Jinja install for python
have a look at this. You can use setuptools or pip to install jinja. Just enter those command into a DOS prompt
easy_install Jinja2
or
pip install Jinja2
You should have easy_install.exe bundled with your python on windows
Hope this helps
I needed to install jinja2 as a dependency for Ansible and didn't want to use pip or pip3. Installing python-jinja2 package did the trick:
apt install python-jinja2
