我创建了一个新的angular-cli(版本1.0.5)项目并添加了npm模块ng2-spin-kit(版本1.3.0)。然后我修改文件 src / app / app.module.ts 和 src / app / app.component.html 以测试组件 WaveComponent
构建和启动服务器(ng serve
)可以正常工作。但是在浏览器中启动应用程序会导致此启动失败:
Uncaught Error: Unexpected value 'WaveComponent' declared by the module 'AppModule'. Please add a @Pipe/@Directive/@Component annotation.

完整项目可用于:
https://github.com/ManfredSteiner/ng2-cli-test-spin-kit
在跟踪源(在vscode中)时,WaveComponent源可用。捆绑包也包含此组件。
任何想法出了什么问题?我可以检查找出原因?
答案 0 :(得分:0)
对我而言,似乎你的版本与@angular软件包有冲突(常见,编译器,平台浏览器等。检查npm上的ng2-spin-kit依赖关系)。
Ng2-spin-kit使用版本2,您的项目使用版本4.
我尝试将ng2-spin-kit添加到cli项目中,该项目使用这些库中的版本2,旋转器就像魅力一样。
如果你坚持使用角度版本4,我没有你的解决方案,但是如果版本2没有问题,那么:
我能做这项工作的方式是:
npm install ng2-spin-kit --save
