Do I need to install pip?¶

pip is already installed if you are using Python 2 >=2.7.9 or Python 3 >=3.4downloaded from python.org or if you are workingin a Virtual Environmentcreated by virtualenv or venv. Just make sureto upgrade pip.

Sep 19, 2018 To pip install OpenCV on your Raspberry Pi system, be sure to use sudo like this: $ sudo pip install opencv-contrib-python4.1.0.25 2019-11-21 Update: Readers have reported that some versions of OpenCV 4 as installed via pip do not work properly on the Raspberry Pi. (pip maintainer here!) If the package is not a wheel, pip tries to build a wheel for it (via setup.py bdistwheel).If that fails for any reason, you get the 'Failed building wheel for pycparser' message and pip falls back to installing directly (via setup.py install).

Use the following command to check whether pip is installed:

Using Linux Package Managers¶

Warning

If you installed Python from a package manager on Linux, you should alwaysinstall pip for that Python installation using the same source.

See pypug:Installing pip/setuptools/wheel with Linux Package Managersin the Python Packaging User Guide.

Here are ways to contact a few Linux package maintainers if you run intoproblems:

• Debian Python Team (for generalissues related to apt)

pip developers do not have control over how Linux distributions handle pipinstallations, and are unable to provide solutions to related issues ingeneral.

Using ensurepip¶

Python >=3.4 can self-bootstrap pip with the built-inensurepip module. Refer to the standard librarydocumentation for more details. Make sure to upgrade pipafter ensurepip installs pip.

See the Using Linux Package Managers section if your Python reportsNomodulenamedensurepip on Debian and derived systems (e.g. Ubuntu).

Installing with get-pip.py¶

Warning

Be cautious if you are using a Python install that is managed by your operatingsystem or another package manager. get-pip.py does not coordinate withthose tools, and may leave your system in an inconsistent state.

To manually install pip, securely 1 download get-pip.py by followingthis link: get-pip.py. Alternatively, use curl:

Then run the following command in the folder where youhave downloaded get-pip.py:

get-pip.py also installs setuptools2 and wheelif they are not already. setuptools is required to installsource distributions. Both arerequired in order to build a Wheel Cache (which improves installationspeed), although neither are required to install pre-built wheels.

Note

The get-pip.py script is supported on the same python version as pip.For the now unsupported Python 2.6, alternate script is availablehere.

get-pip.py options¶

If set, do not attempt to install setuptools

If set, do not attempt to install wheel

get-pip.py allows pip install options and the general options. Below aresome examples:

Install from local copies of pip and setuptools:

get-pip.py can also be used to install a specified combination of pip,setuptools, and wheel using the same requirements syntax as pip:

Upgrading pip¶

Python and OS Compatibility¶

pip works with CPython versions 3.6, 3.7, 3.8 and also PyPy.

This means pip works on the latest patch version of each of these minorversions. Previous patch versions are supported on a best effort approach.

pip works on Unix/Linux, macOS, and Windows.

“Secure” in this context means using a modern browser or atool like curl that verifies SSL certificates when downloading fromhttps URLs.

Pip Install Os X 10 11 4

Beginning with pip v1.5.1, get-pip.py stopped requiring setuptools tobe installed first.

The pip developers are considering making --user the default for allinstalls, including get-pip.py installs of pip, but at this time,--user installs for pip itself, should not be considered to be fullytested or endorsed. For discussion, see Issue 1668.
