Some of odoo dependencies are non-pure Python packages which requires C/C++ compilation during their installation process. you can install those dependencies using one of the following approaches.

1. Download and install already compiled dependencies in Wheel (.whl) format targeting your system configuration.
2. Download and install C/C++ compiler than install those dependencies from source.

For installing dependencies from Wheel (.whl), launch Command Prompt as Administrator.

• Install pypiwin32 by > python3 -m pip install pypiwin32
• Install Pillow by > python3 -m pip install Pillow-3.4.2-cp36-cp36m-win_amd64.whl
• Install gevent by > python3 -m pip install gevent-1.2.2-cp36-cp36m-win_amd64.whl

If you're having 32 bit Windows architecture or other Python versions (e.g. 3.4, 3.5) installed on your system. you can download non-pure Python package Wheels (.whl) targeting your system configurations from PyPI or Laboratory for Fluorescence Dynamics. If you're having Python 3.4 installed on system then you will require Microsoft Visual C++ 2010 Redistributable instead of Microsoft Visual C++ 2015 Redistributable. for more information visit WindowsCompilers article on Python Wiki.

For installing dependencies from source, download Visual C++ 2015 Build Tools.

• run the installer,
• select custom mode for installation,
• uncheck all optional features (e.g. Windows 8.1 SDK, Windows 10 SDK, ATL/MFC SDK, .NET Framework SDK etc.)
• click Install.
  

After Visual C++ 2015 Build Tools installation process completes, launch Command Prompt as Administrator

• Install pypiwin32 by > python3 -m pip install pypiwin32
• Install Pillow by > python3 -m pip install pillow
• Install gevent by > python3 -m pip install gevent
• Install lxml by > python3 -m pip install lxml
• Install psutil by > python3 -m pip install psutil
• Install psycopg2 by > python3 -m pip install psycopg2
• Install pyldap by > python3 -m pip install pyldap
• Install reportlab by > python3 -m pip install reportlab

If you're having Python 3.4 installed on system then you will require Microsoft Windows SDK for Windows 7 and .NET Framework 4 instead of Visual C++ 2015 Build Tools. for more information visit WindowsCompilers article on Python Wiki.
