I'm trying to install on Windows 10 (64 bit) and getting this error: 'An internal error occurred (error code: 20)'

[Koehd896]

This is the log:

Log: C:\Users\raven\AppData\Local\Temp\i4J_nlog_4.log

I'm happy to provide any other information that would be relevant

[headius]

Can you provide the content of the log? Use https://gist.github.com please.

[Koehd896]

Thanks for the response! Unfortunately this is all I'm getting for the log:

Log: C:\Users\raven\AppData\Local\Temp\i4J_nlog_4.log

[headius]

That line should indicate a file containing information about what happened during the install. Does the file exist? If so, can you post the contents using https://gist.github.com?

I had issues using the installer for the latest version as well.

I'm having the same issue too. I'll be glad to be helped.
My log file is: https://gist.github.com/mash-97/37f93368276161999db9486614d61819
Thank You!

[headius]

It looks like this is due to Java 14 not shipping the unpack200 utility anymore. We will need to modify the installer to no longer use pack200.

It would probably be possible for you to complete the install with an older version of Java or perhaps to I stall those unpack commands some other way.

Okay, I got it. I'll try to use some older versions of java then. Hope that will work. Thank You!

@Koehd896 @madrob If you are unable to get the installer to work with an earlier JDK, you can always just download the zip, unpack it, and put it somewhere in your PATH. That's really all the installer does for you. JRuby will run fine with newer JDKs, but the installer needs to be fixed.

[headius]

I believe removing the pack200 attribute from this line in the install4j config will solve the issue:

jruby/install/jruby.install4j

Line 4 in a61aebd

<application name="JRuby" distributionSourceDir="" applicationId="4535-5096-5383-5182" mediaDir="." mediaFilePattern="${compiler:sys.shortName}_${compiler:sys.platform}_${compiler:sys.version}" compression="9" lzmaCompression="false" pack200Compression="true" excludeSignedFromPacking="true" commonExternalFiles="false" createMd5Sums="true" shrinkRuntime="true" shortName="jruby" publisher="JRuby Dev Team" publisherWeb="http://www.jruby.org/" version="${compiler:jruby.version}" allPathsRelative="true" backupOnSave="false" autoSave="false" convertDotsToUnderscores="true" macSignature="????" macVolumeId="720835987edcfb24" javaMinVersion="1.7" javaMaxVersion="" allowBetaVM="false" jdkMode="runtimeJre" jdkName="">

I will file a separate issue to remove all pack200 references from all maintained branches.

@mash-97 If you're using a ruby on Windows, you might want to use uru.

What I did to work around this issue was use the zip version provided by the JRuby.org and add it to the list of ruby versions managed by uru. I was to able to use JRuby using Java 14 by doing this.

[mash-97]

Dear @preetpalS,
Though I'm having an warning, but yeah! it's working good the way you suggested. That helped me to run JRuby on windows. Thank You!

[headius]

This is fixed for 9.2.14 and 9.3. If you need to install JRuby before then, use a JDK version prior to 14, since that's when these tools were removed, or install from the zip file by unpacking and putting in PATH (or using a Ruby install manager like "uru" mentioned above).
