If you upgraded from before rc1, you need to update your angular.json file

Rc1 breaking changes

  "projects": {
    "app": {
      "architect": {
        "build": {
          "options": {
            "assets": [
                "glob": "**/*",
                "input": "src/assets",
                "output": "assets"
               "glob": "**/*.svg",
               "input": "node_modules/ionicons/dist/ionicons/svg",
              "output": "./svg"

Rc1 icon breaking changes

after adding it ion-icon is working. But now the problem is that ion-icon is not working when used inside a icon only button

Can you post the problematic code?

              <ion-button color="primary" shape="round" fill="outline" size="small" [routerDirection]="'forward'" [routerLink]="['/admin-product-form',]">
                  <ion-icon slot="icon-only" name="paper"></ion-icon>
                <ion-button color="danger" shape="round" fill="outline" size="small" (click)="remove(">
                    <ion-icon slot="icon-only" name="trash"></ion-icon>

try removing the slot="icon-only" and see if that affects your UI

Still it’s not working. ‘ion-icon’ is not working within button. I have updated the angular.json file and also i have updated the latest ionic 4 version 4.0.0
