Install Shapely: OSError: [WinError 126] The specified module could not be found

I have to install Shapely package (http://toblerity.org/shapely/project.html#installation). But when I am using:

pip install Shapely

I am getting this error:

Collecting Shapely

    Complete output from command python setup.py egg_info:

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in C:\Users\AppData\Local\Temp\pip-build-mwuxcain\Shapely\

And, when I am using:

conda install shapely

I am getting this error:

Fetching package metadata ...........


PackageNotFoundError: Package not found: Conda could not find '

I am using Python 3.6.0 (Anaconda3) on Windows 10 (64-bit).

Please help. (nothing works)

Solution 1:

Download WHL file using http://www.lfd.uci.edu/~gohlke/pythonlibs/#shapely

Install:

python -m pip install Shapely-1.5.17-cp36-cp36m-win_amd64.whl

Ubuntu:

pip install shapely==1.6b2

Solution 2:

You can also use

conda install -c conda-forge shapely

It worked for me.

Solution 3:

pip install shapely was not working but conda install shapely worked fine for me (windows user)
