I'm seeing the same issue. It is probably related to the warning that appears when running ionic serve:

warning  in ./node_modules/@ionic/vue/dist/ionic-vue.esm.js
"export 'ICON_PATHS' was not found in 'ionicons/icons'

Same here. Cant serve freshly created app.

the work around i found is to first install

npm install @ionic/core@one 
npm install @ionic/[email protected]

modify the main.js file

import Vue from "vue";
import App from "./App.vue";
import router from "./router";
import store from "./store";
//import Ionic from "@ionic/vue"; // comment this line 
import { defineCustomElements as ionic } from "@ionic/core/loader"; // add a direct link to @ionic/core
import { defineCustomElements as svgmorphing } from "stencil-svgpaths-morphing/dist/loader";

import "@ionic/core/css/ionic.bundle.css";

//Vue.config.ignoredElements = [/jeep-\w*/]; // comment this line
Vue.config.ignoredElements = [/^ion-/, /^jeep-/];   // add this line

//Vue.use(Ionic);  // comment this line
ionic(window); // add this line
svgmorphing(window);

Vue.config.productionTip = false;

new Vue({
  router,
  store,
  render: h => h(App)
}).$mount("#app");

and keep the file router.js as it is meaning still using the IonicVueRouter

and it works fine.
Now if you look at package-lock.json ,

@ionic/core is version "4.6.0-dev.201906131724.645b9a9" requiring "ionicons": "4.5.9-1"
@ionic/vue is version 0.0.4 with dependencies @ionic/[email protected] requiring "ionicons": "4.5.10-2

In fact to see the icons the main.js should be :

import Vue from "vue";
import App from "./App.vue";
import router from "./router";
import store from "./store";
import { defineCustomElements as ionic } from "@ionic/core/loader"; // added line
import { defineCustomElements as svgmorphing } from "stencil-svgpaths-morphing/dist/loader";

//import Ionic from "@ionic/vue"; // commented line
import { addIcons } from "ionicons"; // added line
import { ICON_PATHS } from "ionicons/icons"; // added line
import "@ionic/core/css/ionic.bundle.css";

//Vue.config.ignoredElements = [/jeep-\w*/];  // commented line
Vue.config.ignoredElements = [/^ion-/, /^jeep-/]; // added line

//Vue.use(Ionic); // commented line
ionic(window); // added line
svgmorphing(window);
addIcons(ICON_PATHS); // added line
Vue.config.productionTip = false;

new Vue({
  router,
  store,
  render: h => h(App)
}).$mount("#app");

Now the icons are displayed
This can be use as workaround till @ionic/vue is updated to @ionic/core@one

I'm facing the same issue. Cant serve freshly created app.

Same here

Temporarily,

• common anything related to Icons in these file (ionic-vue.esm.js, chunk file that's show in console)

I did this, and app worked for me but that's not the right solution, but you can do this now to can continue your work

if you can't find these file go to project directory and from computer/lap search right the first name of file. (if you search for ionic-vue.esm.js write -> ionic and will appear all files/folders started with ionic then choose the file you're looking for in this case (you should choose ionic-vue.esm.js ).

Abdlrahmansaber's temp-fix works,
(He means "Comment" not "Common") You want to comment out the lines he commented out in his screenshots.

Thank you Adrianmed :)

probably I know the reason of this bug

the reason because if you trying to import the {ICON_PATH} it's return nothing, try to print it in console it will return nothing.

@Adrianmed @Abdlrahmansaber yes it works but kill the icons so this is not a temporary solution for a released app :)

I've applied the solution of @Abdlrahmansaber. But it's not working properly (the compile warning and console error disapeared).
I'm trying to follow that: https://ionicframework.com/blog/announcing-the-ionic-vue-beta/
But in the moment I add

import Ionic from '@ionic/vue';
import '@ionic/core/css/ionic.bundle.css';

Vue.use(Ionic);

to main.js all I get is a "blank" page.

