我的webpack.config.js文件是

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'
    })
    ]
};

当我运行npm start之类的命令时，出现如上所述的错误.

when i run the command like npm start, i get an error as mentioned above.

更新1

我什至尝试使用此命令安装angular-animate

i even tried to install angular-animate using this command

npm安装角度动画

npm install angular-animate

这是我收到的错误消息 我还尝试使用命令卸载angular-animate

this is the error message i get I also tried to uninstall angular-animate with the command

npm卸载角动画

npm uninstall angular-animate

但这对我没有帮助:(

推荐答案

执行以下步骤使其生效:

Perform below steps to make it work:

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

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

从根目录NgModule中的"@ angular/platform-b​​rowser/animations"导入"BrowserAnimationsModule"(如果没有此功能，则代码将编译并运行，但是动画会触发错误)

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)

在您的组件中使用从新程序包中的导入，例如-从'@ angular/animations'导入{触发，状态，样式，过渡，动画};"

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

这对我有用.
