I am a ruby rookie with a question I am running ruby 2.6.0p0 (2018-12-25 revision 66547) [x64-mingw32] my laptop is windows 10 I was going through the PDF versionb of a ruby intro book and I have a question about the "ri" command. The PDF file shows the following examples ri Array ri Array.sort ri Hash#each ri Math::sqrt But in each case I receive an error message of the form "Nothing known about xxx". Why is there no available info on these topics ? ================== Barry Kimelman <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> Virus-free. www.avast.com <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2> Unsubscribe: <mailto:[email protected]?subject=unsubscribe> <http://lists.ruby-lang.org/cgi-bin/mailman/options/ruby-talk>
