Biber previously working now raises this error

dyld[29525]: Library not loaded: /opt/local/lib/perl5/5.20/darwin-thread-multi-2level/CORE/libperl.dylib
  Referenced from: /private/var/folders/wp/v5wwzf1j1cn10m3b5d3rf3rc0000gn/T/par-6461766964656c656761636369/cache-6bef3f811cde577dd70e44f9f5046ebc66712c46/biber
  Reason: tried: '/opt/local/lib/perl5/5.20/darwin-thread-multi-2level/CORE/libperl.dylib' (no such file), '/usr/local/lib/libperl.dylib' (no such file), '/usr/lib/libperl.dylib' (no such file)

after updating to MacOS Monterey. The closest I could find around is this discussion on github. I tried to reinstall biber & biblatex manually following the instructions how-to-upgrade-biblatex-properly, but paths do not coincide and I don't want to make a mess; and with Tex Live, but I get this error:

Unable to determine repository version

You have TeX Live 2015 installed, but the version at ftp://ftp.tug.org/historic/systems/texlive/2015/tlnet-final/ cannot be determined.

I tried also to update Tex Live as described in texlive/quickinstall by perl install-tl, which did not work either.

I am now trying to follow the instructions in updating-biblatex, but any suggestion is much appreciated.

  • That is a pretty ancient TeX Live. How was it installed; e.g., via MacTeX, Fink, etc? Please update your installation to teX Live 2021. This may be done via the MacTeX installer if you're using macOS 10.14 or later or dong a manual install. Please go to https://www.tug.org/mactex/ for information about either method (the second method is under the Unix Download link). – Herb Schulz Oct 28 '21 at 20:08
  • I did install Tex Live 2021 and this solved the problem. – DavideL Oct 28 '21 at 21:53
