ensime scala 错误（未找到类 scala.Array，未找到对象 scala）
我已经根据 README.md 文件安装了 ensime，但是，我在 inferior-ensime-server 缓冲区中收到以下错误：

也没有任何类型识别对我有用，我如果我得到任何东西，就得到“NA”。 Cc t 导致 emacs 锁定。
我正在运行：
Ubuntu 10.04（64位版本）
emacs 23.1.50.1
来自 git 的 ensime（截至 2010 年 5 月 3 日）
scala 版本为 2.8.0.RC1
java是1.6.0_20（来自sun）

谢谢！

I've installed ensime according to the README.md file, however, I get errors in the inferior-ensime-server buffer with the following:

Also none of the type identification works for me, I get 'NA' if I get anything at all. C-c t causes emacs to lock up.
I'm running:
Ubuntu 10.04 (64bit version)
emacs 23.1.50.1
ensime from git (as of 3 May 2010)
scala is version 2.8.0.RC1
java is 1.6.0_20 (from sun)
here is a copy of the log: http://dl.dropbox.com/u/5309017/ensime.log
Thanks!

“scala.tools.nsc.MissingRequirementError: object scala not find”通常意味着无法找到标准 Scala 库。查看劣质 ensime 服务器缓冲区，它应该打印正在使用的类路径。这是我的摘录：
INFO: [Classpath = /usr/lib/jvm/java-6-openjdk/jre/lib/resources.jar:/usr/lib/jvm/java-6-openjdk/jre/lib/rt .jar:/usr/lib/jvm/java-6-openjdk/jre/lib/jsse.jar:/usr/lib/jvm/java-6-openjdk/jre/lib/jce.jar:/usr/lib/ jvm/java-6-openjdk/jre/lib/charsets.jar:/usr/lib/jvm/java-6-openjdk/jre/lib/rhino.jar:/usr/lib/jvm/java-6-openjdk/ jre/lib/ext/dnsns.jar:/usr/lib/jvm/java-6-openjdk/jre/lib/ext/pulse-java.jar:/usr/lib/jvm/java-6-openjdk/jre/ lib/ext/sunjce_provider.jar:/usr/lib/jvm/java-6-openjdk/jre/lib/ext/sunpkcs11.jar:/usr/lib/jvm/java-6-openjdk/jre/lib/ext/ localedata.jar：/usr/lib/jvm/java-6-openjdk/jre/lib/ext/gnome-java-bridge.jar：/home/aemon/src/misc/ensime/lib/jnotify/jnotify-0.93。 jar:/home/aemon/src/misc/ensime/lib/scala/scala-library.jar:/home/aemon/src/misc/ensime/lib/scala/scala-compiler.jar]
注意 scala-library。罐子，倒数第二个。您可能必须修改 .ensime 文件，以便 :classpath 字段指向库 jar。
"scala.tools.nsc.MissingRequirementError: object scala not found" usually means that the standard Scala libarary cannot be found. Have a look at the inferior ensime server buffer, and it should print the classpath that's being used. Here's an excerpt from mine:
INFO: [Classpath = /usr/lib/jvm/java-6-openjdk/jre/lib/resources.jar:/usr/lib/jvm/java-6-openjdk/jre/lib/rt.jar:/usr/lib/jvm/java-6-openjdk/jre/lib/jsse.jar:/usr/lib/jvm/java-6-openjdk/jre/lib/jce.jar:/usr/lib/jvm/java-6-openjdk/jre/lib/charsets.jar:/usr/lib/jvm/java-6-openjdk/jre/lib/rhino.jar:/usr/lib/jvm/java-6-openjdk/jre/lib/ext/dnsns.jar:/usr/lib/jvm/java-6-openjdk/jre/lib/ext/pulse-java.jar:/usr/lib/jvm/java-6-openjdk/jre/lib/ext/sunjce_provider.jar:/usr/lib/jvm/java-6-openjdk/jre/lib/ext/sunpkcs11.jar:/usr/lib/jvm/java-6-openjdk/jre/lib/ext/localedata.jar:/usr/lib/jvm/java-6-openjdk/jre/lib/ext/gnome-java-bridge.jar:/home/aemon/src/misc/ensime/lib/jnotify/jnotify-0.93.jar:/home/aemon/src/misc/ensime/lib/scala/scala-library.jar:/home/aemon/src/misc/ensime/lib/scala/scala-compiler.jar]
Notice the scala-library.jar, second from the end. You probably have to modify your .ensime file so that the :classpath field points to the library jar.
