[Paraview-developers] Development on Light-Viz

[Albrecht Kyrieleis]

Hi,
I want to customize Light-Viz (under Linux CentOS 7) and started to go
through the steps on the developments page but ran into a few problems.

1) I want to add a new functionality including a new 'button' for
Light-Viz. So I think I would amend the scripts in dir lib adn server and
then do a npm run build:release to produce content in dir distro which is
seen by the webserver. Is that right ?

1)  running git clone git at github.com:kitware/light-viz.git  results in an
unresponsive (for about 10mins) terminal saying 'cloning into 'light-viz''.
2) I have previously just installed light-viz using   npm install -g
light-viz    which worked fine. But running npm run build results in the
following error:

Thank you very much for any help
