pip3 installs inside virtual environment with python3.6 failing due to ssl module not available

by

I followed the below steps for python3.6 installation in ubuntu 14.04 and virtualenv pip installs works fine.

Python 3.6 Installation:

sudo apt-get install python3-dev libffi-dev libssl-dev
wget https://www.python.org/ftp/python/3.6.0/Python-3.6.0.tgz  
tar xvf Python-3.6.0.tgz
cd Python-3.6.0
./configure --enable-optimizations  
make -j8  
sudo make altinstall
python3.6

If seeing the following error —

zipimport.ZipImportError: can’t decompress data; zlib not available
make: *** [altinstall] Error 1

try:

sudo apt-get install zlib1g-dev

Validation:

Create virtualenv in python3.6:

python3.6 -m venv testenv
source testenv/bin/activate
pip install pep8

using pip:

(testenv) vagrant@pvagrant-dev-vm:~$ pip install pep8
