Cannot install pyrosm

I’ve been trying to install this pyrosm on Windows10 and Python 3.6 because it looks potentially useful (although inadequately documented… like, which elements are included in the “walking” network?) for isolating parts of OSM data within a polygon before converting the remaining “highways” into a NetworkX graph.

However, I tried to use pip installl pyrosm, but I cannot install the package because I get the infamous “A GDAL API version must be specified” error.

` Collecting fiona Using cached Fiona-1.8.17.tar.gz (1.3 MB) ERROR: Command errored out with exit status 1: command: ‘c:\winpython\python-3.6.5.amd64\python.exe’ -c 'import sys, setuptools, tokenize; sys.argv[0] = … Complete output (1 lines): A GDAL API version must be specified. Provide a path to gdal-config using a GDAL_CONFIG environment variable or use a GDAL_VERSION environment variable.

ERROR: Command errored out with exit status 1: python setup.py egg_info Check the logs for full command output.`

The thing is, I already have the newest version of GDAL and Fiona 1.8.17 installed, and I already added GDAL to my path variables, and I can already use geopandas, fiona, shapely, rtree, etc. normally.

I couldn’t find a list of requirements and/or dependencies in the documentation aside from Py3.6, so maybe the real problem is something else.

I hope to be able to use this package, and so I appreciate any assistance in properly installing it.

@HTenkanen Thank you for incorporating this fix in the next version.

If I could go back, then I’d go the Anaconda route, as I’ve advised new people in the lab to do. But from where I am, it’s probably a few days of package version compatibility frustration just to get back to exactly where I am. Actually, if there is a function in conda to read a requirements file and get all those versions of all those packages, then it may not be so bad. I’ll look into it. But anyway, as you said, being to install via pip in Windows will only strengthen the package and broaden/accelerate its use.

@bramson Excellent, now everything seems to work. 👍 The warning that you get actually comes from geopandas (used under the hood in pyrosm). It is nothing dangerous and you can ignore it. Will add a note about this to the documentation as well.

Technical details but: It just warns that in couple of different libraries that are used under the hood of geopandas are using different version of GEOS library. This is something that will eventually be fixed once Shapely library is updated to version 2.0 (should happen sometime next year hopefully).
