Chrome跨域问题

从网上下载的html本地运行，出错，按F12，发现：

Access to script at 'file:///F:/xxx/yyy.js' from origin 'null' has been blocked by CORS policy: Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https.

按网上解决方法，在chrome快捷方式“目标”：

"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --allow-file-access-from-files

运行不出这个错了，又换了一个错误：

Failed to load module script: The server responded with a non-JavaScript MIME type of "". Strict MIME type checking is enforced for module scripts per HTML spec.

还是没有解决，win10上正好有Ubuntu，进入html目录，运行：

python -m SimpleHTTPServer 8080

就启动一个服务器了，再在chrome里输入：

http://localhost:8080/

就可以选择打开需要的网页了，运行OK。
