Answer 1

You may try to reset the environment variable DYLD_FALLBACK_LIBRARY_PATH:

export DYLD_FALLBACK_LIBRARY_PATH=$(HOME)/lib:/usr/local/lib:/lib:/usr/lib

Answer 2

@user2977865 and @anothernode are correct in their approach but it may not work for everyone. By default, shapely will look for libraries in the DYLD_PATH.

I had it set to DYLD_LIBRARY_PATH=/usr/local/lib/:/usr/local/mysql/lib/

But these libraries are placed in /usr/lib.

So I had to modify it as follows:

export DYLD_LIBRARY_PATH=/usr/lib/:/usr/local/mysql/lib/

Bonus note: Ensure that your environment variables have been set by restarting terminal and clearing cache of any IDEs you might be using.

Answer 3

The way I fixed it:

apk add geos libc-dev musl-dev
pip install Shapely

Answer 4

For me, only works after installing Shapely from the shapely lib and executing the following command from Anaconda Prompt:

pip install Shapely-1.7.1-cp37-cp37m-win_amd64.whl --force-reinstall

This forces a re-install of shapely.

Answer 5

I simply uninstalled Shapely and re-installed it to fix the issue.

python -m pip uninstall shapely

python -m pip install shapely
