Hello,

No news on that bug/problem ?

I'm on MacOs and got the same since I use zsh (but I had a lot of other things to make it work)

hi, @ShamoX . Can you tell me the version of Ruby, IRB and Reline?
I couldn't reproduce the problem in my environment as follows.

% echo $LANG
ja_JP.UTF-8
% echo $LC_TERMINAL
iTerm2
% echo $LC_TERMINAL_VERSION
3.4.13
% echo $TERM

% echo $TERM_PROGRAM

% echo $TERM_PROGRAM_VERSION

% RBENV_VERSION=2.7.0 irb

=> "1.2.1"
irb(main):003:0> Reline::VERSION
=> "0.1.2"
irb(main):004:0>

Also, is it possible to do gem install irb to check with the latest version of irb?

Ahah, I'm waking up something old it seems.

In my terminal without Ruby version imposed by rbenv (using 2.7.0 installed on the system):

Also working on ruby 3 :

When using the same terminal that failed earlier (first instruction is a up arrow that failed when I filled up the message earlier):

So maybe rib changed because I did a rbenv global 3.0.2 in the other terminal.

So effectively, doing a rbenv global 2.7.0 and then I get back the error.

So I suppose the error is coming from a rebuild of some library with brew.

I try to rebuild the 2.7.0 and check if it works back.

It's worst that I though: This is probably of a remnant of the installation I had on a amd64 mac that came with the restauration mechanism since 2.7.0 don't compile on M1 chips.

I suggest you close that Issue until a new occurence comes with some solid ground :D

I was seeing this on my irb when I had a messed up terminal from some ssh nonsense. Running reset in the shell fixed that which fixed the irb issue as well.
