Upon searching and as suggested in several posts I have updated pip and setuptools and installed shapely as well but I get same error. I am trying to install through pip and not conda. Can someone suggest how to resolve this issue and install the library.

download the rtree wheel from another website, and install rtree from that wheel. then install osmnx again. Also try to install from wheel for any other dependencies which might produce errors. — Atreyagaurav, Oct 25 '20 at 10:40
Thanks for your answer. I got it solved by installing `spatialindex` and `rtree` then `osmnx`. — mockash, Oct 25 '20 at 10:43

Below is the process I have followed to overcome this error. Try to upgrade your setuptools.

pip install --upgrade setuptools and if still facing the same issue check if all dependencies of osmnx are installed. In my case I had to do pip install rtree and this was also dependent on spatialindex which I have installed through yum install spatialindex. Then pip install osmnx which worked wonderfully.

Kindly note that spatialindex in ubuntu and debian is libspatialindex-dev.

Also one can follow instructions provided by @gboeing in his answer here.
