### Download and install Python libraries
The Pebble SDK depends on Python libraries to convert fonts and images from your
computer into Pebble resources.
{% if include.mac %}
You need to use the standard Python `easy_install` package manager to install
the alternative `pip` package manager. This is then used to install other Python
dependencies.
Follow these steps in Terminal:
{% endif %}
1. Install `pip` and `virtualenv`:
```bash
{% if include.mac %}sudo easy_install pip{% else %}sudo apt-get install python-pip python2.7-dev{% endif %}
sudo pip install virtualenv
```
2. Install the Python library dependencies locally:
```bash
cd {{ site.data.sdk.path }}pebble-sdk-{{ site.data.sdk.pebble_tool.version }}-{% if include.mac %}mac{% else %}linux64{% endif %}
virtualenv --no-site-packages .env
source .env/bin/activate
{% if include.mac %}CFLAGS="" {% endif %}pip install -r requirements.txt
deactivate
```
> **Note: virtualenv is not optional.**
