Problem Description

Installing v4 beta5 gives errors, then Spyder throws PyQt5.QtWebKitWidgets "ModuleNotFoundError:

What steps reproduce the problem?

1. I ran conda update qt pyqt to update qt and pyqt to make sure those were current. I did not have any error messages.
2. I ran conda install -c spyder-ide spyder=4.0.0b5 and then I got :

The program Spyder v4.0.0b5 was installed in Anaconda Navigator okay (it appears in the Navigator.)

3. Then I ran `spyder` from the Anaconda Command Prompt (with Admin privileges) and by clicking the "Launch" icon in Navigator.

### What is the expected output? What do you see instead?

I expected Spyder to start up without error from both the command line and by clicking the Anaconda Navigator icon.

But instead I got the following from the Anaconda Command Prompt when I try to start Spyder with the command >>`spyder` at the command prompt, or from Anaconda Navigator by selecting it from Anaconda Navigator

During handling of the above exception, another exception occurred:

I've tried updating qt and pyqt separately  but still get this issue.  I am doing all of this in a virtual environment named quantecon.  

[ccordoba12]

nstalling Spyder 4.0.0b5 gives error about DEBUG menuinst_win32:init(199)

This is not an error, it's only a debug message, so you can safely ignore it.

The real problem is that you broke your Anaconda installation by using pip to install PyQt5 (as you mentioned on issue #8952), so now you have to reinstall it.
