I have a similar Problem with QWebView and you seem to be the only one who wen't down the rabbit hole. Wanted to contact you but didn't see any contact details. Do you mind checking out: pyqt/python-qt5#57

Hi!

I hope I can help.

I noticed you used python 2.7. I would recommend maybe going for python 3 if possible as python 2 is no longer supported since this year. In case you have to use python 2, you might be interested in this appveyor script that I had working for python 2.7 with Qt 5.12 for a project :

• here the appveyor script : https://github.com/rllola/ZeronetBrowser/blob/01786c896ebe6c73000a085a2f170a06ad2b1d00/appveyor.yml
• The appveyor logs for this commit : https://ci.appveyor.com/project/rllola/zeronetbrowser/builds/23030035

I believe your are on windows ? You will have to install Qt 5.12 first.

Note: you will notice that in qt 5.12, PyQtWebEngine has been separated from PyQt project. It is an extra that need to be installed.

Regarding your specific problem with qtwebengine_locales I remember I had this too but I believe I fixed it using a qt.conf file (https://github.com/rllola/ZeronetBrowser/blob/01786c896ebe6c73000a085a2f170a06ad2b1d00/qt.conf). However it wasn't working for all the version of Qt... like 5.11 was a bit broken. And I don't think I tried anything prior to Qt 5.10

I also had this ugly hack where I would copy some files in my build but not sure if it is relevant (which I removed when going for Qt 5.12) :
rllola/ZeronetBrowser@01786c8#diff-180360612c6b8c4ed830919bbb4dd459L48-L49

Here this all the information I can give you and that I can remember... Sorry it is a bit messy. Maybe something will work for you.
