WARNING: Running pip as the 'root' user can result in broken permissions and conflicting behaviour with the system package manager. It is recommended to use a virtual environment instead: https://pip.pypa.io/warnings/venv

Thank you for the warning! It is indeed good practice to use a virtual environment when using pip. Virtual environments provide a way to isolate Python environments and avoid conflicts with the system package manager.

To create a virtual environment, follow these steps:

Install the virtualenv package if you haven't already:
```
$ pip install virtualenv
```
Navigate to the directory where you want to create the virtual environment.
Create the virtual environment:
```
$ virtualenv env
```
This command creates a directory named env containing the isolated Python environment.
Activate the virtual environment:
- On Unix or Linux:
```
$ source env/bin/activate
```
- On Windows:
```
$ .\env\Scripts\activate
```
After activation, your terminal prompt will change to indicate that you are working within the virtual environment.
Install packages using pip:
```
$ pip install package_name
```
To exit the virtual environment, use the deactivate command:
```
$ deactivate
```

By using a virtual environment, you can ensure that the installation and management of Python packages are contained within the environment, avoiding system-level conflicts.
