Unfortunately, there’s still something very wrong with this Anaconda installation, it failed to install Spyder, complaining about QtWebEngineWidgets.py not being there, but qt is installed when checked with conda list.
Upon trying conda install PyQtWebEngine, the resolver just sat there for hours not finding any way forward.
Many people suggest using pip to install it, but many people condemn the use of pip with anaconda. There doesn’t seem to be any official info on what to do.
On Windows the installer just works, but on Mac M2 this is not the case.
