Sublime 调试Three.js文件遇到浏览器跨域问题

在运行three.js开源项目的时候遇到如下的错误，如图：

运行demo项目报错

three.js:34636 Access to XMLHttpRequest at 'file:///Users/mac/three.js-master/examples/models/collada/elf/elf.dae' 
from origin 'null' has been blocked by CORS policy: 
Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https.
load @ three.js:34636
three.js:22676 THREE.WebGLRenderer 104

解决方案

1.解决浏览器跨域问题

参考 Mac上Chrome浏览器跨域解决方案
在浏览器中改变本地文件的安全策略，这将使你可以通过

file:///yourFile.html

2.从本地的服务器运行文件，这可以让你通过

http://localhost/yourFile.html

如何开启本地服务器请参考：Three.js官方文档
