Installing pip

Introduction

After installing Python, the next step in setting up your Selenium automation environment is installing pip.

pip is Python’s official package manager. It allows you to install, update, uninstall, and manage third-party Python packages with simple commands.

In Selenium automation, pip is used to install essential libraries such as Selenium, PyTest, WebDriver Manager, Requests, and many other packages required for building automation frameworks.

In this tutorial, you’ll learn what pip is, how to install it on Windows, macOS, and Linux, verify the installation, and follow best practices.

What is pip?

pip stands for Preferred Installer Program.

It is the default package manager for Python and is used to download and install packages from the Python Package Index (PyPI).

Instead of manually downloading libraries from different websites, pip installs them using a single command.

For example, Selenium can be installed using:

pip install selenium

Why is pip Required?

pip makes package management simple and efficient.

It allows you to:

  • Install Python packages

  • Update existing packages

  • Uninstall packages

  • Manage package versions

  • Install project dependencies

  • Build automation frameworks

Without pip, installing and maintaining Python libraries would be much more difficult.

Check if pip is Already Installed

Modern versions of Python (Python 3.4 and above) include pip by default.

Before installing pip, verify whether it is already available.

Windows

Open Command Prompt and run:

pip --version

macOS / Linux

Open Terminal and run:

pip3 --version

Example Output

pip 25.x.x from ...

If the version is displayed, pip is already installed and ready to use.

Installing pip on Windows

If pip is not installed, follow these steps.

Step 1: Download get-pip.py

Download the get-pip.py installation script from the official Python Packaging Authority.

Save the file to your computer.

Step 2: Open Command Prompt

Navigate to the folder containing get-pip.py.

Example:

cd Downloads

Step 3: Install pip

Run the following command:

python get-pip.py

Wait for the installation to complete.

Step 4: Verify Installation

Run:

pip --version

If the version number appears, pip has been installed successfully.

Installing pip on macOS

Most recent Python installations on macOS include pip automatically.

If pip is missing:

Step 1: Download get-pip.py

Download the get-pip.py script.

Step 2: Install pip

Run:

python3 get-pip.py

Step 3: Verify Installation

pip3 --version

Installing pip on Linux

Most Linux distributions install pip separately.

Ubuntu / Debian

Update package information:

sudo apt update

Install pip:

sudo apt install python3-pip

Verify:

pip3 --version

Fedora

Install pip:

sudo dnf install python3-pip

Verify:

pip3 --version

CentOS / RHEL

Install pip:

sudo yum install python3-pip

Verify:

pip3 --version

Installing Your First Python Package

Once pip is installed, you can install Python packages.

For example, install Selenium:

pip install selenium

On macOS or Linux, you may use:

pip3 install selenium

pip automatically downloads and installs Selenium along with its required dependencies.

Upgrading pip

It is recommended to keep pip updated.

Windows

python -m pip install --upgrade pip

macOS / Linux

python3 -m pip install --upgrade pip

Useful pip Commands

Check pip Version

pip --version

List Installed Packages

pip list

Show Package Information

pip show selenium

Upgrade a Package

pip install --upgrade selenium

Uninstall a Package

pip uninstall selenium

Common Installation Issues

pip Command Not Recognized

Error

'pip' is not recognized as an internal or external command

Solution

Ensure Python is installed correctly and that the Python Scripts directory has been added to the system PATH.

Permission Denied

Error

Permission denied

Solution

Use administrator privileges or the sudo command on Linux/macOS.

Example:

sudo pip3 install selenium

Multiple Python Versions

If multiple Python versions are installed, use:

python -m pip --version

or

python3 -m pip --version

to ensure you’re using the correct pip installation.

Best Practices

  • Use the latest version of pip.

  • Install packages only from trusted sources such as PyPI.

  • Keep project dependencies updated.

  • Use virtual environments for Selenium projects.

  • Verify package installation after every install.

  • Avoid installing unnecessary global packages.
