cpan install fails with bad tar call

[RockyRoccoco]

I just installed Strawberry perl using standard install choices. I have attempted in the "perl (command line)" window to install several required modules. I also have msys2 installed on this machine. I think there is some interference between msys2 and windows. Here is the result of trying to install a package: Install command:

 
cpan install Gedcom

Result:

I need to keep msys2 in this machine. Any thoughts on how to get perl to use the correct tar, or the correct path form?

After rereading the thread referenced by thanos1983, my question is: Do you happen to have Perl (or msys) installed somewhere under C:\Program Files (or C:\Program Files (x86))? If so, that would most probably be the cause of the problem.

Check which cpan is being called. You are probably using the version from msys2, which is why it then looks for /usr/bin/tar.

On my system:

where cpan
C:\berrybrew\5.28.0_64_PDL\perl\bin\cpan.bat

If you are running the portable shell that comes with Strawberry Perl then it should put all the strawberry paths at the front of %PATH%. Perhaps double check that you are using that shell.

And FWIW, I have MSYS2 and several versions of Strawberry perl installed on my system (via Berrybrew) and they don't interfere with each other. That said, none of them are in my default path. I only ever start MSYS2 from its menu option, and strawberry perl via a bat file that prepends the paths (similar to what its portable shell does).

Hello RockyRoccoco,

Welcome to the Monastery. You can read this previously asked question CPAN module installs failing. Possibly the solution will work on your case also.

Let us know.

I've looked at it. DIfferent OS, path referred to is not found currently, no component of the path is found. So, no. But it is possibly a good direction. I need to know where to correct tar is located on my windows 10 system. I also am trying to figure out how to separate msys2 from regular windows programs. That's probably what is going on.

In my experience, you can use whichever tar you like - but I don't think the cpan utility that ships with my my Strawberry Perls uses "tar" at all.
(I guess they use Archive::Tar.)

Looks to me that your C:\Users\Owner\.cpan\MyConfig.pm has been written for msys2's perl - not for Strawberry Perl.

That being so, the solution would be to have separate cpan home directories for Strawberry Perl and msys2's perl.

Other than that, it might be handy if you could show us a copy of your MyConfig.pm.
Please first remove any sensitive information contained therein.

Certainly something that has been written for an msys2 perl is being accessed as both "/usr/bin/tar" and "/c/Users/Owner/..." are paths that would work fine in in an msys2 shell.
However, if backslashes are substituted for forward slashes, not even msys2 will be able to make sense of them.

Cheers,
Rob
