Dirk80 has asked for the wisdom of the Perl Monks concerning the following question:

I try to install CPAN::Checksums 2.14 on a Windows 10 computer. I use Strawberry Perl v5.32.0. Please tell me if you need more information

As you can see below it seems to be a permission error when renaming a file. The permission to rename a file should be there.

By the way, command reports ANDK/CPAN-Checksums-2.14.tar.gz is not working for me because it is an offline CPAN.

Would be great if you could give me some hints how to solve it. Thank you!

    The test incorrectly assumes forward slashes everywhere. Maybe this part 
    like $cksum->{1}{cpan_path}, qr{t/tdir$},
        "cpan_path is as expected" or diag explain $cksum;

    [download]

    should be replaced with 

    my $path = File::Spec->catfile('t', 'tdir');
like $cksum->{1}{cpan_path}, qr{\Q$path\E$},
        "cpan_path is as expected" or diag explain $cksum;

    [download]

    or something similar.

    Update: Oh, we already have a function for that! So the first line should be 

        my $path = _d"t/tdir";

      Thank you very much. You fixed this test case. Now one more seems not work. Perhaps it's a similar thing.

      Perhaps it's a similar thing. But my knowledge is not enough to fix this error. This time a return value is not as expected. I'll give my best to look deeper into it. But of course I'd be glad to get some help. Thank you!

        At the point in the test folder t/tdir (or in Windows' speak t\tdir) still exists and contains three files: 1, 2, and CHECKSUMS

        At that point, that folder is not present when testing on Linux.

        I have no idea what that test is supposed to do exactly. An inserted rmtree _d"t/tdir"; did not cause the tests to PASS. I'll leave this to the Windows' experts.


        Enjoy, Have FUN! H.Merijn

Re: Installing of CPAN::Checksums 2.14 is not working

    Hi Dirk80

    I've tried to install the module on my windows. You have to modify several places if you want to pass all tests(and maybe use it on windows ;))
    1. modify test as choroba 's suggestion. Re: Installing of CPAN::Checksums 2.14 is not working
    2. the author use rename to move dir, sadly, it doesn't work on windows rename, so you have to replace rename with File::Copy::move or others( both on pm and t files)
    3. the author think \n is one byte, but it's 2 bytes on windows actually, so test for size of file 2 would be failed. maybe you should skip this test on windows
    4. delete the dir created by previously test manually, before you test again, otherwise the test will be failed. (when all tests passed, those dir will be deleted by tests. As Tux point out, inserting a rmtree statement at last is not a good idea.


    I am trying to improve my English skills, if you see a mistake please feel free to reply or /msg me a correction
