Cannot find module angular/animations

Question

I am using webpack in angular2 and when I try to run my app I get an error stating

Cannot find module "@angular/animations"

package.json

{   "name": "angular-quickstart",   "version": "1.0.0",   "description": "QuickStart package.json from the documentation, supplemented with testing support",   "scripts": {     "start": "tsc && concurrently \"tsc -w\" \"lite-server\" ",     "e2e": "tsc && concurrently \"http-server -s\" \"protractor protractor.config.js\" --kill-others --success first",     "lint": "tslint ./app/**/*.ts -t verbose",     "lite": "lite-server",     "pree2e": "webdriver-manager update",     "test": "tsc && concurrently \"tsc -w\" \"karma start karma.conf.js\"",     "test-once": "tsc && karma start karma.conf.js --single-run",     "tsc": "tsc",     "tsc:w": "tsc -w"   },   "keywords": [],   "author": "",   "license": "MIT",   "dependencies": {     "@angular/common": "~2.4.0",     "@angular/compiler": "~2.4.0",     "@angular/core": "~2.4.0",     "@angular/forms": "~2.4.0",     "@angular/http": "~2.4.0",     "@angular/platform-browser": "~2.4.0",     "@angular/platform-browser-dynamic": "~2.4.0",     "@angular/router": "~3.4.0",     "angular-in-memory-web-api": "~0.2.4",     "core-js": "^2.4.1",     "rxjs": "5.0.1",     "systemjs": "0.19.40",     "zone.js": "^0.7.4"   },   "devDependencies": {     "awesome-typescript-loader": "^3.1.2",     "canonical-path": "0.0.2",     "concurrently": "^3.1.0",     "html-webpack-plugin": "^2.28.0",     "http-server": "^0.9.0",     "karma": "^1.3.0",     "karma-chrome-launcher": "^2.0.0",     "karma-cli": "^1.0.1",     "karma-jasmine-html-reporter": "^0.2.2",     "lite-server": "^2.2.2",     "lodash": "^4.16.4",     "primeng": "^4.0.0-rc.1",     "protractor": "~4.0.14",     "reflect-metadata": "^0.1.10",     "rimraf": "^2.5.4",     "tslint": "^3.15.1",     "typescript": "~2.0.10",     "typings": "^2.1.0",     "webpack": "^2.2.1"   },   "repository": {},   "main": "index.js" } 

My webpack.config.js file is

var htmlWebPack = require('html-webpack-plugin');  module.exports = {     entry: "./app/main.ts",     output: {         path: 'dist',         filename: "bundle.js"     },     module: {         loaders: [           {               test: /\.tsx?$/,               loader: 'awesome-typescript-loader'           }         ]     },     plugins: [     new htmlWebPack({         template: './index.html'     })     ] }; 

When I run the command like npm start, I get an error as mentioned above.

I even tried to install angular-animate using this command

npm install angular-animate

This is the error message I get

I also tried to uninstall angular-animate with the command

npm uninstall angular-animate

but it doesn't help me.

Perform below steps to make it work:

1. npm install @angular/animations@latest --save

2. import "BrowserAnimationsModule" from "@angular/platform-browser/animations" in your root NgModule (Without this, your code will compile and run, but animations will trigger an error)

3. In your component use imports from the new package like this - " import { trigger, state, style, transition, animate } from '@angular/animations'; "

This worked for me.
