I’m having trouble installing RubyMine on my Ubuntu 8.10 desktop

I unpacked the file:

jason@jason-ubuntu-vm:~/Desktop$ sudo tar -xzvf rubymine435.tar.gz

change to the new directory, then to the bin directory

start the installer:

sudo ./rubymine.sh

then i get this error:

ERROR: cannot start RUBYMINE  
No JDK found to run RubyMine. Please validate either IDEA\_JDK or  
JDK\_HOME  
points to valid JDK installation.  
exec: 60: /bin/java: not found

i installed the java jdk (sudo apt-get install sun-java-jdk6), and it  
installed with no errors. my guess is that i need to edit a config file,  
but  
cannot figure out which one. Or maybe it’s something else.

thanks,  
Jason

Jason,

Often you can stuff an environment variable in your own space that  
defines what you need.

i.e. in ksh or sh (and maybe bash)

export JDK\_HOME=/full/path/to/jdk

Check the RubyMine install instructions. Also, if you’re just  
evaluating you might check out Sun’s NetBeans. It’s a fairly mature  
IDE with an active development community behind it.
