当我尝试使用bundle变换器来转换.less文件时，我面临下面的异常，这个问题似乎是间歇性地发生而不是总是发生。
正如我可以看到JavascriptEngineSwitcher中存在一些Win32异常，有人可以帮助解决此问题的实际原因。 下面是stacktrace：

答案 0 :(得分：3)
为了正确使用MSIE JavaScript引擎，建议在服务器上安装Internet Explorer 9及更高版本。
您有2种变体可以解决此问题：
如果没有Internet Explorer 9或更高版本，BundleTransformer.Less将无法运行（将出现“Out of stack space”错误）。 执行大量JS代码时会发生此错误，即Bundle Transformer模块的大部分都会导致此错误。
