Title Undefined

[ngooide]

Does anyone know how to solve this problem?
Thank you.

I think this is usually down to loading the fullcalendar library twice.

BrockReece,
Thanks for the reply.
Hmm... weird.. if the library loaded twice, I'm guess it will shows up on the resource... btw, what other chances that this will happen?

[BrockReece]

It looks like you have jQuery loading twice?

[ngooide]

No luck...
Even remove jquery.

Have you seen this thread?
fullcalendar/fullcalendar#3911 (comment)

[ngooide]

Yup seen this before. but it doesn't work for me. Hope my code is correct.

<template>
    <full-calendar :config="config" :event="events"/>
</template>

<script>

    // import FullCalendar from "vue-full-calendar";

    import FullCalendar from "fullcalendar-scheduler";
    import "fullcalendar/dist/fullcalendar.min.css";
    import "fullcalendar-scheduler/dist/scheduler.min.css";

    Vue.use(FullCalendar);

    import moment from "moment";
    export default {
   ...

[ngooide]

Finally I got it right.
But I think this is not the right way of doing it.
Could anyone pls assist me on the right way of doing it?

If you have directly edited the node_modules dir, the changes will not be properly persisted.
My guess is that your versions of vue-full-calendar and fullcalendar-scheduler depend on different/incompatible versions of fullcalendar and thus is loading fullcalendar twice.

You can use commands like...

npm ls fullcalendar
// or
yarn list fullcalendar

To list the different versions you have loaded in your project.
As an example, here is me searching my project for the node-fetch package

yarn list node-fetch
yarn list v1.12.3

Yea you are right. These component r using different version of fullcalendar.

But the version reference
From vue-full-calendar@2.5.2 (fullcalendar@3.10.0) to vue-full-calendar@2.7.0 (fullcalendar@3.9.0)

It still show "undefined..." even there is only 1 version.

Apology that I'm still learning.

[ngooide]

This is what I've tested & it works properly.

1. node_modules/vue-full-calendar,

// import 'fullcalendar'

2. my own file "vue-calendar.vue", I add in this

 import 'fullcalendar'

3. my own file "vue-scheduler.vue",

import FullCalendar from "vue-full-calendar";
// import 'fullcalendar'
import "fullcalendar-scheduler";

If I unmark "import 'fullcalendar'", "undefined" will appear.
