installing PyQt5 error on docker image creation

Error installing PyQt5 on building of the docker image

When docker is creating the image, the RUN python3.7 -m pip install -r requirements.txt step fails trying to install PyQt5.

Browsing for possible solutions, I came across with this stack overflow answer and set the version of PyQt5 at 5.14 in requirements.txt file
PyQt5==5.14 instead of PyQt5>=5.14

According to the answer, there is probably a bug in PyQt5 to Pypi.

Reproduce the issue
Steps to reproduce the behavior:

1. checkout to dev branch
2. docker build -t "wifipumpink3" .
3. The following error appears:

Collecting PyQt5>=5.14 (from -r requirements.txt (line 12))

    FileNotFoundError: [Errno 2] No such file or directory: '/tmp/pip-build-ewyvq7f6/PyQt5/setup.py'

Expected behavior
The docker image should be created without any problems

• Wifipumpkin3 version: 8b06498
• Virtual Machine (yes or no and which): No
• Operating System: Ubuntu 20.04

I had a problem with pyqt5 on docker and really only working fine the version 5.14. I 'm try to find a solution for this, maybe create another requirements.txt for only docker image. btw, this is a bug of pyqt did you say to me.

Thanks @mh4x0f for your work,
I had another issue with the requirements.txt once the docker image was created, this time with the scapy version. However this happened when I was trying to run the container and after that I had yet another error with python. Should I describe the problem I had here or should I file another issue?

describe here if the bug is only with docker

This error happens with out docker too
It is not wifipumkin related its pyqt5
You can install it with
sudo apt-get install python3-pyqt5
and just remove it from requirements.txt

Hi @mh4x0f, the other issues I had was because I was wrongly running the docker container, so there is no problem with the current scappy version after all.

@rafonsecad thank's for report, I add a fix to install the version 5.14 on docker build image

Hello guys,

I had this issue yesterday during the installation. Both inside and outside docker.
I am running this on a raspberry, and applying this fixed the issue for the "regular setup".

However I do not understand why I am experiencing this during the docker build on my raspberry, does any one have an idea?

[rafonsecad]

Hi @bobafouette,

Yes, I ran into the same issue, and I use the same fix with a normal installation. As far as I understand, raspberry runs on a different architecture(ARM) and for that reason the pyqt5 package docker was trying to install in the raspberry is not the same that the package you find in a x86 architecture.
Since using apt to install pyqt5 works, my guess is that the pyqt5 ARM package you get from pip is broken, so you could make a test and change the dockerfile to install pyqt5 from apt and not from pip and see if it works.

Happy to see I am not the only one, and your point on the architecture totally makes sense.
I will definitely try this fix on the docker install and post the results for anyone interested.
It might be a little bit off topic but, my understanding of docker Dockerfile's purpose is it's supposed to be "idempotent". To me the arch my build is running on should not impact the outcome of the process.
If we agree on this, maybe this issue could be reopened so we can find a way to make the docker setup work on rapsberry as well?
