ASP.NET MVC bundler 合并成功但是压缩失败 Minification failed. Returning unminified contents.

 ASP.NET MVC Bundle 按照相关网上教程配置完成后合并成功了，但是CSS并没有压缩成功，合并文件中有如下错误提示

上面的错误以注释的方式出现在文件中，实际中貌似没有对我的网站造成特别的影响，但是后面的内容没有压缩。
于是想是不是因为上面的错误，导致合并成功但是没有压缩成功呢，与是就是一个排除上面的错误。

虽然上面有说明行号，但是没有用啊~~于是突然想起来自己的VS中有按照了一个压缩的软件《Bundler___Minifier》
安装完成后，可以直接右键点击CSS文件进行单独压缩，如果有错误，可以在VS的【输出】中很方便的看出来。

在单独压缩时遇到一个问题："路径中具有非法字符。"
原因：存在跨域的路径 例如：图片可能应用了其他网络的路径图片！

在VS中对每个CSS单独压缩测试后，发现与上面的错误提示其实是一样的啊！！哈哈。
对每个错误都排查后，重新合并压缩，就没有问题了。




总结：一定要使用Bundler___Minifier对每个错误都排查掉，确保每个文件单独压缩都没有问题，这样在bundler时，才能成功合并并压缩。
