问题
I try to install the module contextily to use it on Python.
I went on Anaconda Prompt as admin, and wrote : pip install contextily
I get this error and I have still not found what I have to do :
Getting requirements to build wheel ... error
ERROR: Command errored out with exit status 1:

Complete output (2 lines):

(I tried to deal with environment variable like there : No module named ogr but it doesn't help. Neither these solutions : Error installing geopandas:" A GDAL API version must be specified " in Anaconda)
回答1:
I achieved to install packages that I couldn't before, by creating a virtual environment and working on it (it's simple on Anaconda Navigator : Environments/Create, and then using the right part of the navigator to install new packages)

As a python beginner I ran in the same error but https://anaconda.org/conda-forge/contextily and conda install -c conda-forge contextily worked for me.
