"Error: No provider for Overlay!"
Solution 1
I managed to eliminate this error by adding this to app.module.js:
import {OVERLAY_PROVIDERS} from "@angular/material";
@NgModule({
imports: [...
],
declarations: [...],
providers: [OVERLAY_PROVIDERS],
bootstrap: [...]
})
Edit (May 2018):
OVERLAY_PROVIDERS is now deprecated. use the OverlayModule instead
import { OverlayModule } from '@angular/cdk/overlay';
@NgModule({
imports: [
OverlayModule
],
declarations: [...],
providers: [...],
bootstrap: [...]
})
Solution 2
You should do MaterialModule.forRoot()
(see the UPDATE2) that should fix the issue.
FYI That is the base maerial2 setup:
import { MaterialModule, MdIconRegistry, } from '@angular/material';
@NgModule({
declarations: [
AppComponent
],
imports: [
BrowserModule,
FormsModule,
HttpModule,
MaterialModule.forRoot()
],
providers: [MdIconRegistry],
bootstrap: [AppComponent]
})
export class AppModule { }
See more details here http://iterity.io/2016/10/01/angular/getting-started-with-angular-material-2/
UPDATE1: The official material2 doc has being updated so you might look in to this as well https://material.angular.io/guide/getting-started
UPDATE2: In the latest material2 (from 2.0.0-beta.2 and up) no need to use MaterialModule.forRoot()
any more just use MaterialModule
instead.
The use of Module forRoot has been deprecated and will be removed in the next release. Instead, just simply import MaterialModule directly:
@NgModule({
imports: [
...
MaterialModule,
...
]
...
});
UPFATE3: Starting from version 2.0.0-beta.8
angular material depends on @angular/cdk
so you need npm install that as well.
Solution 3
For @angular/material
version 6 and beyond: import OverlayModule
in your root module (e.g. in app.module.ts
). Importing in lazy-loaded module doesn't work! Details: https://github.com/angular/material2/issues/10820#issuecomment-386733368
Solution 4
MdTooltipModule.forRoot()
should also solve your problem as it also includes providers: [OVERLAY_PROVIDERS]
.
This is from source:
export class MdTooltipModule {
static forRoot(): ModuleWithProviders {
return {
ngModule: MdTooltipModule,
providers: OVERLAY_PROVIDERS,
};
}
}
Solution 5
I solved this issue by importing my own MaterialModule, which looks something like this
import { NgModule } from '@angular/core';
import {
MdButtonModule,
MdCardModule,
...
} from '@angular/material';
@NgModule({
imports: [
MdButtonModule,
MdCardModule,
...
],
exports: [
MdButtonModule,
MdCardModule,
...
]
})
export class MaterialModule {}
into the spec file, like so
import { MaterialModule } from 'app/material/material.module';
TestBed.configureTestingModule({
imports: [MaterialModule],
...
});

Any ideas what this is all about?
