I've followed the readme but am getting this error and can't start Rails.

Stubbing the "debug" gem and rebuilding resolved this for now.

I also see this; commenting out the debug gem in Gemfile also seems to avoid this. This is on M1 mac-mini; I have an Intel MBP and the same git pull has no problems on that machine. Not sure if something else is different (e.g., homebrew package versions, build tools versions, etc.), or if arch is relevant.

Digging deeper into this, this appears to possibly be an intersection of reline + tmux (which is being used by overmind).

In the comments, a workaround is documented here:

"As a workaround, I added the line set -g default-terminal screen-256color in my ~/.config/tmux/tmux.conf."

For me, this file is ~/.tmux.conf, but this workaround did indeed work for me.
Ben Richardson
Thats great - thanks very much - worked perfectly 😃

For anyone else running into this issue (replace "code" with whatever your cli shortcut is for your editor):

1. run in terminal code ~/.tmux.conf
2. paste set -g default-terminal screen-256color into the file
3. re-run bin/dev
