如果你在prod中提供应用程序，请确保你在service worker中提供静态文件。当我在Django上只提供React构建的静态子文件夹时，我遇到了这个错误(没有具有样式的资产)

我也面临着同样的问题。在做了一些研究之后，我发现问题出在文件名上。实际文件的名称是“lightgaly .css”，但在链接时我输入了“lightgaly .css”。

更多信息:

它在我的本地主机上运行良好(操作系统:Windows 8.1 &服务器:Apache)。 但是当我将我的应用程序上传到远程服务器(与我的本地主机不同的操作系统和Web服务器)时，它不起作用，给了我和你一样的错误。

因此，问题是服务器的大小写敏感性(与文件名有关)。

使用ReactJs，当我添加样式文件到index.html使用相对链接，如

<link rel="stylesheet" href="./css/style.css"> .

然后我导航到一条路线，说;localhost:3000/artist和刷新，我得到错误。

错误消失后，我取代相对链接与绝对链接说;

<link rel=“stylesheet” href=“http://localhost/project/public/css/style.css”。

In my case, same error was coming with JSP. This is how I got to the root of this issue: I went to the Network tab and clearly saw that the browser request to fetch the css was returning response header having "Content-type" : "text/html". I opened another tab and manually hit the request to fetch the css. It ended up returning a html log in form. Turns out that my web application had a url mapping for path = / Tomcat servlet entry : (@WebServlet({ "/, /index", }). So, any unmatching request URLs were somehow being matched to / and the corresponding servlet was returning a Log in html form. I fixed it by removing the mapping to /

此外，tomcat配置wrt处理css MIME-TYPE已经存在。

I faced the same issue while configuring Postfix Admin 3.2. According to the official documentation, the whole Postfix Admin content should be extracted into a separate directory, i.e. /srv/postfixadmin and not the document root. Only the /srv/postfixadmin/public directory should be symlinked into /var/www/html document root. I have just extracted the whole content into /var/www/html. Having played with Nginx server block settings, I managed example.com/postfixadmin resolving from /var/www/html/postfixadmin/public. Nevertheless, images and CSS were not available with 404 status code. The stylesheets were broken. I got the error message OP quoted with respective 404 entries in access log.

在我的情况下，我只是移动/var/www/html/postfixadmin到/srv/postfixadmin和ln -s /srv/postfixadmin/公共/var/www/html/postfixadmin。这完全解决了问题。 这是参考资料。

我有同样的问题，几分钟后，我破译，我错过了添加文件扩展名到我的头。所以我改了下面这行:

<link uic-remove rel="stylesheet" href="css/bahblahblah">

to

<link uic-remove rel="stylesheet" href="css/bahblahblah.css">
