Your system is ready to brew.

Description of issue

Terminal floods with progress bar characters on brew update/upgrade/install. I have included an asciinema recording.

https://asciinema.org/a/tUTt2DH5KcBZDTHZuI1ci8i53

I have read of an issue with the progress bar taking up extra lines in terminals narrower than 80 columns, but the screenshots in those cases appear different, and my issue happens no matter how many columns are available.

Homebrew/brew#981
Homebrew/brew#1002

Any idea what gives?

Might be /snap/ruby/369/bin/ruby, or some interaction with it and how brew and its subprocesses gather information about your terminal.

Can you reproduce it with a ruby you've installed through rbenv?

In a pinch, you can try passing -q or --quiet.

Can you reproduce it with a ruby you've installed through rbenv?

Thank you for the quick reply!

Forgive my ignorance, but I am not entirely sure what a ruby is in this context or how I would go about reproducing this behavior with one.

[carlocab]

Homebrew is built using Ruby, so it needs a ruby binary to run. Yours seems to be found at /snap/ruby/369/bin/ruby.

I suggest trying:

brew install --quiet rbenv openssl@3
eval "$(rbenv init -)"
export RUBY_CONFIGURE_OPTS="--with-openssl-dir=$(brew --prefix openssl@3)"
rbenv install 3.3.5

Once that's done (it may take a while), the output of ruby --version and which ruby should look something like (sans the arm64-darwin23 part)

❯ ruby --version
ruby 3.3.5 (2024-09-03 revision ef084cc8f4) [arm64-darwin23]

❯ which ruby
/path/to/home/.rbenv/shims/ruby

Once you've done that, paste the output of brew config here and then try brew install again.

This seems to have done the trick. Thanks!

I figure the output of brew config probably isn't important now, but in case it is:

Great. You'll want to add

eval "$(rbenv init -)"

to your shell startup scripts (e.g. .bashrc, .zshrc, .bash_profile, or similar) to make sure that /home/annehiiro/.rbenv/shims is in your PATH for brew to find it. You may need to do it after doing brew shellenv (if you use it), but before any other usage of brew.
