First check the console in the Developer tools of your browser for any errors ( use F12 or Ctrl + Shift + I to open dev tools). 首先,在浏览器的开发人员工具中检查控制台是否存在任何错误(使用F12或Ctrl + Shift + I打开开发工具)。 If there's no error in the console, then check if the file path you stated is present in the directory you are.
如果控制台中没有错误,请检查您所声明的文件路径是否在您所在的目录中。
