ytjPerl has asked for the wisdom of the Perl Monks concerning the following question:

Hi folks, I am facing an issue that I have no internet access on my VM, so when I running my perl script containing external modules, I have to manually copy *.pm from local machine to VM. For instance, I need to use File::Readbackwards. I have that locally at C:\Perl64\site\lib\File\Readbackwards.pm, but in my VM, I only have directory perl\site\lib(no sub-directory File), so I manually copied there, \Perl\lib\ as well. When I execute my script, it is still saying cannot locate File::Readbackwards. Please help! Thanks

    When your script tries to use File::Readbackwards, Perl looks in the directories in @INC to find a directory called File with a file Readbackwards.pm in it. Just make it so :-)


    The way forward always starts with a minimal test.

      I already put ReadBackwards.pm at location \perl\site\lib and \perl\lib, but still not working.

        As was already explained, that file needs to go into a directory called 'File' -- so you should move the file ReadBackwards.pm from \perl\site\lib to the new location \perl\site\lib\File. (Hint: you may need to create that directory.)

    As already mentioned by other monks, it should be in your @INC. You can check if the required dirs are in it. 
    use Data::Dumper;
print STDERR Dumper( \@INC );

    If it's not there, the module won't be found. You can add it to the @INC with: 
    sub BEGIN {
    unshift @INC, 'c:/Perl64/site/lib';
    unshift @INC, 'c:/.....';    # what ever you needed
}

    BTW, it should be '/' and not '\' in your script.

    Hi ytjPerl,

    try this:

    1. Download the tarball from CPAN to your local machine File-ReadBackwards
    2. Copy the tarball from your local machine to your VM
    3. Install the module manually on your VM Installing Modules

    Hi,

    Instead of trying to copy a few module .pm files, why not copy the entire perl directory?

    Additional consideration on Windows: xcopy /D will only copy updated files.
