Spyder won't install correctly in coastsat env

[JuliaS343]

Hi! I am currently trying to install the coastsat environment on another laptop with spyder included. I used this code in the Miniforge prompt:

mamba create -n coastsat
mamba activate coastsat
mamba install python=3.11 geopandas gdal -y
mamba install earthengine-api scikit-image matplotlib astropy notebook -y
pip install pyqt5 imageio-ffmpeg
mamba install pyfes -y
mamba install -c conda-forge spyder

In the last line I added spyder. However, when I try to launch spyder with the miniforge prompt I get: This application failed to start because no Qt platform plugin could be initialized. Do you know how I can resolve this issue?

yes that is a common issue, there's an easy fix for that, please google it. It is something like running another pip install pyqt command with the right version

Thank you for your suggestion. I tried to google it, but I could not really find a definite solution. I tried installing another version of pyqt5 but that did not work. Do you maybe have any other suggestions?

try to install all these with pip:
PyQt5 5.15.11
PyQt5-Qt5 5.15.2
PyQt5_sip 12.15.0
PyQtWebEngine 5.15.7
PyQtWebEngine-Qt5 5.15.2
and Spyder 6.0

Thank you for your reply. For the moment I found a kind of workaround with Spyder and CoastSat. When I have time I will try this. Do you also recommend installing Spyder with Pip?
