Some example libraries that would fit this description would be Numpy and Pandas, a REPL alternative like ipython, or complete environments like Jupyter Notebook. This is only recommended for the more generic packages that you might need in a lot of scripts, or if the package functions as a more generic tool. Having said that, you can also install packages outside of a Python venv. Because everything in our venv is installed locally, you don’t need to become a superuser with sudo or su and you don’t risk package version conflicts. And the good news: pip is present inside your virtual environment by default. I can’t stress this enough: preferably, you install packages inside a virtual environment. $ python3 get-pip.py Pip Install Python packages If these methods fail, you can also download a Python script that will install pip for you, with the following commands: $ curl "" -o "get-pip.py" Pip is part of EPEL (Extra Packages for Enterprise Linux), so you might need to enable that first. If your system uses the yum package manager, you can try the following: $ sudo yum install python-pip It’s the most recommended method and ensures your system will stay in a consistent state. You can install pip with the apt package manager on Debian, Ubuntu, Linux Mint, and other Debian derivatives. Install Pip on Linux (Ubuntu, Debian, Redhat) Make sure you are in the directory where the script was downloaded. Download the file and run it with Python from a command prompt or terminal window: python3 get-pip.py On Windows and Mac, you can download a Python script to install pip, called get-pip.py. You should do this only as a last resort, and I strongly suggest you first check if your Python installation went well first. If that failed too, you need to install it yourself, so let’s take a look at how you can manually install it. If that didn’t work either, you can try the pip module that is built into most modern Python installations: python3 -m pip help On those systems, pip is often installed under the name pip3: pip3 help Python 2 and 3 can be installed next to each other on some systems. If the pip command gives an error, try pip3 instead. Open a terminal (Linux/MacOS) or a Windows shell, and type in the following command: pip help

So before you try to install Pip, make sure it’s not already present on your system. Python’s pip is already installed if you are using Python 2 >=2.7.9 or Python 3 >=3.4 downloaded from . If you are working in a virtual environment, pip also gets installed for you. The good news is that Pip is probably already present on your system.
