Python Requests: No Module Named Certifi

If you are using Python Requests library to make HTTP requests and you come across an error message that says "No module named certifi", you may be wondering what's going on. In this article, I'll explain what this error means and how to resolve it.

What is Certifi?

Certifi is a Python package that contains a set of root certificates for verifying the authenticity of SSL/TLS certificates used by HTTPS servers. When you use Python Requests library to make an HTTPS request, it needs to verify the server's SSL/TLS certificate to ensure that you are connecting to the right server and that your communication is secure. Python Requests library uses the Certifi package to do this verification.

What Causes the "No module named certifi" Error?

The "No module named certifi" error occurs when Python Requests library cannot find the Certifi package in your Python environment. This can happen for several reasons:

  • You haven't installed Certifi package.
  • You have installed Certifi package, but it's not in the Python path.
  • You have installed Python Requests library in a virtual environment, but you haven't installed Certifi package in that environment.

How to Resolve the Issue?

To resolve the "No module named certifi" error, you need to make sure that Certifi package is installed and available in your Python environment. Here are a few ways to do that:

Option 1: Install Certifi Package via pip

The easiest way to install Certifi package is via pip, which is a package manager for Python. Open your command prompt or terminal and run the following command:


pip install certifi

This will install the Certifi package in your Python environment.

Option 2: Check if Certifi Package is Installed

You can check if Certifi package is installed in your Python environment by running the following command:


pip freeze | grep certifi

If the output shows "certifi" followed by a version number, it means that Certifi package is installed.

Option 3: Install Python Requests Library in a Virtual Environment

If you are using a virtual environment to manage your Python projects, make sure that you install Certifi package in that environment. Here are the steps:

  1. Create a virtual environment: python -m venv env
  2. Activate the environment: source env/bin/activate (on Linux/Mac) or env\Scripts\activate.bat (on Windows)
  3. Install Python Requests library: pip install requests
  4. Install Certifi package: pip install certifi

Now, you can use Python Requests library to make HTTPS requests without encountering the "No module named certifi" error.

Conclusion

The "No module named certifi" error is a common issue that you may encounter when using Python Requests library. This error occurs when Python Requests library cannot find the Certifi package in your Python environment. To resolve this issue, you need to make sure that Certifi package is installed and available in your Python environment. You can install it via pip or check if it's already installed. If you are using a virtual environment, make sure that you install Certifi package in that environment as well.
