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

**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
------------

::

$ 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.*

**Justin Myles Holmes**—
*Pipenv is finally an abstraction meant to engage the mind instead of merely the filesystem.*

**Isaac Sanders**—
*Pipenv is literally the best thing about my day today. Thanks, Kenneth!*



☤ 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

--where Output project home information.
--venv Output virtualenv information.
--py Output Python interpreter information.
--envs Output Environment Variable options.
--rm Remove the virtualenv.
--bare Minimal output.

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:
$ pipenv graph

Check your installed dependencies for security vulnerabilities:
$ pipenv check

Install a local setup.py into your virtual environment/Pipfile:
$ pipenv install -e .

Use a lower-level pip command:
$ pipenv run pip freeze

Commands:
check Checks for security vulnerabilities and against PEP 508 markers
provided in Pipfile.
clean Uninstalls all packages not specified in Pipfile.lock.
graph Displays currently–installed dependency graph information.
install Installs provided packages and adds them to Pipfile, or (if none
is given), installs all packages.
lock Generates Pipfile.lock.
open View a given module in your editor.
run Spawns a command installed into the virtualenv.
shell Spawns a shell within the virtualenv.
sync Installs all packages specified in Pipfile.lock.
uninstall Un-installs a provided package and removes it from Pipfile.




Locate the project::

$ pipenv --where
/Users/kennethreitz/Library/Mobile Documents/com~apple~CloudDocs/repos/kr/pipenv/test

Locate the virtualenv::

$ pipenv --venv
/Users/kennethreitz/.local/share/virtualenvs/test-Skyy4vre

Locate the Python interpreter::

$ pipenv --py
/Users/kennethreitz/.local/share/virtualenvs/test-Skyy4vre/bin/python

Install packages::

$ pipenv install
Creating a virtualenv for this project...
...
No package provided, installing all dependencies.

To activate this project's virtualenv, run the following:
$ pipenv shell

Install a dev dependency::

$ pipenv install pytest --dev
