问题
Hello I am trying to install OSMnx and GeoPandas using pip install osmnx and pip install geopandas (according to this link: https://geoffboeing.com/2016/11/osmnx-python-street-networks/) It says that in order to use OSMnx you have to install geopandas and rtree first, rtree was installed with no issues, but this happened when trying to install osmnx (actually I tried to install osmnx before I found out that I need to install geopandas, I am giving this error here in order to give you as much information as possible)

What shall I do (I do NOT want to install anaconda, so if there is a way of avoiding anaconda I would be very happy)?
Any help appreciated, thank you very much
EDIT: OK I tried the steps explained in the question mentioned as a duplicate of my question, I was able to install fiona following these steps but when I typed pip install geopandas I got this new error:

EDIT 2: Even though the cmd wrote "succesfully installed fiona" when I tried to run simple Attempt.py
import fiona
I got this message:

This may also help with troubleshooting of my issue
回答1:
It can be really difficult to install the geospatial dependencies with pip, primarily due to Fiona in my experience. If you can use conda, it's strongly recommended to follow the install instructions in the OSMnx documentation
If you have any trouble with the installation, try installing OSMnx in a new, clean conda environment using conda-forge and strict channel priority:
conda config --prepend channels conda-forge
conda create -n ox --strict-channel-priority python=3 osmnx
