How to install and use Pip3

install and use pip3
Pip3 is the official package manager and pip command for Python 3. It enables the installation and management of third party software packages with features and functionality not found in the Python standard library. Pip3 installs packages from PyPI (Python Package Index), but won’t resolve dependencies or help you solve dependency conflicts.
The ActiveState Platform’s command line interface, the State Tool will automatically resolve dependencies for you to ensure your Python environment won’t be corrupted by installing incompatible dependencies.

pip3 installation guide

Installation Prerequisites 

Check if pip3 is already installed by entering the following command in a terminal or command line:

pip3 -v

Output should be similar to:

C:\Python38\python.exe -m pip <command> [options]
  install      Install packages.
  download                    Download packages.
  uninstall                   Uninstall packages.
  freeze                      Output installed packages in requirements format.
  list                        List installed packages.
  show                        Show information about installed packages.

You can also check to see which version of pip3 is installed by entering:

pip3 --version

Output should be similar to:

pip 20.0.2 from C:\Python38\lib\site-packages\pip (python 3.8)

Confirm which version of Python (if any) is installed on your computer by entering:

python --version 

Output should be similar to:

Python 3.8.2 

Pip3 Installation

Python 3.4+ in most operating systems includes pip3 by default. If your python version is less than 3.4, then you should upgrade your Python version which will automatically install pip3.
For example, you can install the latest version of Python from ActiveState (Python 3.9), which includes pip3.

Pip3 Upgrade

In operating system environments that already have Python 3 and pip3 installations, you can upgrade pip3, by entering:

python -m pip3 install --upgrade pip
Pip3 Downgrade

You can downgrade to a previous version of pip3, in case a newer version is causing unexpected compatibility errors. For example, to downgrade to pip3 v19.0 run the following command:

python -m pip3 install pip==19.0

Pip3 Virtualenv and Venv
When pip3 is used in a virtual environment, it will generally install packages in a path similar to: 

Pip3 Usage

To install a Python package, enter:

Pip3 install <package_name>

Linux and MacOS have system Python, that you should leave alone if possible. System Python is configured to help the operating system work as intended.

Install pip3 Ubuntu and Debian Linux

Ubuntu 18.04 has both Python 2 and Python 3 installed by default, and hence has two pip variants for each Python version. ‘pip’, refers to Python 2. pip3 refers to Python 3.
Ubuntu 20.4 has only Python 3, but still requires a separate python-pip 3 installation.
Procedure for installing pip3 on Ubuntu and Debian Linux:
Enter the following command to update Linux:

sudo apt update

Enter the following command to install pip3:

sudo apt install python3-pip

The above command will also install all pip3 dependencies.
To find the location where pip3 installs packages in Ubuntu Linux, enter:

which pip3 

Output should be similar to:


Install pip3 Windows

To install or upgrade pip3 in a Windows environment that already has Python 3 installed:
Download the latest version of from


You can also use the curl command to download 

curl -o

CD into the directory where was downloaded to, and enter the following command to install pip3 and its dependencies:


You can verify that pip3 is installed by navigating to the default pip3 installation directory, eg. C:\python38\scripts\, and enter:

pip3 --version

Add Pip3 to Windows Environment Variables

A common problem with running Python tools such as pip3 in Windows, is not having it in the environment path so that you can access it from anywhere. In most cases, you can navigate to the default <python_dir>/scripts directory in which the tool is installed in order to run it.
To run pip3 from any location, you need to add the directory in which it is installed in, as a System PATH environment variable:

  1. Open the Control Panel and navigate to System.
  2. Click on Advanced system settings in the upper left panel.
  3. Click on Environment Variables.
  4. Under System Variables, scroll down then double-click the PATH variable.
  5. Click New, and add the directory where pip3 is installed, 

e.g.C:\Python38\Scripts , and select OK.
Figure 1: Environment Variables: Directory where pip3 is installed:
pip3 environment variable

Install Pip3 MacOS 

To install pip3 in a MacOS environment that already has Python 3 installed, enter:
sudo apt install python3-pip 
To install pip3 using the Homebrew package manager (if it is installed), enter:

brew install pip3

You can also install pip3 using

  • Download the latest version of from
  • CD into the download directory, and enter the following command: 
sudo python3 will install pip3 for the python version which runs the script.

Pip3 and Conda 

Pip3 has limited use in the Conda environment compared to other operating system environments.
Conda has many of the features found in pip3, but is otherwise a completely separate tool. It installs python modules and packages from the Anaconda Repository. Only after Conda has been used to install as many packages as possible in a project, should pip3 be used to install any remaining software.
It depends on whether you are familiar with pip3 and Conda, and with how package installations interact between the two methods. If you are relatively new to Conda and Python, then only use Conda to install packages in Conda environments. Otherwise pip3 can be used to install packages not found in the Anaconda Repository. Extra care needs to be taken with pip3 dependencies so that they do not conflict with Conda packages and dependencies.
If Python 3 and pip3 are installed outside of the Conda environment, then you can run pip3 from an Anaconda prompt just as you would from a Linux or Windows terminal or command line.

A modern solution to Python package management – Try ActiveState’s Platform

The ActiveState Platform is a cloud-based build tool for Python. It provides build automation and vulnerability remediation for:

  • Python language cores, including Python 2.7 and Python 3.5+
  • Python packages and their dependencies, including:
  • Transitive dependencies (ie., dependencies of dependencies)
  • Linked C and Fortran libraries, so you can build data science packages
  • Operating system-level dependencies for Windows, Linux, and macOS
  • Shared dependencies (ie., OpenSSL)
  • Find, fix and automatically rebuild a secure version of Python packages like Django and environments in minutes

Python Package Management In Action

Get a hands-on appreciation for how the ActiveState Platform can help you manage your dependencies for Python environments. Just run the following command to install Python 3.9 and our package manager, the State Tool:

powershell -Command "& $([scriptblock]::Create((New-Object Net.WebClient).DownloadString(''))) -activate-default ActiveState-Labs/Python-3.9Beta"


sh <(curl -q --activate-default ActiveState-Labs/Python-3.9Beta

Now you can run state install <packagename>. Learn more about how to use the State Tool to manage your Python environment.
