INSTALLATION
Installation¶ Do I need to install pip?¶ pip is already installed if you are using Python 2 >=2.7.9 or Python 3 >=3.4 downloaded from python.org or if you are working in a Virtual Environment created by virtualenv or venv.Just make sure to upgrade pip.. Use the following command to check whether pip is installed: 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 VIRTUALENV — VIRTUALENV 20.4.8.DEV2+G4C6CA96 DOCUMENTATION Virtualenv¶. virtualenv is a tool to create isolated Python environments. Since Python 3.3, a subset of it has been integrated into the standard library under the venv module.The venv module does not offer all features of this library, to name just a few more prominent: is slower (by not having the app-data seed method),. is not as extendable, cannot create virtual environments for PIPENV & VIRTUAL ENVIRONMENTS Note. This does a user installation to prevent breaking any system-wide packages. If pipenv isn’t available in your shell after installation, you’ll need to add the user base’s binary directory to your PATH..

Using Environment Variables¶. Since version 10, pip supports the use of environment variables inside the requirements file. You can now store sensitive data (tokens, keys, etc.) in environment variables and only specify the variable name for your requirements, letting pip lookup the value at runtime.

Pipfile.lock takes advantage of some great new security improvements in pip.By default, the Pipfile.lock will be generated with the sha256 hashes of each downloaded package. This will allow pip to guarantee you’re installing what you intend to when on a compromised network, or downloading dependencies from an untrusted PyPI endpoint.PIP DOWNLOAD

VIRTUALENV — VIRTUALENV 20.4.7.DEV5+GCECAFAA DOCUMENTATION Virtualenv¶. virtualenv is a tool to create isolated Python environments. Since Python 3.3, a subset of it has been integrated into the standard library under the venv module.The venv module does not offer all features of this library, to name just a few more prominent: is slower (by not having the app-data seed method),. is not as extendable, cannot create virtual environments for BASIC USAGE OF PIPENV ☤ Pipfile.lock Security Features¶. Pipfile.lock takes advantage of some great new security improvements in pip.By default, the Pipfile.lock will be generated with the sha256 hashes of each downloaded package. This will allow pip to guarantee you’re installing what you intend to when on a compromised network, or downloading dependencies from an untrusted PyPI endpoint. PIPENV & VIRTUAL ENVIRONMENTS Pipenv manages dependencies on a per-project basis. To install packages, change into your project’s directory (or just an empty directory for this tutorial) and run: $ cd myproject $ pipenv install requests. Pipenv will install the excellent Requests library and create a Pipfile for you in your project’s directory. COMMANDS - PIP DOCUMENTATION V21.1.2 Commands. ¶. The general options that apply to all the commands listed below can be found under the pip page in this section. Environment Management and Introspection. pip install. pip uninstall. pip list. pip freeze. pip check. ADVANCED USAGE OF PIPENV You can then run pipenv run in your terminal to run the command in the context of your pipenv virtual environment even if you have not activated the pipenv shell first. For example, in your Pipfile: printspam = "python -c \"print ('I am a silly example, no one would need to do this')\"". PIP FREEZE - PIP DOCUMENTATION V21.1.2 To solve that issue, you can try one of the followings: Install the command for yourself (e.g. in your home directory). Ask the system admin to allow this command for all users. Check and correct the PATH variable of your own environment. Check the ACL (Access-Control List)for this command.

DEVELOPMENT
Development. ¶. pip is a volunteer maintained open source project and we welcome contributions of all forms. The sections below will help you get started with development, testing, and documentation. You can also join #pypa (general packaging discussion and user support) and #pypa-dev (discussion about development of packaging tools) on PIP CACHE - PIP DOCUMENTATION V21.1.2 Inspect and manage pip’s wheel cache. Subcommands: dir: Show the cache directory. info: Show information about the cache. list: List filenames of packages stored in the cache. remove: Remove one or more package from the cache. purge: Remove all items from the cache. can be a glob expression or a package name. PIP - PIP DOCUMENTATION V21.2.DEV0 pip offers the --log option for specifying a file where a maximum verbosity log will be kept. This option is empty by default. This log appends to previous logging. Like all pip options, --log can also be set as an environment variable, or placed into the pip config file. See the Configuration section. PIP LIST - PIP DOCUMENTATION V21.1.2 Description¶. List installed packages, including editables. Packages are listed in a case-insensitive sorted order. Options¶-o, --outdated¶. List outdated packagesREFERENCE GUIDE

When you install pip, a pip command is added to your system, which can be run from the command prompt as follows: Unix/macOS. python -m pip . python -m pip executes pip using the Python interpreter you specified as python.INSTALLATION
virtualenv is a CLI tool that needs a Python interpreter to run. If you already have a Python 3.5+ interpreter the best is to use pipx to install virtualenv into an isolated environment. This has the added benefit that later you’ll be able to upgrade virtualenv without affecting other parts of the system. pipx install virtualenvvirtualenv
FREQUENTLY ENCOUNTERED PIPENV PROBLEMS Make sure your dependencies actually do resolve. If you’re confident they are, you may need to clear your resolver cache. Run the following command: and try again. If this does not work, try manually deleting the whole cache directory. It is usually one of the following locations: ~/.cache/pipenv (other operating systems) Pipenv does notNAVIGATION

PYTHON PACKAGING AUTHORITY¶ The Python Packaging Authority (PyPA) is a working group that maintains a core set of software projects used in Python packaging. The software developed through the PyPA is used to package, share, and install Python software and to interact with indexes of downloadable Python software such as PyPI , the Python Package Index. Click the logo below to download pip, the most prominent software used to interact with PyPI. The PyPA publishes the Python Packaging User Guide , which is THE AUTHORITATIVE RESOURCE ON HOW TO PACKAGE, PUBLISH, AND INSTALL PYTHON PROJECTS USING CURRENT TOOLS. The User Guide provides a user introduction to packaging, and explains how to use these tools. In case you need to package Python with other languages (for example, in a scientific Python package), the user guide also offers basic information about and links to available third-party packaging options (for example, conda-forge).
For a listing of PyPA’s important projects, see the key projectslist . The
PyPA hosts projects on GitHub and Bitbucket , and discusses issues in the Packaging category on discuss.python.org and on the distutils-sigmailing list.
