I'm working on a simple angular project where I am trying to import Material Design into my project but some of the components aren't working properly and a console warning says:
Could not find HammerJS. Certain Angular Material components may not work correctly.
I have hammerjs
installed and also @angular/material
. How do I resolve this issue?
It may be worth noting that if you have hammerjs
installed and your components are still not rendering correctly to make sure you are using angular material
components and not html elements with materialize-css
classes.
If you are using materialize-css
instead of angular material
, you will need to add it to your project separately.
In your package.json
file add this to dependencies
"hammerjs": "^2.0.8",
Or if you want an alternative automatic way just you can type npm i hammerjs --save
(or npm i [email protected] --save
if you want, since 2.0.8
is the latest version nowdays) in your root project folder and test then, if the problem still occurring try to delete the node_modules
folder and reinstall it in the root project folder also by running npm install
which will check the dependencies
(where hammerjs
resides), devDependencies
..., in package.json
file and install them.
Also in your polyfills.ts
(recommended to have a one if you have not)
import 'hammerjs/hammer';
Thus, it would be found while your angular app is executed since polyfills.ts
itself is called by import (in a normal case, else you can check it) in main.ts
which is the angular apps' entry point.
