I ran into the problem that some people seem to have with Demeter on mac while upgrading to High Sierra. I found a fix on this mail list, but…
1) I can’t download Template.pm from the archive (bin file that uncompresses to cpgz file that uncompresses back to a bin file…)
2) Matt mentions that he installed 0.9.26 from macports, but I see only 0.9.25 (stable & develop).
Sorry for the trivial questions :-)
All the best, JOEL

[Ifeffit] install for mac error

Hi All,

I see this error too. This is a bit of a bodge job, but if you replace:

/opt/local/lib/perl5/vendor_perl/5.26/Text/Template.pm

With the attached template.pm from p5.24, it seems to work fine. I’d just rename the old Template.pm in the same directory, rather than deleting it – since another program may end up needing the most recent one.

Cheers,

Luke

Thank you for the input Matt. I am glad to hear that it is not “user error”. I tried it again and I need to correct my earlier statement because Artemis GUI will stay open after the warning however Athena closes/crashes.
I will try on a different system.

Thanks again,

Chris

Hello everyone,

I tried to install demeter on my mac (running high Sierra) and it appeared everything went well.  However when I run either Athena or Artemis I get an error shown below about Demeter::Templates: showing a error and I am not sure how I can correct this error.  Any help would be appreciated.

Thanks in advanced,

I can confirm this.  I just did a fresh install of Macports on 10.13.3 (high sierra).  The MacPorts install was not super easy, but once it got to the demeter install, that part went fine.
I see the same problem with athena from demeter 0.9.25. I think the warnings about "Demeter::Templates::F" and so forth are meant to be warnings only -- I think they may not be related to the crash of athena.   For me, hephaestus gives the same sort of warnings, but runs fine.
I can install and run Demeter 0.9.26 (including using Larch as a backend) using Macports, though there are definitely some Mac-specific weirdness. Anyway, I do not believe that "install from source" is a feasible approach for demeter on OSX. I do not know enough about Macports to update the existing package.  I don't know that using some other system would be an improvement.

We keep seeing problems with demeter on OSX.   I'm not sure what the right answer is.  Anyone have any suggestions?
