"Problem installing rapidminer on mac"

Hi to all

I have tried to download and execute rapidminer but it does't work.

My SO is MAc os x 10.5 so i decide to download the zipfile
before unziping i tried to lunch (doble clic) on lib/rapidminer.jar. FAIL
i have grant de execution of script file (rapidminergui and rapidminer). he tel me that output

macbook-di-gaetano-pottino:scripts gaetanopottino$ ./rapidminer
RAPIDMINER_HOME is not set. Trying the directory '.'...
No maximum Java memory defined, using 512 Mb...
Neither ./build nor ./lib/rapidminer.jar was found.
Try 'ant build' or 'ant dist' first or check the value of RAPIDMINER_HOME!

i have tried to set this:
## set the path to your RapidMiner installation here or in an environment variable
RAPIDMINER_HOME=${/Users/gaetanopottino/Downloads/rapidminer} FAIL

Some people know how to start it?

ps: i have already install java 1.6 like you see

macbook-di-gaetano-pottino:scripts gaetanopottino$ java -version
java version "1.6.0_22"
Java(TM) SE Runtime Environment (build 1.6.0_22-b04-307-9M3263)
Java HotSpot(TM) 64-Bit Server VM (build 17.1-b03-307, mixed mode)
macbook-di-gaetano-pottino:scripts gaetanopottino$

Thanks for your time

Hi,
what happens if you start a console, go to the RapidMiner directory and type "java -jar ./lib/rapidminer.jar" ?

Hi,

I also work with Mac but I have got no problems...

But, like you, I have got similar "error" messages

G Nov 18, 2010 11:06:02 AM: Property rapidminer.home is not set. Guessing.
G Nov 18, 2010 11:06:02 AM: Trying parent directory of '/users/Edin/rapidminer/lib/rapidminer.jar'...gotcha!

Try this:

1. unzip rapidminer to your user directory
2. open your terminal and type in following command

cd rapidminer (or your directory) && cd lib && java -Xmx1600m -jar rapidminer.jar

The "-Xmx1600m" allows RapidMiner to use the max. RAM of 1,5 GB.

I use RM 4.6 but I suppose this will also work with 5.0.

Happy Trying,

Edin

Hello. I looked at the above possible solutions and still have problems installing rapidminer on my Mac. I have OS X V10.4.11 and when trying to do the above got the following message from the console:

Any suggestions? I appreciate anyone's help on this. Thank you very much.

Hi,
from your error message I assume that you will need to install Java 1.6. RapidMiner is not Java 1.5 compatible.

With kind regards,

I have not received the confirmation email and I already tried with two accounts, I cannot start working with the tool since I get a Warning that says that I do not have the account verified
