npm install error: Package does not satisfy its siblings' peerDependencies requirements

Question

When i run npm install, I get the following errors:

npm ERR! peerinvalid The package @angular/core@7.2.15 does not satisfy its siblings' peerDependencies requirements! npm ERR! peerinvalid Peer @angular/animations@7.2.15 wants @angular/core@7.2.15

The installed version of @angular/core is indeed 7.2.15, but it's dependency @angular/animations says it needs version @angular/core 7.2.15

Any ideas?

I tried uninstalling/reinstalling @angular/core but still get the same error.

My package.json:

{ "name": "", "version": "0.0.0", "private": true, "dependencies": { "@angular/animations": "~7.2.0", "@angular/common": "~7.2.0", "@angular/compiler": "~7.2.0", "@angular/core": "~7.2.0", "@angular/fire": "^5.1.1", "@angular/forms": "~7.2.0", "@angular/platform-browser": "~7.2.0", "@angular/platform-browser-dynamic": "~7.2.0", "@angular/router": "~7.2.0", "@aws-amplify/ui": "^1.0.17", "@ngrx/store": "~7.2.0", "@types/pdfjs-dist": "^2.0.0", "aws-amplify": "^1.1.22", "aws-amplify-angular": "^2.1.9", "babel-polyfill": "^6.26.0", "core-js": "^2.5.4", "date-fns": "^1.30.1", "jquery": "^3.3.1", "firebase": "^5.8.3", "materialize-css": "^1.0.0", "ng2-pdf-viewer": "^5.2.4", "ngx-swiper-wrapper": "^7.2.1", "ngx-take-until-destroy": "^5.4.0", "pdfjs-dist": "^2.0.943", "rxjs": "~6.3.3", "tslib": "^1.9.0", "zone.js": "~0.8.26" }, "devDependencies": { "@angular-devkit/build-angular": "~0.13.0", "@angular/cli": "~7.3.0", "@angular/compiler-cli": "~7.2.0", "@angular/language-service": "~7.2.0", "@aws-amplify/cli": "^1.1.7", "@types/jasmine": "~2.8.8", "@types/jasminewd2": "~2.0.3", "@types/node": "^8.10.43", "@types/materialize-css": "^1.0.6", "codelyzer": "~4.5.0", "jasmine-core": "~2.99.1", "jasmine-spec-reporter": "~4.2.1", "karma": "~3.1.1", "karma-chrome-launcher": "~2.2.0", "karma-coverage-istanbul-reporter": "~2.0.1", "karma-jasmine": "~1.1.2", "karma-jasmine-html-reporter": "^0.2.2", "protractor": "~5.4.0", "ts-node": "~7.0.0", "tslint": "~5.11.0", "typescript": "~3.2.2" } }
