Updated only for PlatformIO 3.0
In order to avoid some issues with libraries, I recommend updating to the latest teensy platform and PlatformIO from development branches.

# uninstall teensy platform
platformio platform uninstall teensy

# uninstall existing PlatformIO
pip uninstall platformio

# install the latest development version
pip install -U https://github.com/platformio/platformio/archive/develop.zip

# install teensy from development branch
platformio platform install https://github.com/platformio/platform-teensy/archive/develop.zip
