使用 Angular 5 导入浏览器动画模块时意外的令牌"<"

Question

我正在尝试将browseranimationmodule添加到我的Angular 5项目中，我似乎正在发生一个非常愚蠢的错误。

Error: (SystemJS) Unexpected token <
    SyntaxError: Unexpected token <
        at eval (<anonymous>)
        at Object.eval (http://localhost:56700/app/app.module.js:15:20)
        at eval (http://localhost:56700/app/app.module.js:71:4)
        at eval (http://localhost:56700/app/app.module.js:72:3)
    Evaluating http://localhost:56700/node_modules/@angular/platform-browser/animations.js

如果我不将brosweranimationsmodule放在我的ngmodule的导入中，则该项目可以正常工作。

看来，当我在模块中加载时，它会搜索错误的位置，以找到不存在的文件。按照Angular站点上的说明时，我注意到它从 @Angular/Platform-browser/Animations/Animations中的一个级别降低。我假设我的系统有问题。谢谢

让我知道您是否需要更多文件。

Answer 1

我遇到了同样的问题，并且已经通过修改我的 systemjs.config.js 解决了它。如果您设置了NPM路径，则应添加以下行：

'@angular/animations': 'npm:@angular/animations/bundles/animations.umd.js',
'@angular/animations/browser': 'npm:@angular/animations/bundles/animations-browser.umd.js',
'@angular/platform-browser/animations': 'npm:@angular/platform-browser/bundles/platform-browser-animations.umd.js',

Answer 2

对于与我有相同问题的任何可怜的灵魂：

丢弃的错误实际上是一个404错误。由于所有内容都通过我的index.html(这就是我构建应用程序的方式(进行路由，因此当它找不到以a＆lt;的index.html为单位的文件时。为了解决这个问题，我在地图中的system.config.js中添加了这三行：

'@angular/animations': '/node_modules/@angular/animations',
'@angular/animations/browser': '/node_modules/@angular/animations/bundles/animations-browser.umd.js',
'@angular/platform-browser/animations':'/node_modules/@angular/platform-browser/bundles/platform-browser-animations.umd.js'
