Problems trying to run LeoWapp

[Xavier G. Domingo (xgid)]

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):

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):

Did you 'pip install flexx' ?

Never mind, I am seeing similar problems on my Linux machine.

I'll attempt a fix today.

Recent revs allow me to run leoflexx.py in standalone mode in Ubuntu.  The following works, provided that you start from the leo-editor directory:

python leo/plugins/leoflexx.py

On Ubuntu, problems remain when attempting to run:

leo --gui=browser

The connection between LeoWapp and the server seems to break immediately. This is mysterious. For now, the workaround on Linux is to run leoflexx in stand-alone mode.

Great! After switching to the latest skeleton commit from this morning (Commit hash: 324649a689927aee0b847bf7a16f2d7285c53aed), it's working for me with the usual:

python launchLeo.py --gui=browser

Now playing with the new GUI. I like it!!

Thanks for the report.  Recent revs allow you to specify a list of files to load.  However, only the first one is actually shown.
