When working in environments with restricted internet access, you may need to configure pip to use a proxy to download Python packages. In this tutorial, we'll walk through the steps of using the pip install command with a proxy option.
Before proceeding, ensure that Python and pip are installed on your system. Open a terminal or command prompt and run the following commands:
Make sure both commands return the expected version numbers.
You'll need the following information about your proxy:
Before using pip install with a proxy, set the relevant environment variables. Open your terminal or command prompt and enter the following commands, replacing the placeholder values with your proxy information:
If your proxy does not require a username and password, omit them from the URLs.
Now that you've set up the proxy environment variables, you can use pip install as usual. For example, let's install the requests library:
If your proxy requires authentication, you may need to provide the --proxy option with the appropriate URL. For example:
Replace the placeholder values with your actual proxy information.
After the installation is complete, verify that the package has been installed successfully. You can do this by running a simple Python script that imports the installed package:
This should print the version of the requests library.
By following these steps, you can successfully use pip install with a proxy, allowing you to work with Python packages in environments with restricted internet access. Adjust the proxy settings as needed based on your specific proxy configuration.
