Today I've updated Leo to the latest current devel version in GitHub:
Leo 5.8.1 devel, build 20181204214531, Tue Dec 4 21:45:31 PST 2018
Git repo info: branch = devel, commit = 09f59c3537f8
Python 3.6.2, PyQt version 5.6.2
Windows 10 AMD64 (build 10.0.17134) SP0
... and then tried to run the browser GUI version with the command:
python launchLeo.py --gui=browser
But it produced the following error message (in a popup):
[image: LeoWapp_Webruntime_error_message.png]
Any advice will be much appreciated. Tell me if you prefer that I create a
GitHub issue for this.
This is the whole error log (ignore the reference to "Leo-5.4" appearing in
the path, it *is* in fact the current devel version):
[I 22:52:04 flexx.app] Asset store collected 2 new modules.
