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

问题

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

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

    ----------------------------------------
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)
