Installation Shapely: OSError: [WinError 126] Impossible de trouver le module spécifié

Question

Je dois installer le package Shapely (http://toblerity.org/shapely/project.html#installation). Mais quand je me sers:

pip install Shapely 

Je reçois cette erreur:

Collecting Shapely 
    Using cached Shapely-1.5.17.tar.gz 
    Complete output from command python setup.py egg_info: 
    Traceback (most recent call last):

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

Et, quand je me sers:

conda install shapely 

Je reçois cette erreur:

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


PackageNotFoundError: Package not found: Conda could not find ' 

J'utilise Python 3.6.0 (Anaconda3) sur Windows 10 (64 bits).

Aidez-nous s'il vous plaît. (Rien ne fonctionne)
