     > 💁 By default when you install a package it is available everywhere on your computer, and this can lead to problems with package versions - such as one application depending on one version of a package that breaks when you install a new version for a different application. To work around this problem, you can use a [Python virtual environment](https://docs.python.org/3/library/venv.html), essentially a copy of Python in a dedicated folder, and when you install Pip packages they get installed just to that folder. You won't be using virtual environments when using your Pi. The Grove install script installs the Grove Python packages globally, so to use a virtual environment you would need to set up a virtual environment then manually re-install the Grove packages inside that environment. It's easier to just use global packages, especially as a lot of Pi developers will re-flash a clean SD card for each project.
