基本上我安装了 Mono Framework，然后是 Xamarin Studio。

创建了一个 Asp.Net 应用程序。跑了。收到此错误：

感觉像是许可，因为它可以构建并且我可以很好地运行控制台应用程序。

所以我尝试使用 sudo 从终端运行 Xamarin Studio App。然后问题就解决了。

但我不敢相信这是正确的解决方案。想知道是否有人知道如何正确运行它？

谢谢！

标签： c# asp.net macos xamarin mono

【解决方案1】：

使用终端查找“mcs”的位置

which mcs

它应该是 /usr/local/bin/mcs，它不在 Xamarin 的路径中。通过将 mcs 链接到 /usr/bin 来解决此问题

sudo ln -s /usr/local/bin/mcs /usr/bin

【讨论】：

/usr/local/bin/mcs 也不存在。

【解决方案2】：

我遇到了同样的问题，我从 Xamarin Studio 安装了最新的更新，问题得到了解决。

为此，请转到 Xamarin Studio 菜单 --> 检查更新...。您将看到可用更新的列表。下载并安装它们。

希望这会有所帮助！
