Description

I have the following error when starting irb :

I'm using :
IRB : irb 1.3.5 (2021-04-03)
RUBY : ruby 3.0.2p107 (2021-07-07 revision 0db68f0233) [x86_64-darwin19]
MAC OS :11.6 with Bash terminal

I'm not sure to understand where it come from.
Thanks for your help

+1. Note that on macOS 11.6.1 and Ruby 2.6.5p114... The error is no longer present if one uninstalls irb 1.3.7 and installs irb 1.3.6, and uninstalls reline 0.2.7 and installs reline 0.2.6.

Would you see if it reproduce with the latest version of irb and reline? You can install it with gem install irb --pre.

Thanks for you answers. The error remain with the last version of reline and irb.
No issue with irb 1.3.6 and reline 0.2.6 even with my version of ruby.

Thank you for your answer. But I was not able to reproduce this on my macOS 11.3. 🤔
What terminal emulator are you using? (e.g. Terminal.app, Alacritty, iTerm2, etc...)
Just to be sure, please let me know the results of running irb_info on a version of irb that can run.

📝 I'm trying version

  • macOS: 10.15.7 and 11.3.1
  • Terminal emulator: Alacritty
  • Ruby: 2.6.6 and 3.0.2
  • irb: 1.3.8.pre.11 (2021-10-09)
  • Reline: 0.2.8.pre.11
  • RUBY_PLATFORM: x86_64-darwin20

Hi, I'm using /Applications/Utilities/Terminal.app (shown as version 2.11) under macOS 11.6.1. Fwiw, Ruby is 2.6.5p114 via RVM. These reports are still true for me: 1, 2. Many thanks again for your time!

If `$TERM` is `vt102`, there are no `kend`, `khome`, `civis`, or `cnorm` in capabilities.
`TerminfoError` is raised in `Reline::Terminfo.tigetstr(capname)`, so it is rescued if it does not exist.
