"You must have heard this before"

Re: CPAN 2.29 stuck with Net::SSLeay, Re: Using Cartons to automate module installs among others.

Yeah, but it goes in one eye and out the other until I actually have a Mac. Here's output from the above scripts:

/System/Library/Perl/5.30/AnyDBM_File.pm
    AnyDBM_File.pm
access age in days: 30.07
/System/Library/Perl/5.30/sigtrap.pm
    sigtrap.pm
access age in days: 30.07
/System/Library/Perl/5.30/SelectSaver.pm

I was fine with perl being 5.30, and the truth of the matter is that I do not know the perl command to update itself. I'm left to surmise that it's implementation-dependent. hippo polled the question: why don't you have the latest perl, and my answer was that I have to change architecture to change perl. I get the system up to snuff by getting the perl up to snuff first, so that I can understand where the hell am I on a new box, real or virtual. It is clear that a lot of OS X's architecture looks like this rather than being contained places typical for linux.

I'm trying another thesis here, namely homebrew, and I see a possible conflict with layering perlbrew. I'm hoping that I have it on "set and forget."

I was ready to make this change back. Things have gotten better for me as a whole system since I bit the bullet and got a trackpad. So I'm not jones'ing for a right-click anymore. I've even done my first iMovie. Yes, part of the reason I want to be able to do all of this is to be able to make a TikTok video. Phones are too small for me, and I wanted to match architecture for the phone, where I have again rejoined the apple-verse to flee google and android. (Out of the frying pan, into the fire....)

I don't think I've got the install right until I can get cpanm, though, and I seem to be stuck:

(CPAN::Version........v5.5003)

Warning: Cannot install cpanm, don't know what it is.
Try the command

What's the deal? Is cpanm a bad idea for Macs, or am I missing something obvious to the more-experienced?

Cheers,

G'day Aldebaran,

"... I do not know the perl command to update itself."

Having been advised against using the system Perl on Mac, you wouldn't be doing this even if Perl had such a command. Correct?

I used Perlbrew on Mac for about nine years and never had any problems. I changed to Cygwin on Win10 about five years ago; still using Perlbrew and still having no problems.

Following links from Perlbrew, you'll eventually get to CPAN: perlbrew. Here you'll find documentation for perlbrew commands; in the context of the current discussion, the most pertinent are probably install, upgrade-perl, and install-cpanm.

Once you have Perlbrew installed, you can easily switch between whatever versions of Perl you have; e.g.

$ perl -v | head -2 | tail -1
This is perl 5, version 36, subversion 0 (v5.36.0) built for cygwin-th
+read-multi

$ perlbrew switch perl-5.32.0

$ perl -v | head -2 | tail -1
This is perl 5, version 32, subversion 0 (v5.32.0) built for cygwin-th
+read-multi

$ perlbrew switch perl-5.36.0

$ perl -v | head -2 | tail -1
This is perl 5, version 36, subversion 0 (v5.36.0) built for cygwin-th
+read-multi
[download]

I recommend using the following shebang in your scripts.

#!/usr/bin/env perl
[download]

This means that the script will use whatever Perl version is current.

$ cat test_shebang.pl
#!/usr/bin/env perl

print $^V;

$ ./test_shebang.pl
v5.36.0

$ perlbrew switch perl-5.33.5

$ perl -v | head -2 | tail -1
This is perl 5, version 33, subversion 5 (v5.33.5) built for cygwin-th
+read-multi

$ ./test_shebang.pl
v5.33.5

I recommend using the following shebang in your scripts.

I wish I had seen your reply before I reposted.

#!/usr/bin/env perl

fixed me entirely, thanks...I'll take another look at perlbrew, but I honestly have to pick my battles. It's all going much slower than I wanted, but I'm finally getting something like a toolchain started. Good to know that it can be done without conflict.

The way forward always starts with a minimal test.

Ok, well I though I was going along pretty well:

mymac@Merrills-Mac-mini ~ % curl -L https://cpanmin.us | perl - App::c
+panminus

Then I got to bliako's suggestion:

mymac@Merrills-Mac-mini Documents % brew analytics off

Then I start to get cpanm cranking away:

Whoa, wipeout. Ideas?

I wonder if the shebang needs changed from this particular script:

#!/usr/bin/perl -w
use 5.011;
use lib "template_stuff";
use HTML1;
use Path::Tiny;
use utf8;
use Encode;
use open OUT => ':encoding(UTF-8)', ':std';
