Cannot find module 'ngx-bootstrap'

Question

I'm having an issue in my application with ngx-bootstrap whereby it now can't detect the module unless you specify the path

For example:

import { BsModalService, BsModalRef } from 'ngx-bootstrap';

produces " Cannot find module 'ngx-bootstrap' ".

Removing the reference and checking quickfixes just replaces the reference with:

import { BsModalService, BsModalRef} from 'ngx-bootstrap/modal/public_api';

Obviously this isn't ideal as they should be available through ngx-bootstrap without specifying the folder, and i would have to go through dozens of components and change these references which shouldn't be necessary. Has anyone had this problem before?

I've already tried:

• npm install
• npm update in case there were updates in recent commits
• Deleting node_modules folder and doing npm install again
• Re-installing ngx-bootstrap on its own - npm install ngx-bootstrap --save
• npm cache clean
• I've even started afresh and cloned my app into another location, run npm install , and the same thing happens

This was working fine yesterday. I'm not sure what I'm missing.

Answer 1

Based on ngx-bootstrap documentation , angular 9 doesn't support this kind of import. If you want to use BsModalService , ButtonsModule and so on you have to import them as below:

// RECOMMENDED
import { BsModalService, BsModalRef } from 'ngx-bootstrap/modal';
import { ButtonsModule } from 'ngx-bootstrap/buttons';

instead of:

// NOT RECOMMENDED
import { BsModalService, BsModalRef , ButtonsModule } from 'ngx-bootstrap';

Answer 2

As per https://github.com/valor-software/ngx-bootstrap/issues/5753

Updated documentation: https://valor-software.com/ngx-bootstrap/#/modals

 // RECOMMENDED
import { ModalModule } from 'ngx-bootstrap/modal';
// NOT RECOMMENDED (Angular 9 doesn't support this kind of import)
import { ModalModule } from 'ngx-bootstrap';

@NgModule({
  imports: [ModalModule.forRoot(),...]
})
export class AppModule(){}

This is the ideal solution as it is the one that is documented by the maintainer of the repo.

I had the same problem today, trying to update from Angular 9.0.2 to Angular 9.1.0 .

I guess it's because you have in your package.json : "ngx-bootstrap": "^5.3.2" , so npm is taking the latest version available on ngx-bootrap tag: 5.6.0 . (At least that's the version I have today)

I've solved just replacing the imports on my code, from 'ngx-bootstrap' to 'ngx-bootstrap/someBootstrapComponent' .

For example, my previous import was:

import { BsModalRef, BsModalService } from 'ngx-bootstrap';

And my new import looks like:

import { BsModalRef, BsModalService } from 'ngx-bootstrap/modal';

I know this is not an ideal solution, but meanwhile at least you can have your app compiling properly.

I hope it helps.

Best regards, Jesús.

So it seems like it might be a problem with later versions of ngx-bootstrap. In my package.json, I replaced "ngx-bootstrap": "^5.3.2" with "ngx-bootstrap": "5.3.2" , ran npm install and it built without any problems.

Answer 5

import { ModalModule } from 'ngx-bootstrap/modal';

This must be working.. simple solution

Answer 6

For some reason, the same package.json that's ran before, now doesn't works. The advice above work like a charm. Solution: remove the ^. "ngx-bootstrap": "^5.3.2" to "ngx-bootstrap": "5.3.2"

Answer 7

I am currently using Angular 9 with the latest version of ngx-bootstrap. I believe the latest implementation is to import the BsDatepickerModule in the app.module.ts file like this

Import statement in app.module.ts code:

import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { BsDatepickerModule } from 'ngx-bootstrap/datepicker';

in app.module.ts imports:

  imports: [
BrowserAnimationsModule,
BsDatepickerModule.forRoot()

]

Component Code:

import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { BsDatepickerConfig } from 'ngx-bootstrap/datepicker';

@Component({ selector: 'app-', templateUrl: './register.component.html', styleUrls: ['./register.component.css'],
})
export class RegisterComponent implements OnInit {


bsConfig: Partial<BsDatepickerConfig>;



constructor() {}

ngOnInit() {

this.bsConfig = Object.assign({}, { containerClass: 'theme-blue' });

}
}

package.json

"@angular/core": "~9.1.7", "bootstrap": "^4.5.0", "ngx-bootstrap": "^5.6.1", "@angular/cli": "~9.1.6"

From the official site:

Usage

import { BrowserAnimationsModule } from '@angular/platform-browser/animations';

// RECOMMENDED

import { BsDatepickerModule } from 'ngx-bootstrap/datepicker';

// NOT RECOMMENDED (Angular 9 doesn't support this kind of import)

import { BsDatepickerModule } from 'ngx-bootstrap';

@NgModule({

imports: [

BrowserAnimationsModule,

BsDatepickerModule.forRoot(),

...

] })

export class AppModule(){}
