I followed each and every step in the Apache Nutch Wiki. I am using MacOSX 10.8.3, my JAVA_HOME is perfectly set and can even see various command options when bin/nutch is executed (according to the wiki).

But when I use bin/nutch crawl urls -dir crawl -depth 3 -topN 5, I get the following error: 

bin/nutch: line 104: [: too many arguments
Error: Could not find or load main class Engines

FYI: I have already created a urls directory in apache-nutch-1.6/urls

Can any one tell what might be the problem?

经过一番研究，我发现我忘了设置 NUTCH_JAVA_HOME。这是步骤：

set NUTCH_JAVA_HOME=/System/Library/Frameworks/JavaVM.framework/Versions/1.6/Home
export NUTCH_JAVA_HOME

是的，我也重置了 JAVA_HOME：

set JAVA_HOME=/System/Library/Frameworks/JavaVM.framework/Versions/1.6/Home
export JAVA_HOME

您可以尝试如下：

首先，通过 ant 构建 nutch。

cd nutch-1.x.x/runtime/local/

mkdir urls（用于种子列表目录）

mkdir crawl（供-dir选择）

vim urls/seed，然后添加一个或多个 URL（例如：http ://www.examplesite.com ）

bin/nutch crawl urls- 或者 - bin/nutch crawl urls -dir crawl -depth 3 -topN 5
