I am trying to run a package on my Raspberry Pi:

At the terminal, I typed in “sudo apt-get install picap” followed by enter.

I get it installed but cannot execute "picap-setup" – instead an error message follows:

pi@raspberrypi:~ $ picap-setup Traceback (most recent call last): File "", line 1, in ImportError: No module named RPi

Python-dev and Rpi.GPIO are installed on the Pi. I also updated the Pi with the latest version with sudo apt-get update and sudo apt-get dist-upgrade.

Picap comes from : https://www.bareconductive.com/make/setting-up-pi-cap-raspberry-pi/

I am thankful for any hints.

First of all, repeat following process

sudo apt-get install python-pip
pip freeze | grep RPi

see what you get after this second command, If you get a valid module for RPi.GPIO or not. And then following if not installed.

For Python 2

sudo apt-get install python-dev python-rpi.gpio

or

pip install RPi.GPIO

For python3

sudo apt-get install python3-dev python3-rpi.gpio

and then ( for python 2 or python 3):

sudo apt-get install picap
picap-setup

These all worked for me, Just you need to verify pip freeze | grep RPi. And one more thing sometimes some modules are not available for normal user only for root user. Make sure. I did all above using my pi user.

If Python RPi module is missing, one can install pip with all dependencies and then install the module using pip or go with the better approach and install the module alone:

sudo apt-get install python-rpi.gpio

for Python3 this one:

sudo apt-get install python3-rpi.gpio

or

I had a similar issue with my Pi. Doing a simple pip install solved the issue.

pip install RPi.GPIO

if using pycharm on windows then it will work like this

  1. upgrade pip

    C:\Users\sandeep\PycharmProjects\newnum1\venv\Scripts\python.exe -m pip install --upgrade pip

  2. installing the module

    pip install RPi.GPIO

  3. it worked for me should work for everyone
