Hi,

I tried it again. This time I got an issue installing from your server. 
Using the command

~/environments/pyqt6env/bin/python3 -m pip install --index-url 
https://riverbankcomputing.com/pypi/simple/ --pre --upgrade 
--force-reinstall PyQt6 PyQt6-Qt6 PyQt6-Charts PyQt6-Charts-Qt6 
PyQt6-QScintilla

pip issues an error message and aborts.

==============================
INFO: pip is looking at multiple versions of pyqt6 to determine which 
version is compatible with other requirements. This could take a while.
ERROR: Cannot install PyQt6 and pyqt6-charts==6.2.0.dev2107131250 
because these package versions have conflicting dependencies.

The conflict is caused by:
     The user requested PyQt6
     pyqt6-charts 6.2.0.dev2107131250 depends on PyQt6>=6.2.0

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency 
conflict

ERROR: ResolutionImpossible: for help visit 
https://pip.pypa.io/en/latest/user_guide/#fixing-conflicting-dependencies
==============================

What did I do wrong? I am using pip version 21.1.3 (note that pip has a 
new dependency resolver as of version 20.3).
