Javascript 字体/ionicons.ttf？v=2.0.0 404（未找到）-CSS-Anuglar-本地主机

有人能告诉我如何解决以下错误吗？ 我已经从网上下载了模板。尝试转换为2个角度分量。一切正常，我可以看到应用程序在本地主机4200下运行。但我不知道为什么会出现以下错误，并且应用程序中没有加载图标

在我的index.html中，我有以下url

 <link href='https://fonts.googleapis.com/css?family=Roboto' rel='stylesheet' >
 <link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet" >

控制台错误

我从SO尝试了所有可能的解决方案，但没有任何帮助

对于导入CSS的所有字体，返回404错误（未找到），您必须决定是否要使用：

• 谷歌字体：导入到你的HTML文件中
• 来自本地路径的字体，在项目中：在CSS文件中定义

你可以把它们结合起来，但是你展示了两种选择，你需要决定它，这样我们才能解决它

检查第一个URL是否出错：下载文件或返回错误

---

可能问题在于CSS文件中定义的路径，例如

src:url（“../font/roboto/roboto Medium.eot”）
在从github下载所需的dep文件并将其放入资产文件夹后，我终于解决了这个问题
感谢您的善意回复@Ignacio。我已经解决了我的问题。你的建议也是有效的解决方案。我做了一些傻事。我没有使用CDN，而是直接从github下载依赖文件，并将其放在我的工作区中，解决了所有问题
