Pipenv is by far the best thing to happen to python in 2017. It is so good, it is already the official recommendation for package management.

If you have a custom installation of python3 on Bluehost, these steps will be easy to follow.

        

# install pipenv using pip (locally for the user, recommended!)
pip install --user pipenv

# add pipenv to the PATH (usually in ~/.local/bin)
export PATH=~/.local/bin:${PATH}

        
    

There, you have pipenv installed on Bluehost. Now, using it is easy. This is a short summary of commonly performed actions.

        

# initiate a python3 project
pipenv --python 3.6.4

# install some package (for example, Flask)
pipenv install flask

# uninstall some package (for example, Flask-SQLAlchemy)
pipenv uninstall flask-sqlalchemy

# lock the Pipfile (to enable deployment somewhere else.)
pipenv lock

# start a pipenv shell to run with the python packages local to this project
pipenv shell

        
    

Now that you have a working website on your local machine, maybe you wish to deploy it on the server. Easy-peasy. Just make the Pipfile and Pipfile.lock part of your git and make it available on the web-server. Then to instantiate your project on the webserver, do the following steps.

        

# in the project directory with the Pipfile present. 
pipenv install

        
    

There, your project is ready to be served. Check out my article on (serve-flask-on-bluehost-using-mod-fcgi-with-pipenv)[serving Flask webpages using mod_fcgi on Bluehost with a pipenv configuration], if you intend to do so next.
