Package: pipenv-cn
Pipenv: Python Development Workflow for HumansPipenvis 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 yourPipfileas you
install/uninstall packages. It also generates the ever-importantPipfile.lock, which is used to produce deterministic builds.The problems that Pipenv seeks to solve are multi-faceted:You no longer need to usepipandvirtualenvseparately. They
work together.Managing arequirements.txtfilecan be
problematic,
so Pipenv uses the upcomingPipfileandPipfile.lockinstead,
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.envfiles.You can quickly play with Pipenv right in your browser:InstallationIf you're on MacOS, you can install Pipenv easily with Homebrew:$ brew install pipenvOr, if you're using Debian Buster+:$ sudo apt install pipenvOr, if you're using Fedora:$ sudo dnf install pipenvOr, if you're using FreeBSD:# pkg install py36-pipenvOtherwise, refer to thedocumentationfor instructions.✨🍰✨☤ User TestimonialsDavid 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.☤ FeaturesEnables trulydeterministic builds, while easily specifyingonly
what you want.Generates and checks file hashes for locked dependencies.Automatically install required Pythons, ifpyenvis available.Automatically finds your project home, recursively, by looking for aPipfile.Automatically generates aPipfile, if one doesn't exist.Automatically creates a virtualenv in a standard location.Automatically adds/removes packages to aPipfilewhen they are
un/installed.Automatically loads.envfiles, if they exist.The main commands areinstall,uninstall, andlock, which
generates aPipfile.lock. These are intended to replace$ pip installusage, as well as manual virtualenv management (to
activate a virtualenv, run$ pipenv shell).Basic ConceptsA virtualenv will automatically be created, when one doesn't exist.When no parameters are passed toinstall, 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 Commandsshellwill spawn a shell with the virtualenv activated.runwill run a given command from the virtualenv, with any
arguments forwarded (e.g.$ pipenv run python).checkasserts that PEP 508 requirements are being met by the
current environment.graphwill print a pretty graph of all your installed
dependencies.Shell CompletionFor example, with fish, put this in your~/.config/fish/completions/pipenv.fish:eval (pipenv --completion)Alternatively, with bash, put this in your.bashrcor.bash_profile:eval "$(pipenv --completion)"Magic shell completions are now enabled! There is also afish
plugin, which will automatically
activate your subshells for you!Fish is the best shell. You should use it.☤ Usage$ pipenv
Usage: pipenv [OPTIONS] COMMAND [ARGS]...

Options:
  --where          Output project home information.
  --venv           Output virtualenv information.
  --py             Output Python interpreter information.
  --envs           Output Environment Variable options.
  --rm             Remove the virtualenv.
  --bare           Minimal output.
  --completion     Output completion (to be eval'd).
  --man            Display manpage.
  --three / --two  Use Python 3/2 when creating virtualenv.
  --python TEXT    Specify which version of Python virtualenv should use.
  --site-packages  Enable site-packages for the virtualenv.
  --version        Show the version and exit.
  -h, --help       Show this message and exit.


Usage Examples:
   Create a new project using Python 3.7, specifically:
   $ pipenv --python 3.7

   Remove project virtualenv (inferred from current directory):
   $ pipenv --rm

   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 no
             packages are given), installs all packages from Pipfile.
  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

To activate this project's virtualenv, run the following:
$ pipenv shellInstalling from git:You can install packages with pipenv from git and other version control systems using URLs formatted according to the following rule:<vcs_type>+<scheme>://<location>/<user_or_organization>/<repository>@<branch_or_tag>#<package_name>The only optional section is the@<branch_or_tag>section.  When using git over SSH, you may use the shorthand vcs and scheme aliasgit+git@<location>:<user_or_organization>/<repository>@<branch_or_tag>#<package_name>. Note that this is translated togit+ssh://git@<location>when parsed.Valid values for<vcs_type>includegit,bzr,svn, andhg.  Valid values for<scheme>includehttp,,https,ssh, andfile.  In specific cases you also have access to other schemes:svnmay be combined withsvnas a scheme, andbzrcan be combined withsftpandlp.Note that it isstrongly recommendedthat you install any version-controlled dependencies in editable mode, usingpipenv install -e, in order to ensure that dependency resolution can be performed with an up to date copy of the repository each time it is performed, and that it includes all known dependencies.Below is an example usage which installs the git repository located athttps://github.com/requests/requests.gitfrom tagv2.19.1as package namerequests:$ pipenv install -e git+https://github.com/requests/requests.git@v2.19#egg=requests
