Building a pipenv

Alternative 1: Incremental

Initialize

First, create a new and empty pipenv. If there is no Pipfile, the following command will create an empty one:

pipenv install

This will install a virtual env at a shared location on the machine, e. g. /Users/mo/.local/share/virtualenvs.

Next, install relvant packages either using CLI installs or by editing the Pipfile and doing CLI updates.

Alternative 1: CLI installs:

pipenv install flask

This automatically updates the Pipfile so that the virtual env is in sync with the Pipfile and so that installs can be reproduced on other machines.

Alternative 2: Pipfile edits and CLI updates:

Insert flask = "*" into the packages section of

pipenv update

This will also sync the Pipfile and the virtual env.

Alternative 2: Big Bang

Put your Pipfile into the working directory and run

pipenv install

Activate env

Execute

pipenv shell

from the working dir to activate the environment.
