Nemo-preview throws out JS error

  • 772

My system is Ubuntu 20.04, I download nemo-preview from the repository of Linux Mint and installed it manually. No error or warning shows in the installation. But nemo-preview does not function when I open nemo.

I run nemo-preview in the command line, and it shows the following information and then exit.

(nemo-preview-start:20719): Cjs-WARNING **: 14:03:55.707: JS ERROR: Error: Requiring NemoPreview, version none: Typelib file for namespace 'GtkSource', version '3.0' not found
@/usr/share/nemo-preview/js/ui/fallbackRenderer.js:31:7
@/usr/share/nemo-preview/js/ui/mimeHandler.js:28:7
@/usr/share/nemo-preview/js/viewers/image.js:38:7

Segmentation fault (core dumped)

And the content in /usr/share/nemo-preview/js/ui/fallbackRenderer.js:31:7 is

const NemoPreview = imports.gi.NemoPreview;

Does anyone know how to fix this problem?

    After installing gir1.2-gtksource-3.0 and other dependent packages, I finally solved this problem.
