Gantt is undefined

[lfk0719]

import {gantt,Gantt} from "dhtmlx-gantt";
I use it in vue2. I want to use the method gantt.getganttinstance (). The installed version is 7.1.4, but Gantt is undefined

@lfk0719,
You need to call the getGanttInstance method from the Gantt object, note the capital G:

Gantt.getGanttInstance()

https://docs.dhtmlx.com/gantt/desktop__multiple_gantts.html

There is a demo for Vue.js, but it uses the 3.x versions:

However, in the past, there was the 2.x version:

I tried to reproduce the issue with the getGanttInstance method, but it is working correctly.
Here is the demo:

If that doesn't help you, please send me a ready demo with all the necessary files so that I can reproduce the issue locally.
