Re: [ferret_users] issues installing pyferret on MacOS

[William Kessler - NOAA Federal <william.s.kessler@xxxxxxxx>]

Hi Andy -

Regarding the problem with python 3.9, see a message I sent to the group on 25 Oct 2021 "Solving the Mac/FRAME problem for PyFerret: use 7.5"

The main issue of that message was the problem of FRAME extracting only the upper-left corner of a plot in PF7.6.n, while PF7.5 worked correctly. That is still the case as far as I know (but maybe I don't know).

But it turns out that PF7.5 requires python below 3.9. Here's the error messages quoted in my 2021 email:

 

> conda install -c conda-forge pyferret==7.5.0     ! in my regular python 3.9 environment as used for 7.63

... various checking info...

First some constructive feedback. There needs to be a cleaner way to direct users to the pyferret installation instructions.  ferret.pmel.noaa.gov/Ferret/downloads/ferret-mac-os-x-downloads directs people to https://github.com/NOAA-PMEL/Ferret/releases where there is no current MacOS release, and mention of pyferret only in older releases. Please, pyferret via miniconda needs to be front-and-center as to the suggested way to install ferret, at least on MacOS and probably other platforms.

Second, I have encountered the bug? incompatibility? listed at https://github.com/conda-forge/pyferret-feedstock/issues/94. There is no obvious resolution to this issue, from the perspective of someone who uses conda for the sole purpose of getting at ferret...i.e., I am neither a conda nor a python expert and I don't know how to proceed. Somehow downgrade the python used by conda? Completely at a loss there.

Thanks for any help in advance, sorry for my grumpiness.

-Andy
