G'day programmingzeal,

If you SuperSearch for "ChatGPT" here, you'll find that it's mostly been lacking, in one way or another, with respect to Perl queries. In this instance, it's found Perl6, and presumably assumed that's an upgrade from Perl5: that's not the case — Perl6 is considered a sister language to Perl5; I don't imagine Perl6 is what you want. Perl6 was renamed to Raku some years ago; the Raku FAQ has more about that.

Perl v5.32.1 is the latest, stable release from Strawberry Perl; it's what you currently have. There are later, experimental versions: probably not what you want; there's further discussion in "When might we see new releases of Strawberry Perl on Windows".

There was a similar (Jupyter) question some weeks ago: "jupyter kernel perl". This didn't lead to a solution; the last post in that thread has "no luck so far"; it's also for a different OS. However, there may be some useful information there; perhaps leading to further avenues for investigation.

I am on my personal laptop with no proxy settings. I am using wi-fi and cellular internet without proxy settings. But let me check jupyter network settings.

Jupyter notebook runs in my chrome browser and there are no proxy settings. I have enabled windows 10 original firewall. First I thought that the above error is due to the fact that jupyter is not running and installing Devel::IPerl might be requiring jupyter notebook instance running but this even has not resolved the issue. I decided to run cpan commands in jupyter notebook terminal tab in my chrome browser. Now I am using browser jupyter terminal tab for cpan commands. I again looked at the dependencies errors and found that for installing Devel::IPerl following dependencies are unmet.


Warning: prerequisite IO::Async::Handle 0 not found.
Warning: prerequisite IO::Async::Loop 0 not found.
Warning: prerequisite IO::Async::Routine 0 not found.
Warning: prerequisite Net::Async::ZMQ 0.002 not found.
Warning: prerequisite Net::Async::ZMQ::Socket 0 not found.
Warning: prerequisite ZMQ::FFI 1.18 not found.

I tried resolving/installing one by one from top to bottom but every dependency required additional dependency or failed tests all with HTTP / connection /webserver sort of test fail errors. In last I tried installing ZMQ::FFI but it failed with following dependencies:


Unsatisfied dependencies detected during ----
----       MLEHMANN/AnyEvent-7.17.tar.gz      ----
    Async::Interrupt [requires,optional]
    EV [requires,optional]
    Guard [requires,optional]

I then individually resolved all the above three dependencies installations and upon running "install AnyEvent" it generated following error where notable error is about test unable to make connection with host machine / network configuration error / environment variable setting etc.

So I believe the test failing is during some dependency installation which is unable to make connection with host machine. The error of Future:IO is at following .pm file line 194:

C:\STRAWB~1\cpan\build\Future-IO-0.13-5\blib\lib/Test/Future/IO/Impl.pm



The code of .pm file is as follows:

Future::IO->connect failure

Edit

There was a talk about Perl & Jupyter at the German PW 2020

But I don't remember much, I doubt it was for windows.

I've messaged the presenter a link to this thread though, he might show up.

Yes I tried following command but it is stopping at above error:
 cpan> install Devel::IPerl
I even treid following but no good:

cpan> upgrade Devel::IPerl
All modules are up to date for Devel::IPerl
[download]

Johann, the presenter messaged me back that it's most likely because there is a dependency to ZeroMQ which is missing in the distribution's config.

There are also no tests for Win in the testers matrix.

http://matrix.cpantesters.org/?dist=Devel-IPerl+0.012

So it's unclear if it works there.

I deleted the post on stack overflow. It means cross posting on different forums is forbidden. I never knew. Thanks.

Hello programmingzeal,

No, it’s not forbidden, and there’s no need to delete a cross-post. It’s simply considered polite to let the monks know that a query is cross-posted, so they don’t waste time addressing a question which has already been answered elsewhere. LanX was just giving other monks a heads-up.

Cheers,

Athanasius <°(((>< contra mundum

סתם עוד האקר של פרל,

It means cross posting on different forums is forbidden

Not forbidden, just customary to let us know.

It's impolite. At least not to tell.

When asking for help you don't waste the energy of the helpful.

I personally only switch forums for the same questions after some days of unfruitful waiting and not without linking back for reference to the results already achieved.

Cheers Rolf
