Unknown option -D Gjs

Gjs documentation says gjs -D -S example.js will start a debugger but when I do the same follow error occurs

$ gjs -D test.js

(gjs:26381): Gjs-ERROR **: 06:18:06.759: option parsing failed: Unknown option -D
Trace/breakpoint trap (core dumped)

I am using Ubuntu 18.10 with gnome 3.28.2 and Gjs 1.52.5.

Solution

  • The new debugger is only available in gjs >= 1.53.90 or the stable release 1.54.0 shipped with GNOME 3.30.

    For a detailed list of when features are shipped and in what version, see https://gitlab.gnome.org/GNOME/gjs/blob/master/NEWS.
