Virtualenv is a tool that allows to manage dependencies across the project in a consistent manner. In other words, if there are some specific packages that are needed, you can create a virtual environment and place those versioned packages there.

Main advantage is separation of projects' ecosystems. If I were to install packages globally then I would have some hard time maintaining different projects on my local machine, mainly due to some packages with specific version being used across all of my projects.
