树莓派3B使用Python+pygogo日志报错：No module named builtins

Hey Vikram, let's get this pygogo error sorted out for you. That No module named builtins message is almost always tied to a Python version mismatch—here's why and how to fix it:

Why This Happens #

Raspberry Pi 3B typically comes with both Python 2 and Python 3 pre-installed. The builtins module is a Python 3-only built-in module—Python 2 uses __builtin__ (with double underscores) instead. Since pygogo is designed for Python 3+, if you're running your script with Python 2, it'll throw this exact error.

Step-by-Step Fixes #

• Check your default Python version
  Run these commands in your terminal to confirm which versions you're working with:

  python --version
  python3 --version
  

  If python --version shows Python 2.x, that's the root cause.

• Run your script with Python 3
  Instead of using python your_log_script.py, use the Python 3 interpreter explicitly:

  python3 your_log_script.py
  

• Ensure pygogo is installed for Python 3
  If you originally installed pygogo with pip install pygogo, it probably got installed to your Python 2 environment. Install it for Python 3 instead:

  # First install pip3 if you don't have it
  sudo apt-get update && sudo apt-get install python3-pip -y
  # Then install pygogo for Python 3
  pip3 install pygogo
  

Bonus: Set Python 3 as your default (optional) #

If you want to avoid this confusion in the future, you can set Python 3 as your default python command:

sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 1

That should resolve the builtins module error and get your pygogo logging up and running on the Pi 3B.
