I am trying to import an npm package into my vue.js component. Specifically, I am trying to import ScrollMagic into my project, but I am getting it to be undefined.
I have seen people suggest previously that it should be in my mounted() hook, which I am doing but my import statements (I have tried both in main.js, and in the components tag but both have returned undefined variables. Any direction would be appreciated.
Script for my component:
<script>
import { ScrollMagic } from 'scrollmagic';
export default {
name: 'Scroller',
mounted() {
console.log(ScrollMagic);
},
};
</script>
And in my main.js
import Vue from 'vue';
/*
IMPORT STATEMENTS FOR MODULES GO HERE
*/
import sm from 'scrollmagic';
import gsap from 'gsap';
import App from './App.vue';
import './registerServiceWorker';
import router from './router';
Vue.config.productionTip = false;
/*
Usage statement
*/
Vue.use(sm);
Vue.use(gsap);
new Vue({
router,
render: (h) => h(App),
}).$mount('#app');
Maybe the scrollmagic package doesn't export a variable or function ScrollMagic, so it keeps getting undefined?
Have you tried:
import * as ScrollMagic from 'scrollmagic';
// OR
import ScrollMagic from 'scrollmagic';

Hi i have a situation something like this
I have 2 files
main.js
utils.js
main.js
import { createApp } from 'vue'
import Utils from "./utils.js"
import router from "...."
import VueCookies from 'vue-cookies'
const app = createApp(App);
app.use(router);
app.use(VueCookies)
app.use(Toast,Utils.toastConfig())
app.mount('#app')
utils.js
import Vue from 'vue'
export default{
setCookie(params){
Vue.$cookies.set(params.name, params.value)
}
...
// so on related to Vue.$cookies
}
Note: above file usage is in multiple places, changing everywhere is not feasible now as we are migrated from vue2 to vue3
Question: Vue is undefined in utils.js how to make it work without much code changes
I don't know how to solve this problem.
When I started project vue3.js , console show me this error.
This import in pinia store.
I tryied change first line with import to
"import Vue from 'vue';" (without curcy braces), but error don't disappear.
import { Vue } from 'vue';
import { defineStore } from 'pinia';
import moment from 'moment';
import _ from 'lodash';
import router from '#/router';
if you are using latest version of vue , vue3
this code
import { Vue } from 'vue';
is no longer global instance
I recently ran an npm update on my Vue/Laravel app just to upgrade my version of Bulma. Of course, this brought up a dozen vulnerabilities which I decided to fix, and of course this screwed up my whole app, mainly thanks to Webpack and Mix issues. I finally got it everything to compile again with only a few SASS warnings, but when I run the app I get the following error:
Uncaught TypeError: Vue.use is not a function
Google seems to suggest this is a problem when upgrading to Vue 3, however I am still on Vue 2 (2.6). Here's my app.js:
require('./bootstrap');
import VueRouter from 'vue-router';
import router from './router/routes';
import VueConfirmDialog from 'vue-confirm-dialog'
import SkeletonBox from './components/shared/SkeletonBox.vue'
import ValidationErrors from './components/shared/ValidationErrorComponent.vue'
import Vuex from 'vuex';
import storeDefinition from './store'
import Index from './Index'
window.Vue = require('vue');
Vue.use(VueConfirmDialog);
// init the Router
Vue.use(VueRouter);
// Init the Vuex store
Vue.use(Vuex);
const store = new Vuex.Store(storeDefinition);
Vue.component("skeleton-box", SkeletonBox)
Vue.component("v-errors", ValidationErrors)
const app = new Vue({
el: '#app',
router,
store,
publicPath: './',
components:{
"index": Index
},
beforeCreate(){
// call loadStoredState action in store.js
this.$store.dispatch('loadStoredState');
}
});
I have absolutely no idea what I need to do to get this working - can anyone help?
I seem to not be able to use axios in my vue project as it's saying that 'axios' is not defined when I try using axios.get() in my file for Home.vue. Am I doing something wrong in main.js where I configure it? Or am I missing something that needs to be added? Below is my code for main.js and it shows how I'm adding axios to my project.
import Vue from 'vue';
import GSignInButton from 'vue-google-signin-button';
import ElementUI from 'element-ui';
import axios from 'axios';
import './assets/element-variables.scss';
import locale from 'element-ui/lib/locale/lang/en';
import App from './App.vue';
import router from './router';
import store from './store';
Vue.config.productionTip = false;
Vue.use(ElementUI, { locale });
Vue.use(GSignInButton);
Vue.use(axios);
Vue.use(ElementUI);
new Vue({
router,
store,
render: (h) => h(App),
}).$mount('#app');
Edit: The solution for this issue for me was to install a vue plugin called vue-axios and follow the steps to configure here: https://www.npmjs.com/package/vue-axios
Try to add axios as instance global property instead of Vue.use(axios);:
Vue.prototype.$axios=axios
then you could use it in any child component like this.$axios.get()

I try using Vue 3, but I look can't using Vue.use(exampleplugin) again.
I using command vue add bootstrap-vue after generate vue create project. And on plugin bootstrap-vue warning with code:
import Vue from "vue";
import BootstrapVue from "bootstrap-vue";
import "bootstrap/dist/css/bootstrap.min.css";
import "bootstrap-vue/dist/bootstrap-vue.css";
Vue.use(BootstrapVue);
Output warning terminal:
warning in ./src/plugins/bootstrap-vue.js
"export 'default' (imported as 'Vue') was not found in 'vue'
warning in ./node_modules/bootstrap-vue/esm/utils/vue.js
"export 'default' (imported as 'Vue') was not found in 'vue'
What's wrong with that? And how do I use vue 3 to add plugin bootstrap-vue?
Bootstrap Vue is not yet ready for Vue 3.
To answer part of your question, Vue 3 changes the method for instantiating the application instance, including how plugins are registered.
For example...
import { createApp } from 'vue';
import Router from './router/Router';
createApp({/* options */}})
.use(Router)
.mount('#app');
You can read more about this at the official docs.
https://v3.vuejs.org/guide/instance.html
https://v3-migration.vuejs.org
For vue 3 you can use
bootstrap-vue-3
Install: npm i bootstrap-vue-3
Config:
import { createApp } from "vue";
import App from "./App.vue";
import BootstrapVue3 from "bootstrap-vue-3";
import "bootstrap/dist/css/bootstrap.css";
import "bootstrap-vue-3/dist/bootstrap-vue-3.css";
const app = createApp(App);
app.use(BootstrapVue3);
app.mount("#app");
