0.9.1.beta2 does not work with Ruby 3.3

[tagliala]

$ mailcatcher -f -v --http-ip=0.0.0.0
Starting MailCatcher v0.9.1.beta2
==> smtp://127.0.0.1:1025
==> http://0.0.0.0:1080

Unfortunately I cannot run specs on my machine, it looks like that there are issues with base64 (no longer a default gem) and maybe more

This issue is affecting 0.9.0 release on ruby 3.3.0

If the fix is just upgrading the dependencies then this needs to be merged and released because mailcatcher is unusable for anyone who is running ruby 3.3 currently.

Also just noticed this investigating a failing healthcheck for mailcatcher. Here's a minimal repo:

docker run -it ruby:3.3.0 /bin/bash
gem install mailcatcher
mailcatcher --http-ip=0.0.0.0 --no-quit
curl localhost:1080 # Internal server error

I'm also seeing this issue on Ruby 3.3.0. Is there a workaround?

Use rbenv or rvm, and cd into a folder configured to use an older ruby version before starting mailcatcher.

e.g.:

> mkdir mailcatcher
> cd mailcatcher
> echo "3.2.2" > .ruby-version
> echo "ruby 3.2.2" > .tools-versions
> asdf install
> gem install mailcatcher
> mailcatcher --foreground

Pushed to rubygems — please try it out:

gem install mailcatcher --pre

After a couple of good reports I will promote this to v0.10.0.

@sj26 It works for me! 😄

Works for me with Ruby 3.3.0 and Rails 7.1.
