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

I'm trying to manually install the DBI module from CPAN using the command prompt on Windows 10.

After I downloaded the zip file in CPAN, I extracted it to the C: directory. When I typed in C:>cpan Module::DBI in the command prompt, it shows this line of error:

"Warning: Cannot install Module::DBI, don't know what it is"

What am I doing wrong?

************************************************************** MAJOR UPDATE************************************************************

I found out that the Strawberry installed in my computer is an old version.
So, I uninstalled it, downloaded and installed the latest version

And then, I successfully installed the DBI module

I'm sorry for wasting your time. Thank you very much for your help.

    Strawberry perl already ships with DBI, should you wish to upgrade it to a more recent version simply run the following from the command prompt:

    cpanm DBI

    [download]

    Note cpanm rather than cpan, cpanm is a faster client.

    I'm trying to manually install the DBI module from CPAN ... After I downloaded the zip file in CPAN ...

    Why are you trying to do that all that manually? Strawberry Perl comes with its cpan utility which (the last time I used it) involved a command line like
        cpan install Module::DBI
    (Update: Sorry, should have checked first. Actually, at the Windows DOS command prompt, type
        c:>cpan
    to start the Strawberry cpan shell, then at the shell prompt type
        cpan> h
    for "help" info. "install" is what you're looking for.)
    to do the dirty work.

    When I typed in C:>cpan Module::DBI ... "Warning: Cannot install Module::DBI, don't know what it is"

    I don't see any Module::DBI module on CPAN (actually MetaCPAN now); are you sure this is really the name of the module?

      Thank you for your answer

      I downloaded cpanm and extracted it to the C directory

      Then, I typed in "C:\>cpanm install DBI" on the command prompt

      It somewhat worked. The module was being installed, up until an error showed up. It tells me to see a build log on the .cpanm directory.

      Upon finding the build log, I scrolled all the way down to find this error:
      "dmake.exe: Error code 129, while making 'Perl.o'"
      It is the same error I get if I install it using the cpan utility that the user AnomalousMonk suggested..

      Strangely, there is a line after I failed to install the module:
      "1 distribution installed"


      What should I do now?

        You shouldn't have to download cpanm. DWIM perl is a distro based on Strawberry (while old it should already have cpanm). Do you have multiple perl installations on your machine?

        Update:Also, DWIM perl seems down. reported, very quickly fixed by SZABGAB

        Please show other (10 or so) lines before dmake.exe: Error code 129, while making 'Perl.o' to provide more context.

    Use the string of DBI, not Module::DBI, if you want to install DBI module.
