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 :ref:`Virtual Environment <pypug:Creating and using Virtual Environments>` created by :ref:`pypug:virtualenv` or :ref:`pyvenv <pypug:venv>`. Just make sure to :ref:`upgrade pip <Upgrading pip>`.
Installing with get-pip.py
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
As when running any script downloaded from the web, ensure that you have reviewed the code and are happy that it works as you expect. Then run the following:
Be cautious if you are using a Python install that is managed by your operating
system or another package manager.
get-pip.py does not coordinate with
those tools, and may leave your system in an inconsistent state.
get-pip.py also installs :ref:`pypug:setuptools`  and :ref:`pypug:wheel`
if they are not already. :ref:`pypug:setuptools` is required to install
:term:`source distributions <pypug:Source Distribution (or "sdist")>`. Both are
required in order to build a :ref:`Wheel cache` (which improves installation
speed), although neither are required to install pre-built :term:`wheels
The get-pip.py script is supported on the same python version as pip. For the now unsupported Python 2.6, alternate script is available here.
.. option:: --no-setuptools If set, do not attempt to install :ref:`pypug:setuptools`
.. option:: --no-wheel If set, do not attempt to install :ref:`pypug:wheel`
Install from local copies of pip and setuptools:
python get-pip.py --no-index --find-links=/local/copies
Install to the user site :
python get-pip.py --user
Install behind a proxy:
python get-pip.py --proxy="http://[user:passwd@]proxy.server:port"
get-pip.py can also be used to install a specified combination of
wheel using the same requirements syntax as
python get-pip.py pip==9.0.2 wheel==0.30.0 setuptools==28.8.0
Using Linux Package Managers
On Linux or macOS:
pip install -U pip
On Windows :
python -m pip install -U pip
Python and OS Compatibility
pip works with CPython versions 2.7, 3.4, 3.5, 3.6, 3.7 and also pypy.
This means pip works on the latest patch version of each of these minor versions. Previous patch versions are supported on a best effort approach.
pip works on Unix/Linux, macOS, and Windows.
