Mindtouch dekiwiki 服務在啟動時崩潰（缺少裝配錯誤）

這是在 Ubuntu 10.04 上新安裝的 Mindtouch Core。我一直在關注Mindtouch 社區網站上的安裝指南。

當我嘗試啟動 dekiwiki 服務時，它崩潰並出現以下錯誤：

** (/var/www/dekiwiki/bin/mindtouch.host.exe:14465): WARNING **: The following assembly referenced from /var/www/dekiwiki/bin/mindtouch.core.dll could not be loaded:

我已經仔細檢查了，我已經安裝了 Mono 2.10，並且 System.Web.Routing 程序集肯定在那裡，Mindtouch 只是沒有找到它。

有任何想法嗎？

弄清楚了。

安裝說明底部有一條註釋，說明通過執行檢查單聲道版本mono --version。

果然，/usr/bin/mono還在執行 Mono 1.x。

我執行以下操作以確保 Mono 2.10 正在執行，並且一切都像魅力一樣啟動。

mv mono mono.old
mv gmcs gmcs.old
ln -s /opt/mono-2.10/bin/mono /usr/bin/mono
ln -s /opt/mono-2.10/bin/gmcs  /usr/bin/gmcs
