"rvm docs generate" is killed

Question

Any idea why rvm(1.18.15) fails to generate the document for ruby2.0?

$ rvm docs generate

ri documentation, be aware that this could take a long time, and depends heavily on your system resources...
( Errors will be logged to /home/user/.rvm/log/ruby-2.0.0-p0/docs.log )

Below is the content of the docs.log.

Answer 1

this is rdoc / ruby issue:

• https://bugs.ruby-lang.org/issues/8037
• https://github.com/rdoc/rdoc/issues/193
• https://github.com/rdoc/rdoc/issues/194

you can overcome this problem by reinstalling ruby with --docs flag:

rvm get head
rvm reinstall 2.0.0 --docs
