---------------

**Pipenv** — the officially recommended Python packaging tool from `Python.org <https://packaging.python.org/tutorials/managing-dependencies/#managing-dependencies>`_, free (as in freedom).

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.

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 <https://www.kennethreitz.org/essays/a-better-pip-workflow>`_, so Pipenv uses the upcoming ``Pipfile`` and ``Pipfile.lock`` instead, which is superior for basic use cases.
- Hashes are used everywhere, always. Security. Automatically expose security vulnerabilities.
- Give you insight into your dependency graph (e.g. ``$ pipenv graph``).
- Streamline development workflow by loading ``.env`` files.

Installation
------------

If you're on MacOS, you can install Pipenv easily with Homebrew::

    $ brew install pipenv

Or, if you're using Ubuntu 17.10::

    $ sudo apt install software-properties-common python-software-properties
    $ sudo add-apt-repository ppa:pypa/ppa
    $ sudo apt update
    $ sudo apt install pipenv

Otherwise, just use pip::

    $ pip install pipenv

☤ User Testimonials
-------------------

**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.*


☤ 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
//////////////

- ``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``).
- ``check`` asserts that PEP 508 requirements are being met by the current environment.
- ``graph`` will print a pretty graph of all your installed dependencies.

Shell Completion
////////////////

For example, with fish, put this in your ``~/.config/fish/completions/pipenv.fish``::

    eval (pipenv --completion)

Alternatively, with bash, put this in your ``.bashrc`` or ``.bash_profile``::

    eval "$(pipenv --completion)"

Magic shell completions are now enabled! There is also a `fish plugin <https://github.com/fisherman/pipenv>`_, which will automatically activate your subshells for you!

Fish is the best shell. You should use it.

☤ Usage
-------

::

    $ pipenv
    Usage: pipenv [OPTIONS] COMMAND [ARGS]...

    Usage Examples:
       Create a new project using Python 3.6, specifically:
       $ pipenv --python 3.6

       Install all dependencies for a project (including dev):
       $ pipenv install --dev

       Create a lockfile containing pre-releases:
       $ pipenv lock --pre

       Show a graph of your installed dependencies:
