I've upgraded setuptools , wheel but it did not work.
what else should I try ?

As it says on the PyPI page of the package:

Quote:Windows users have two good installation options: the wheels at http://www.lfd.uci.edu/~gohlke/pythonlibs/#shapely and the Anaconda platform’s [conda-forge](https://conda-forge.github.io/) channel.

So, download the correct wheel for your system from Gohlke and use it to install the package

Assuming you have 64-bit version of Python 3.4 installed
1. download Shapely‑1.6.4.post1‑cp34‑cp34m‑win_amd64.whl
2. use pip install Shapely‑1.6.4.post1‑cp34‑cp34m‑win_amd64.whl assuming you are in the same folder where the downloaded wheel is
