ensime scala錯誤（class scala.Array not found，object scala not found）

Question

我已經根據README.md文件安裝了ensime，但是，我在下級服務器緩衝區中遇到以下錯誤：

也：

而且沒有任何的類型識別爲我工作，我得到 'NA' 如果我得到任何東西。 C-c t導致emacs鎖定。

我運行：

的Ubuntu 10.04（64位版本）
的Emacs 23.1.50.1
ensime從混帳（截至3 2010年5月）
Scala是版本2.8.0.RC1
的java是1.6.0_20（來自太陽）

謝謝！

「scala.tools.nsc.MissingRequirementError：object scala not found」通常意味着無法找到標準的Scala libarary。看看劣勢ensim服務器緩衝區，它應該打印正在使用的類路徑。以下是我的摘錄：

請注意scala-library.jar，從第二個開始。您可能必須修改.ensime文件，以便：classpath字段指向庫jar。
