Error with One-Click Install - Karma Release v2.052 - MacOSX

kateblanch opened this issue 7 years ago · comments

Hello! I'm not sure the best place to seek help for an error, but hoping you can help. After installing Karma via the one-click installer package, and starting it from the applications folder, I get this error.
Any ideas?
Thanks!

Can you type java -version on a console window and let us know what version of Java you have?

Thanks.

I see from the user guide I need Java 1.7 or higher...let me troubleshoot that.

Kate Blanch · Answer 4 · Wed Dec 20 2017 05:44:22 GMT+0800 (China Standard Time)

Ok, updated Java. Terminal java -version returns this:
java version "9.0.1"
Java(TM) SE Runtime Environment (build 9.0.1+11)
Java HotSpot(TM) 64-Bit Server VM (build 9.0.1+11, mixed mode)

When I restart Karma, I get this error.

Greetings! I have tried to sort out Java versioning. Still stuck. On a whim, tagging @caknoblock to see if he can help me untangle this or direct me to someone who could help. Disclaimer: I'm primarily a Windows admin, so this is a new OS for me.

When I try to Set Java Home from the Karma menu, I get an "invalid path for java" message.
Here is my path:
/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java

Here is the error that Karma now throws:
Starting Karma...
-Djava.endorsed.dirs=/Applications/Karma.app/Contents/Resources/app/tomcat/endorsed is not supported. Endorsed standards and standalone APIs
in modular form will be supported via the concept of upgradeable modules.
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
Launching Karma. Go to http://localhost:8080 if it doesn't launch.

Can you first try to set the Java Home in Karma as /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home instead and then restart Karma and see if that works.

If that doesnt, maybe we need to downgrade to JDK 1.8 and try.
For that, could you install JDK 8 - http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

And then type

/usr/libexec/java_home -v 1.8

on your console. This would give you the location of your 1.8 JVM. Can you copy that and set that as the Java Home in the Karma Menu and try again.

The correct Java home would look like: /Library/Java/JavaVirtualMachines/jdk1.8.0_151.jdk/Contents/Home

Hi Dipsy, thanks so much for the reply. This totally worked -- set the Java Home in Karma as /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home instead and then restart Karma.
I am up and running on Mac OS -- thanks so much and happy holidays :)!
