RPi PyQt5

Published on 12 Dec 2020

I have been wanting to build an actual dashboard for the SMRT CLK project but never have gotten around to it. I decided to start working on the dashboard recently and wanted to build it in Python with PyQt. The first step is obviously to install PyQt which caused me some problems on the Pi. I decided to use PyQt5 since it is more current and compatible with Python 3+. It was simple enough to install on my Mac using Anaconda but I had issues installing it on the Pi with pip3. I would get the following error:

$ pip3 install PyQt5
Complete output from command python setup.py egg_info:
    Traceback (most recent call last):
      File "<string>", line 1, in <module>
      File "/usr/lib/python3.7/tokenize.py", line 447, in open
        buffer = _builtin_open(filename, 'rb')
    FileNotFoundError: [Errno 2] No such file or directory: '/tmp/pip-install-l9pwfk8o/PyQt5/setup.py'
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-l9pwfk8o/PyQt5/

After spending some time on Google I found a thread on the Raspberry Pi forum discussing the issue. The install command that I finally got to work is shown below.

$ sudo apt-get install qt5-default pyqt5-dev pyqt5-dev-tools

I can now prototype the dashboard on my Mac and also run it on the Raspberry Pi in my SMRT CLK.
