问题
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?
回答1:
you can try as follow:
First of all, build nutch via ant.
cd nutch-1.x.x/runtime/local/
mkdir urls (for seed list directory)
mkdir crawl (for -dir option)
vim urls/seed , then you add one or more than one url (ex:http://www.examplesite.com)
bin/nutch crawl urls --or-- bin/nutch crawl urls -dir crawl -depth 3 -topN 5

After some research I figured out that I forgot to set the NUTCH_JAVA_HOME. Here is the step:
set NUTCH_JAVA_HOME=/System/Library/Frameworks/JavaVM.framework/Versions/1.6/Home
export NUTCH_JAVA_HOME
And yes I reset the JAVA_HOME as well:
set JAVA_HOME=/System/Library/Frameworks/JavaVM.framework/Versions/1.6/Home
export JAVA_HOME
