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。

当我从谷歌CDN提供的css样式表的css链接中删除协议时，就发生了这种情况。

这不会产生错误:

<link rel="stylesheet" href="//fonts.googleapis.com/css?family=Architects+Daughter">

但是这会给出错误资源解释为样式表，但传输MIME类型text/html:

<link rel="stylesheet" href="fonts.googleapis.com/css?family=Architects+Daughter">

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)

使用角

在我的情况下，使用ng-href而不是href解决了这个问题。

注意:

我和laravel一起做后台

根据其他的回答，这条消息似乎有很多原因，我想我只是分享我的个人解决方案，以防将来有人有我的确切问题。

Our site loads the CSS files from an AWS Cloudfront distribution, which uses an S3 bucket as the origin. This particular S3 bucket was kept synced to a Linux server running Jenkins. The sync command via s3cmd sets the Content-Type for the S3 object automatically based on what the OS says (presumably based on the file extension). For some reason, in our server, all the types were being set correctly except .css files, which it gave the type text/plain. In S3, when you check the metadata in the properties of a file, you can set the type to whatever you want. Setting it to text/css allowed our site to correctly interpret the files as CSS and load correctly.

使用的反应

我在我的react profile应用程序中遇到了这个错误。我的应用程序表现得有点像它试图引用一个不存在的url。我相信这与webpack的行为有关。

如果你在公用文件夹中链接文件，你必须记住在资源之前使用%PUBLIC_URL%，就像这样:

<link type="text/css" rel="stylesheet" href="%PUBLIC_URL%/bootstrap.min.css" />
