2. Activate the environment, conda activate foqus-env
3. Manually install PyQt using conda, conda install pyqt
4. Clone the FOQUS repository, git clone https://github.com/CCSI-Toolset/FOQUS
5. Enter the new FOQUS directory, cd FOQUS
6. Go into the FOQUS folder to the file setup.py and comment out the PyQt5 package requirement
7. Go back to the Python console and run pip install -e .
