Viewrendered not loading using Python 3.5.1 64-bit and PyQt 5.6.0 on Windows 10 64-bit

[Dee]

Hi,

I just installed Leo on my Windows 10 64-bit computer, but it won't load viewrendered.

I installed Leo following the recommended installation instructions.

First I installed:

Python 3.5.1 64-bit

PyQt 5.6.0

Git 2.8.4 64-bit

Then I used the following command in Git Bash to install the latest version of Leo:

git clone https://github.com/leo-editor/leo-editor

which installed it here:

C:\Users\Dee\leo-editor

To run Leo, I run launchLeo.py from the above directory.

Here's the log when I first run Leo:

Leo Log Window

Leo 5.4-devel, build 20160412153848, Tue Apr 12 15:38:48 CDT 2016

Git repo info: branch = master, commit = 09002eae17d0

Python 3.5.1, PyQt version 5.6.0

Windows 10 AMD64 (build 10.0.10586) SP0

leoID=Dee (in C:\Users\Dee\.leo)

load dir: C:\Users\Dee\leo-editor\leo\core

global config dir: C:\Users\Dee\leo-editor\leo\config

home dir: C:\Users\Dee

reading settings in C:\Users\Dee\leo-editor\leo\config\leoSettings.leo

Using default leo file name:

C:\Users\Dee\.leo\workbook.leo

loadOnePlugin: can not load enabled plugin: leo.plugins.viewrendered

reading settings in C:\Users\Dee\leo-editor\leo\doc\CheatSheet.leo

Then if I attempt to open the viewrendered pane, the log gives the following errors:

exception executing command

Traceback (most recent call last):

  File "C:\Users\Dee\leo-editor\leo\core\leoCommands.py", line 5348, in doCommand

    self.html_class = QtWebKitWidgets.QWebView

AttributeError: 'NoneType' object has no attribute 'QWebView'

Note: Prior to installing Leo as described above, I downloaded and briefly tried out the "Quick Install" version, which uses PyQt version 4.8.7, and it worked fine.

I am very intrigued by Leo, so I'd be grateful for any assistance to get it working. :)

There has been considerable work on the vr and vr2 plugins lately.  They should both work with the latest revs, or explain why not.

In particular, vr2 is known not to work with PyQt5.  This is due to significant changes in the QWebView class.
