Spyder: Spyder 4.2.1 - erroneous missing rtree dependency

[pythonic2020]

I just installed spyder 4.2.1 (conda-forge) into a conda environment running Python 3.7.9. When I start spyder, a window pops up and states that a dependency is missing, namely rtree >=0.8.3.

However, rtree 0.9.5 is installed.

# Name                    Version                   Build  Channel
rtree                     0.9.5            py37h13cc57e_0    conda-forge

Removing/reinstalling rtree and spyder doesn't stop the warning. Is this a bug, or is there something wrong with my environment?

Hi @pythonic2020,

Can you please create a new environment and install spyder 4.2.1 and see if the error happens in a clean environment?

conda create -n test-env python=3.7.9
conda activate test-env
conda install spyder=4.2.1

@steff456, 4.2.1 is still not available in the defaults channel, so this could be an issue with conda-forge.

Hi @steff456 ,

I got the same issue after creating a test env thus:

conda create -n test-env python=3.7.9
conda activate test-env
conda install spyder=4.2.1 -c conda-forge
