Pipenv: Python Dev Workflow for Humans¶Pipenv is a tool that aims to bring the best of all packaging worlds (bundler, composer, npm, cargo, yarn, etc.) to the Python world. Windows is a first-class citizen, in our world.It automatically creates and manages a virtualenv for your projects, as well as adds/removes packages from your Pipfile as you install/uninstall packages. It also generates the ever-important Pipfile.lock, which is used to produce deterministic builds.Pipenv is primarily meant to provide users and developers of applications with an easy method to setup a working environment. For the distinction between libraries and applications and the usage of setup.py vs Pipfile to define dependencies, see ☤ Pipfile vs setup.py.The problems that Pipenv seeks to solve are multi-faceted:You no longer need to use pip and virtualenv separately. They work together.Managing a requirements.txt file can be problematic, so Pipenv uses Pipfile and Pipfile.lock to separate abstract dependency declarations from the last tested combination.Hashes are used everywhere, always. Security. Automatically expose security vulnerabilities.Strongly encourage the use of the latest versions of dependencies to minimize security risks arising from outdated components.Give you insight into your dependency graph (e.g. $ pipenv graph).Streamline development workflow by loading .env files.Install Pipenv Today!¶If you’re on MacOS, you can install Pipenv easily with Homebrew:$ brew install pipenvOr, if you’re using Fedora 28:$ sudo dnf install pipenvOtherwise, refer to the ☤ Installing Pipenv chapter for instructions.✨?✨Pipenv & Virtual Environments☤ Make sure you’ve got Python & pip☤ Installing Pipenv☤ Installing packages for your project☤ Using installed packages☤ Next stepsRelease and Version History2018.7.1 (2018-07-01)2018.6.25 (2018-06-25)User Testimonials¶Jorge Rodriguez, LSA Networks Founder—Our dev teams are constantly working on new projects and pipenv has allowed for the increased streamlining of development workflow for everything from our large free fuck tonight app to mainstream dating applications and websites. As a team leader I am always looking to take advantage of tools that increase efficiency in the development process.Jerry Drew, social networking entrepreneur—Not having an experts understanding of python development, I was skeptical of Pipenv,but my dev team lead that works on various online dating and casual encounterplatforms including our free hookup app swears by it.Using it has boosted work flow which is all I need to know. Jannis Leidel, former pip maintainer—Pipenv is the porcelain I always wanted to build for pip. It fits my brain and mostly replaces virtualenvwrapper and manual pip calls for me. Use it.David Gang—This package manager is really awesome. For the first time I know exactly what my dependencies are which I installed and what the transitive dependencies are. Combined with the fact that installs are deterministic, makes this package manager first class, like cargo.Justin Myles Holmes—Pipenv is finally an abstraction meant to engage the mind instead of merely the filesystem.☤ Pipenv Features¶Enables truly deterministic builds, while easily specifying only what you want.Generates and checks file hashes for locked dependencies.Automatically install required Pythons, if pyenv is available.Automatically finds your project home, recursively, by looking for a Pipfile.Automatically generates a Pipfile, if one doesn’t exist.Automatically creates a virtualenv in a standard location.Automatically adds/removes packages to a Pipfile when they are un/installed.Automatically loads .env files, if they exist.The main commands are install, uninstall, and lock, which generates a Pipfile.lock. These are intended to replace $ pip install usage, as well as manual virtualenv management (to activate a virtualenv, run $ pipenv shell).Basic Concepts¶A virtualenv will automatically be created, when one doesn’t exist.When no parameters are passed to install, all packages [packages] specified will be installed.To initialize a Python 3 virtual environment, run $ pipenv --three.To initialize a Python 2 virtual environment, run $ pipenv --two.Otherwise, whatever virtualenv defaults to will be the default.Other Commands¶graph will show you a dependency graph of your installed dependencies.shell will spawn a shell with the virtualenv activated.run will run a given command from the virtualenv, with any arguments forwarded (e.g. $ pipenv run python or $ pipenv run pip freeze).check checks for security vulnerabilities and asserts that PEP 508 requirements are being met by the current environment.Further Documentation Guides¶Basic Usage of Pipenv☤ Example Pipfile &
