Also missing in that combination

basemap                   1.2.2            py39h523bb60_3    conda-forge

matplotlib                3.3.2            py39hde42818_1    conda-forge

‌

[Reimar Bauer]

looked into basemap code

‌

‌

try:
    from inspect import cleandoc as dedent
except ImportError:
    # Deprecated as of version 3.1. Not quite the same
    # as textwrap.dedent.
    from matplotlib.cbook import dedent

‌

trying with installing typing_inspect

Part of the solution

https://github.com/conda-forge/basemap-feedstock/issues/71

Looking now at for the same reason on

from .proj import Proj

this will likly need a PR and a new build

[Reimar Bauer]

this is in basemap-1.2.2-3 solved.

[Reimar Bauer]

We get
basemap 1.2.1 py37hd1be537_2 conda-forge

but seem not to be able to update

mamba install basemap=1.2.2=py37h79d9017_3
Problem: package basemap-1.2.2-py37h79d9017_3 requires proj >=7.2.0,<7.2.1.0a0, but none of the providers can be installed

‌

[Reimar Bauer]

a clean build environment solves this
