Sacred Marriage of Pipfile, Pip, & Virtualenv.
Project description
Pipenv — the officially recommended Python packaging tool from Python.org, free (as in freedom).
Pipenv harnesses Pipfile, Pip, and Virtualenv together in unison to create a single, high-quality tool that is optimized for workflow efficiency and best practices.
Pipenv automatically creates and manages the virtualenvs of your projects, as well as adds/removes packages from your Pipfile as you install/uninstall packages. The lock command generates a lockfile (Pipfile.lock).
The problems that Pipenv seeks to solve are multi-faceted:
When using Pipenv, you no longer need to use pip and virtualenv separately. They work together.
Managing a requirements.txt file can be problematic, so Pipenv uses the upcoming Pipfile and Pipfile.lock instead, which is superior for basic use cases.
Installation
$ pip install pipenv

☤ User Testimonials
- Jannis Leidel, former pip maintainer—
Pipenv is the porcelain I always wanted built for pip. It fits my brain and mostly replaces virtualenvwrapper and manual pip calls for me. Use it.
- Jhon Crypt—
Pipenv is the best thing since pip, thank you!
- Isaac Sanders—
Pipenv is literally the best thing about my day today. Thanks, Kenneth!
☤ Features
Enables truly deterministic builds, while easily specifying what you want.
Generates and checks file hashes for locked dependencies (via --hashes).
Automatically finds your project home, recursively, by looking for a Pipfile.
Automatically generates a Pipfile, if one doesn’t exist.
Automatically generates a Pipfile.lock, if one doesn’t exist.
Automatically creates a virtualenv in a standard location.
Automatically adds packages to a Pipfile when they are installed.
Automatically removes packages from a Pipfile when they are un-installed.
Also automatically updates pip.
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.
Shell Completion
Set _PIPENV_COMPLETE and then source the output of the program. For example, with fish, put this in your ~/.config/fish/completions/pipenv.fish:
eval (env _PIPENV_COMPLETE=source-fish pipenv)
Magic shell completions are now enabled! There is also a fish plugin, which will automatically activate your subshells for you!
Fish is the best shell. You should use it.
☤ Usage
$ pipenv Usage: pipenv [OPTIONS] COMMAND [ARGS]... Options: --where Output project home information. --venv Output virtualenv information. --rm Remove the virtualenv. --bare Minimal output. --three / --two Use Python 3/2 when creating virtualenv. --python TEXT Specify which version of Python virtualenv should use. -h, --help Show this message then exit. --version Show the version and exit. Usage Examples: Create a new project using Python 3: $ pipenv --three Install all dependencies for a project (including dev): $ pipenv install --dev Create a lockfile: $ pipenv lock Commands: check Checks PEP 508 markers provided in Pipfile. install Installs provided packages and adds them to... lock Generates Pipfile.lock. run Spawns a command installed into the... shell Spawns a shell within the virtualenv. uninstall Un-installs a provided package and removes it... update Updates pip to latest version, uninstalls all...
