How do I install a specific version of urllib3?

To install a specific version of urllib3 in Python, you can use pip, which is the standard package manager for Python. The following command will install a specific version of the urllib3 package:

pip install urllib3==<version>

Replace <version> with the version number you want to install. For example, if you want to install version 1.25.11 of urllib3, you would run:

pip install urllib3==1.25.11

If you're using a requirements.txt file for your project, you can specify the version of urllib3 you need by adding the following line to the file:


Then, you can install all the dependencies listed in your requirements.txt file with:

pip install -r requirements.txt

Using a Virtual Environment

Before installing packages, it's often a good practice to use a virtual environment to avoid conflicts with other projects or system-wide packages. Here's how to create and activate a virtual environment:

For Unix/macOS:

python3 -m venv venv
source venv/bin/activate

For Windows:

python -m venv venv

After activating the virtual environment, you can install the specific version of urllib3 as mentioned above.

Checking the Installed Version

After installation, you can check that the correct version of urllib3 is installed by running:

pip show urllib3

This will display information about the urllib3 package, including the version number.

Upgrading or Downgrading urllib3

If you already have urllib3 installed and want to upgrade or downgrade to a specific version, you can use the following command:

pip install --upgrade urllib3==<version>

Or, to downgrade:

pip install urllib3==<version>

Replace <version> with the desired version number.

Remember to regularly check for updates to urllib3 and other dependencies to ensure you have the latest security patches and features. You can do this with:

pip install --upgrade urllib3

This will upgrade urllib3 to the latest version available.

Always be cautious when installing, upgrading, or downgrading packages, as changes may affect the functionality of your Python application. Make sure to test your application after making changes to the dependencies.
