出于某种原因,我无法使用jj的clojure REPL,我做的是git克隆github上的clojure存储库然后运行ant来构建它,然后我将jline-0.9.94.jar下载到clojure.jar的目录中,然后运行以下命令:
java -cp jline-0.9.94.jar:clojure.jar jline.ConsoleRunner clojure.main
并得到以下错误:
Exception in thread "main" java.lang.ClassNotFoundException: clojure.main

以下是我当前目录中的文件:
vvshs-macbook-2:clojure vvsh$ ls

我在clojure 1.1和lein repl上得到了同样的错误(似乎lein维护了自己的clojure版本).
顺便说一句,这是在mac ox 10.5.8

>>setup configure
Configuring HDBC-sqlite3-2.3.0.0...
setup: Missing dependency on a foreign library:
* Missing C library: sqlite3
This problem can usually be solved by installing the system package that
provides this library (you may need the "-dev" version). If the library is
already installed but in a non-standard location then you can use the flags
--extra-include-dirs= and --extra-lib-dirs= to specify where it is.
我该怎么办 ？
谢谢你的帮助
