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.
