cpan: Terminal does not support AddHistory.by kcott (Bishop)
|on Jan 05, 2021 at 04:39 UTC||Need Help??|
I have been seeing the following, for the past 18 months, every time I use the cpan utility:
I looked into that briefly (and unsuccessfully) several times; in general, whatever I wanted to install via cpan was more important than AddHistory, which I only use infrequently anyway, so it ended up on my TODO list.
I tried with the suggested module, Term::ReadLine::Perl, as well as a variety of others including: Term::ReadLine::Perl5, Term::ReadLine::Gnu, and Term::ReadLine::Tiny. These all failed, the most common problem being the process hanging when the Term::ReadKey dependency was being installed. Actually, installation of Term::ReadLine::Tiny worked fine but it didn't provide AddHistory.
I spent some hours this morning looking into this and eventually came up with a solution. My basic Perl setup is: Win10 - Cygwin - Perlbrew - Perl 5.32.0. If you're experiencing the same problem, this solution may work for you: I can't make any guarantees as I don't have other systems on which to test this.
The only thing that worked was a completely manual installation.
Download https://cpan.metacpan.org/authors/id/J/JS/JSTOWE/TermReadKey-2.38.tar.gz then run the familiar incantation:
Download https://cpan.metacpan.org/authors/id/H/HA/HAYASHI/Term-ReadLine-Gnu-1.37.tar.gz then a very similar incantation:
Now I get:
and moving through the command history and editing is now possible.
If you were experiencing similar problems with a different setup to me — and found this worked as is, worked after some modification, or failed abysmally — please leave a note for the next reader.
