[GCC 4.8.5 20150623 (Red Hat 4.8.5-11)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import pyodbc
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named 'pyodbc'
Below is pip version
-bash-4.2$ pip3 -V

Requirement already satisfied: pyodbc==3.0.10 in

Answer 1

The issue is unrelated to PIP
fatal error: Python.h: No such file or directory
You are missing your GCC (C++/C Compiler) and Development Tools from your machine - hence the missing C header file
You can install the following YUM group to satisfy the requirement:
RedHat / CentOS:
sudo yum group install "Development Tools"
or
sudo yum groupinstall "Development Tools"
