As a developer, it's important to have the correct permissions set on your command-line interface. This is where the --user option comes in handy. In this guide, we'll go over what the --user option is, how to use it, and how it can help you avoid errors.
What is the --user Option?
The --user option is a command-line option that tells the system to install packages in the current user's home directory. This means that you don't need to have administrator privileges to install packages, which can be helpful in certain situations.
How to Use the --user Option
To use the --user option, simply add it to the end of your command. For example, instead of using:
sudo pip install requests
you can use:
pip install --user requests
This will install the requests package in your home directory, without needing administrator privileges.
Benefits of Using the --user Option
Using the --user option has several benefits, including:
- You don't need administrator privileges to install packages
- Packages are installed in your home directory, making them easy to find and manage
- You can easily create a virtual environment without needing to use
sudo
