How to fix the error “Could not find Angular Material core theme” in Angular 2?
You have to import a theme into your global css or sass file:
@import "~@angular/material/prebuilt-themes/indigo-pink.css";
or alternatively include it in your index.html
file:
<link href="node_modules/@angular/material/prebuilt-themes/indigo-pink.css" rel="stylesheet">
As in the theming documentation already mentioned Angular Material provides the following pre-built themes:
- deeppurple-amber.css
- indigo-pink.css
- pink-bluegrey.css
- purple-green.css
You have to include one of these themes or you create your own custom theme.
Adding @import to styles.css
doesn't work for me, adding theme to angular.json
did the trick
You can replace the default angular-material-theme with one of the above-mentioned angular-material-themes using the following ways.
You can directly include the pre-built angular-material-theme in the styles.css file.
@import '@angular/material/prebuilt-themes/deeppurple-amber.css';
Or Add the following inside the head tag of index.html file.
<link href="node_modules/@angular/material/prebuilt-themes/deeppurple-amber.css" rel="stylesheet">
Or Update the following in angular.json file.
"styles": [
{
"input": "node_modules/@angular/material/prebuilt-themes/deeppurple-amber.css"
},
"src/styles.css"
],
