To install pip for Python 3 on Ubuntu, first update your package repository and then install the python3-pip package using sudo apt update followed by sudo apt install python3-pip.
After installation, verify the setup by checking the version with pip3 --version. To ensure you have the latest version, upgrade pip using sudo pip3 install --upgrade pip.
Prerequisites: You need an Ubuntu system with a user account that has sudo privileges and access to the terminal.
Verification: If
pip3 --versionreturns a number, the software is configured correctly; otherwise, you may need to install Python 3 first viasudo apt install python3.Alternative Methods: If the package manager method fails or you lack root access, you can bootstrap pip by downloading
get-pip.pyand running it withpython3 get-pip.py, though this may leave the system in an inconsistent state if not managed carefully.Virtual Environments: For project-specific isolation, it is recommended to create a virtual environment using
python3 -m venv my_envand then activate it before installing packages.
I believe that you can install it on Ubuntu with
sudo apt-get install python-pip
or
sudo apt-get install python3-pip
for Python 3. Sure, it's an older version but its functionality is there.

Try download install package from https://pypi.python.org/pypi/pip#downloads and use python setup.py install
It seems python3-pip is not installed correctly on my system so I did
sudo apt install --reinstall python3-pip
Now I can install programs with pip3.
These all failed for me, I had to run via a manual download:
wget https://bootstrap.pypa.io/get-pip.py
sudo python3 get-pip.py

PyPI is the Python Package index — repository of python modules.
pip is used to download and install packages directly from PyPI. PyPI is hosted by Python Software Foundation. It is a specialized package manager that only deals with python packages.
apt-get is used to download and install packages from Ubuntu repositories which are hosted by Canonical.
Some of the differences between installing python packages from apt-get and pip are as follows:
Canonical only provides packages for selected python modules. Whereas, PyPI hosts a much broader range of python modules. So, there are a lot of python modules which you won't be able to install using
apt-get.Canonical only hosts a single version of any package (generally the latest or the one released in recent past). So, with
apt-getwe cannot decide the version of python-package that we want.piphelps us in this situation. We can install any version of the package that has previously been uploaded on PyPI. This is extremely helpful in case of conflict in dependencies.apt-getinstalls python modules in system-wide location. We cannot just install modules in our project virtualenv.pipsolves this problem for us. If we are usingpipafter activating the virtualenv, it is intelligent enough to only install the modules in our project virtualenv. As mentioned in previous point, if there is a version of a particular python package already installed in system-wide location, and one of our project requires an older version of the same python package, in such situations we can use virtualenv and pip to install that older version of python package without any conflicts.As @Radu Rădeanu pointed out in this answer, there would generally be difference in names of packages as well. Canonical usually names Python 2 packages as
python-<package_name>and Python 3 packages aspython3-<package_name>. Whereas forpipwe generally just need to use<package_name>for both Python 2 as well as Python3 packages.
Which one should you use:
Both apt-get and pip are mature package managers which automatically install any other package dependency while installing. You may use anyone as you like. However, if you need to install a particular version of python-package, or install the package in a virtualenv, or install a package which is only hosted on PyPI; only pip would help you solve that issue. Otherwise, if you don't mind installing the packages in system-wide location it doesn't really matter whether you use apt-get or pip.
As @AvinashRaj said in his comment, pip is used to install python packages only, but apt-get is used to install packages created in any programming language.
Your main problem is to find the right package name in both cases:
pip search pyudev
will give you the right name for the package you want to install using pip install, as
apt-cache search pyudev
will give you the right name for the package you want to install using apt-get install:
radu@Radu: ~ $ pip search pyudev
pyudev - A libudev binding
radu@Radu: ~ $ apt-cache search pyudev
python-pyudev - Python bindings for libudev
python3-pyudev - Python3 bindings for libudev
So, in conlusion, the correspondent of sudo apt-get install python-pyudev is sudo pip install pyudev, not sudo pip install python-pyudev.
Now depends on you what you want to choose when you want to install a python package: pip or apt-get. See for example this Q&A about difference in installing a package using pip and apt-get.
I'm trying to install a few python packages on my Ubuntu 24.04 machine running KDE Plasma, the Python interpreter can be invoked with python3 in a terminal window, however, using pip or pip3 to install a package, it returns this error:
$ pip3 install pytube
error: externally-managed-environment
× This environment is externally managed
╰─> To install Python packages system-wide, try apt install
python3-xyz, where xyz is the package you are trying to
install.
If you wish to install a non-Debian-packaged Python package,
create a virtual environment using python3 -m venv path/to/venv.
Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make
sure you have python3-full installed.
If you wish to install a non-Debian packaged Python application,
it may be easiest to use pipx install xyz, which will manage a
virtual environment for you. Make sure you have pipx installed.
See /usr/share/doc/python3.12/README.venv for more information.
note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages.
hint: See PEP 668 for the detailed specification.i've read here (https://docs.python-guide.org/dev/virtualenvs/#virtualenvironments-ref) that i can use pipenv to install packages only for my projects, rather than installing them system-wide, but it requires pip, which i can't access due to the error.
when creating a virtual environment in VS Code i can choose between 2 interpreters:
i chose the "Global" one and it doesn't let me create it. Returns an error:
VenvError: CREATE_VENV.VENV_FAILED_CREATION 2024-08-09 19:47:57.063 [error] Error while running venv creation script: CREATE_VENV.VENV_FAILED_CREATION 2024-08-09 19:47:57.064 [error] CREATE_VENV.VENV_FAILED_CREATION
I hope I'm right and the problem is with your PATH, try this
You can add this to your ~/.bashrc file:
PATH=$PATH:~/.local/bin
If you don't know how, you can just execute this line in a Terminal:
echo "PATH=\$PATH:~/.local/bin" >> ~/.bashrc
You can also check what's in your PATH by typing in the Terminal
echo $PATH