Current dependencies versions:
"dependencies": {
"@ionic/vue": "0.0.4",
"vue": "^2.6.10",
"vue-router": "^3.0.3"
},
"devDependencies": {
"@vue/cli-service": "^3.8.0",
"vue-template-compiler": "^2.6.10"
}

edit: It works fine to me, even with your quoted import

You should use the one I suggested two days ago it works and you see the icons

@wannymiarelli I know it's killed the icon but you can develop whole app without icon until fix the bug

and you're right it's not solution for released app

@mbilbao can you show me the console ?

I get this resolved by changing ionicons version in package-lock.json

But it should be work with fresh npm install in fact

@mbilbao can you show me the console ?

Hey, the console was clear, without any error, warnings or whatever shows when you check verbose mode.
I already downgraded the ionicons package as @daarioautumn posted and it works.
Thank you @Abdlrahmansaber anyway.

Just add [email protected] to your package.json. This just overrides any peer dependency and can be used as a workaround.

@mbilbao I have the same issue. Did you find a fix?

I have the same issue. I looked couple hours on internet to find a solution but I didn't find a proper way to resolve this problem. Can someone help me?

@mbilbao I have the same issue. Did you find a fix?

Yes, I applied the solution of @daarioautumn just downgrade the ionicons package to 4.5.8

@yasin-mesut solution works for me

Just install the ionic package: npm install [email protected] --save-dev as @yasin-mesut suggested

@jepiqueau your workaround worked for me but now I have content added to the end of every ion-item in my app:

Have you encountered this issue? Do you know how to solve it?

I just moved to normal Ionic with Angular. But I still want to develope my project with vue framework sad

Yes, I applied the solution of @daarioautumn just downgrade the ionicons package to 4.5.8

I found this style:

html:not(.hydrated) body {
    display: none;
}

this is solve in using @ionic/[email protected]. so i close the issue

Could publish the latest version (@ionic/[email protected] ) to npm? now in npm is v0.0.4.

It is published on npm do npm install --save @ionic/vue@next

@jepiqueau's solution worked perfectly for me. Thank you!!!

It works fine in @ionic/[email protected] but only with the ions added in vue appInitialize, ie:
close, reorder, menu, arrow-forward, arrow-back, arrow-down, search & close-circle.

When can we hope to have the full access to all icons?

Of course one can edit ionic-vue.esm.js but not sure this is the recommended way....

the solution for having other icons is to add them in the main.js file ie for icons "star","trash","create" you do this

// after import Ionic from "@ionic/vue"; 

import { addIcons } from "ionicons";
import { star, trash, create } from "ionicons/icons";

// after Vue.use(Ionic);
addIcons({
  "ios-star": star.ios,
  "md-star": star.md,
  "ios-trash": trash.ios,
  "md-trash": trash.md,
  "ios-create": create.ios,
  "md-create": create.md
});

that's it and it works so do it for any icons you want to use even for the one you want to add in a ion-item
hope it's help

Have a look at branch ionicone of
https://github.com/jepiqueau/vue-test-stencil-svgpaths-morphing
i add a TestIcons button in Home.Vue and a TestIcons.Vue showing the desired icons

It works fine. Thanks for the help. Is it a temporary fix or is the way forward to access icons?

I do not know the plans of the Ionic team but for me it is logical to import only the icons you need in your app instead of all the icons which will increase the size of your app for no value

Note, when trying to import icons with dashes in the name, for example log-out you can use logOut in the import instead.

import { addIcons } from "ionicons";
import { logOut } from "ionicons/icons";
addIcons({
  "ios-log-out": logOut.ios,
  "md-log-out": logOut.md
});

that's the way

Has this been resolved?

For people running into this in the future, the fix is somewhat buried above. Just update your version of @ionic/vue, eg:

$ npm install @ionic/[email protected]

@hunterloftis - thanks. That did it. I hope it gets officially updated before I go to prod, but it works for now.

Thanks guys, you really made it easy for me
