Answer
At its simplest, the problem here is there is no build of cartopy available on anaconda cloud that meets the combination of linux-32
and py35
. There are some linux-32
builds available (from Unidata and pelson, for example) and some py35
builds (from IOOS, for example), but none that do both.
This is because…
py35
is reasonably new, so there are relatively few people building against it at the moment, andlinux-32
is now reasonably old, so few people still build packages for it.
The easiest solution is to change one of your dependencies. For example, if you can change your Python requirement to py34
then you can use the Unidata linux-32
build of cartopy. Note that this is an older build of cartopy, however, at v0.13.0 compared to the latest release of v0.14.3.
If you want a challenge another solution to this would be to build cartopy for yourself! The recipe (what the final cartopy version is built from) can be found in a GitHub organisation called conda-forge (at https://github.com/conda-forge/cartopy-feedstock). There are some instructions on updating a recipe here: https://conda-forge.github.io/#update_recipe.
