edit: Manual installation and use of setuptools is not the standard process anymore.
If you're running Python 2.7.9+ or Python 3.4+
Congrats, you should already have pip installed. If you do not, read onward.
If you're running a Unix-like System
You can usually install the package for pip through your package manager if your version of Python is older than 2.7.9 or 3.4, or if your system did not include it for whatever reason.
Instructions for some of the more common distros follow.
Installing on Debian (Wheezy and newer) and Ubuntu (Trusty Tahr and newer) for Python 2.x
Run the following command from a terminal:
sudo apt-get install python-pip
Installing on Debian (Wheezy and newer) and Ubuntu (Trusty Tahr and newer) for Python 3.x
Run the following command from a terminal:
sudo apt-get install python3-pip
On a fresh Debian/Ubuntu install, the package may not be found until you do:
sudo apt-get update
Installing pip on CentOS 7 for Python 2.x
On CentOS 7, you have to install setup tools first, and then use that to install pip, as there is no direct package for it.
sudo yum install python-setuptools
sudo easy_install pip
Installing pip on CentOS 7 for Python 3.x
Assuming you installed Python 3.4 from EPEL, you can install Python 3's setup tools and use it to install pip.
# First command requires you to have enabled EPEL for CentOS7
sudo yum install python34-setuptools
sudo easy_install pip
If your Unix/Linux distro doesn't have it in package repos
Install using the manual way detailed below.
The manual way
If you want to do it the manual way, the now-recommended method is to install using the get-pip.py script from pip's installation instructions.

How to install pip with Python 3? - Stack Overflow
Pip install
ELI5: when I pip install something, where does it actually get installed?
Packages are installed in the 'sites-packages' path in your system when you install them through PIP, you can view any package's specific path by running pip show <pkgname> for example the pip package itself (on my system)
$ pip show pip Name: pip Version: 20.0.2 Summary: The PyPA recommended tool for installing Python packages. Home-page: https://pip.pypa.io/ Author: The pip developers Author-email: pypa-dev@groups.google.com License: MIT Location: /usr/local/lib/python3.7/site-packages Requires: Required-by:
From the location directive the sites-packages path is /usr/local/lib/python3.7/site-packages on my machine.
You can also run this command python -m site which will list the paths Python will actually look through to find any imported package!
And yes they do consume space once installed.
Side note, it is generally a very bad idea to just install PIP packages directly, since they are installed globally/per-user by default. This means that all projects by default share the same packages installed this is bad for multiple reasons, for example you could use a package you don't declare in your dependencies and have the code you write break when you move it to a different machine since when you pip install it won't download the package since you didn't document it in the requirements.txt!
Also it could cause conflicts between versions of the same packages between projects and cause unintended incompatibilities if you don't pay attention to managing them!
Ideally you'd want to be using tools like Virtualenv and Pipenv to make those packages per-project! It'll probably be worth the time to learn tools like those and incorporate them in your flow.
Hope this isn't too long lol :D cheers
More on reddit.comPip installed in Python 3.9?
Never thought I'd need to ask this question as a CCNA and Network+ holder, I guess Python has decided to make the simple act of a pip install THIS difficult, wow! I have Python installed as well as Virtual Studio Code. I try this from command prompt
pip3 install requests File "<stdin>", line 1 pip3 install requests ^^^^^^^
And that's all I get, again and again and again. So I try this in the Visual Studio terminal:
pip3 : The term 'pip3' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the
spelling of the name, or if a path was included, verify that the path is correct and try again. At line:1 char:1

Mind blowing stuff here. I JUST want to be able to pip install. I've also tried just using "pip" and leaving out the 3. What mountains must I move to perform such a basic task? I
