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:

   {% 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:

   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.
