You should be able to activate the virtualenv using

. /path/to/your/virtualenv/bin/activate

And then use pip to update the software using

pip install - - upgrade pi-mqtt-gpio

However, unless you're using a Beaglebone there's no need to update to the latest code, as I was just adding support for that.

Awesome. Thanks for the quick response.

Another question Flyte. I've just set up a new pi with raspbian lite and am having a bit of trouble.

sudo supervisorctl status pi_mqtt_gpio

Reports that it is running but I'm not getting any mqtt messages published.

I had a look in the log and see a lot of:

ImportError: No module named RPi.GPIO
Last will set on 'gpio_bridge_1/status' as 'dead'.
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upg$

    return gpio_module.GPIO(gpio_config)
  File "/home/pi/ve/local/lib/python2.7/site-packages/pi_mqtt_gpio/modules/raspberrypi.$
    import RPi.GPIO as gpio

Which makes no sense to me. How can it not find RPi.GPIO if Requirement already satisfied: RPi.GPIO in /usr/lib/python2.7/dist-packages (0.6.5)

I tried sudo apt-get install python-dev python-rpi.gpio both in the venv and out but was informed that it was already installed.

Never mind this fixed it:


. mqtt_slave/bin/activate
pip install RPi.GPIO
