Mono MVC3 无法映射路径

Question

我正在尝试让 MVC3 应用程序在单声道下运行，并且在部署到我的服务器之前一切都很顺利...

我目前得到：

Failed to map path '/projects/_ViewStart.cshtml'

System.InvalidOperationException: Failed to map path '/projects/_ViewStart.cshtml'

  at System.Web.Mvc.ControllerActionInvoker.InvokeActionResultFilter (IResultFilter filter, System.Web.Mvc.ResultExecutingContext preContext, System.Func`1 continuation) [0x00000] in <filename unknown>:0 

错误。我可以确认所有文件和 DLL 都存在，但路径看起来不正确，肯定它应该在视图文件夹中查找确实存在的东西吗？

是否需要进行某种设置以确保它位于正确的视图位置？我还注意到文件路径之前没有“~”字符...

我浏览了网络并尝试了各种解决方案，但似乎没有一个有效..

Answer 1

看看你的 Apache 配置，对我来说是这样的

运行失败 '/usr/bin/mod-mono-server2 --filename /tmp/mod_mono_server_bla --applications /testmono:/var/www/ModMonoMvc3Application --nonstop (null) (null) (null) (null) （空）（空）（空）'。原因：没有那个文件或目录

因为我误解了配置选项AddMonoApplications。它应该是这样的：

# "default" is defined in mods-available/mod_mono.conf
AddMonoApplications default "/testmono:/var/www/ModMonoMvc3Application"

<Location /testmono/>
    SetHandler mono
</Location>

我不小心写了“bla”而不是“default”，因为我以为它是应用程序名称，但实际上它定义了启动哪个服务器可执行文件。

直接调用时遇到同样的错误

HttpContext.Current.Server.MapPath("/") 或

HttpContext.Current.Server.MapPath(Path.DirectorySeparatorChar.ToString()) 

但这是可行的：

HttpContext.Current.Server.MapPath("~")
