Help starting clojure, a possible problem with the class

Question

admin@apollo:~/clojure$ clojure
Clojure 1.0.0-
user=> (require 'clojure.contrib.str-utils)
java.io.FileNotFoundException: Could not locate clojure/contrib/str_utils__init.class or clojure/contrib/str_utils.clj on classpath:  (NO_SOURCE_FILE:0)

What did I do wrong when installing clojure? Why can not clojure find my java classes? I have Java installed.

admin@apollo:~/clojure$ sudo apt-get install sun-java6-jre sun-java6-jdk
sudo: unable to resolve host apollo

Please, help! thank!

Answer 1

It's great to learn how to figure it out manually, because understanding the classpath makes the world a better place. In practice, many gummies use leiningen, maven or cake.

Personally, I would recommend using leiningen :

• wget http://github.com/technomancy/leiningen/raw/stable/bin/lein
• make it amazing and save it somewhere like ~ / bin or / usr / bin or something else.
• lein new MY-PROJECT-NAME
• lein deps
• lein repl
• !
