works for me. Just unzip it anywhere and run the usual

 perl Makefile.PL dmake dmake test dmake install 

Answer 2

This is a great thing about Strawberry Perl.

 C:\Users\me > cpan File::Tail 

Of course I got:

Therefore, I would not recommend it.

Not all modules are part of the standard set of modules. You should check the Perloc Perl documentation. It contains all the standard Perl modules. If the module is not there, you must install it.

As Axeman said, you can use the cpan command to install any module. Just type cpan at the command line, and when you get the cpan> prompt, type install File::Tail . It should automatically install everything for you, including prerequisites.

You can also see module reviews on CPAN Ratings .
