How to use Pipenv

Have you noticed that recommendation for Managing Application Dependency at python.org has been changed? Apparently our python community should use now Pipenv. But how to? Let's check out!

S0-E25/E30 :)

Pipenv

The Pipenv has been created by Kenneth Reitz - who complained at his blog in this post - A better pip workflow - about pip workflow - and then created this tool.

You can check Readme for pypenv at their github repository to find out what problems it solves :) I encourage you to do that !

Let's get started!

Installing Pipenv

So first things first - What do we need for Pipenv ?

  • pip - you can find out how to get pip here - but for most of the *nix users - you should already have pip packaged with your system.

Then:

pip install pipenv

Adding a shell-completion!

Bash

Put command below into your .bashrc or .bash_profile:

eval "$(pipenv --completion)"

Basic usage

Let's make some day-to-day tasks with pipenv:

Create new project using python3.6

First let's make a project with :

mkdir pipenv_test_project
cd pipenv_test_project
git init .
git commit --allow-empty -m "Init"
git remote add origin git@github.com:anselmos/pipenv_test_project.git
git push origin HEAD:master

Initialize pipenv at project

And now initialize pipenv at the pipenv_test_project:

pipenv --python 3.6

Activating pipenv at project

pipenv shell

REMEMBER - you need to be in the root path of the project.

Install all dependences including dev:

pipenv install --dev

This will create a Pipfile.lock.

Let's install some dependency i.e. selenium

pipenv install selenium

And your Pipfile and Pipfile.lock has been changed.

Installing old version of pelican and upgrading

pipenv install pelican==3.6.0

Upgrading to latest version of pelican

pipenv install pelican

Which will automatically check version and install the latest - 3.7.1 ! Yeah.

Uninstalling pelican

pipenv uninstall pelican

The pipenv_test_project

The project for this article is available here.

That was an introduction to pipenv - if you need a more advanced stuff - check documentation or pipenv --man
