Apparently bundler 2.4 now requires that the `RUBY VERSION` versions be listed if the `Gemfile` contains a `ruby '...'` declaration. https://devcenter.heroku.com/changelog-items/2809 Although, I'm still not 100% certain that the ruby...

I have since removed the `gems/redcloth/CVE-2012-6684.yml` file. https://github.com/rubysec/ruby-advisory-db/commit/aa22f72bae6b0c94dbeafdcc5b75b39dc6d2b425

@Mizou04 feel free to submit a PR. I'm guessing an extra `if [[ ! -w "$install_dir" ]]; then` could be added to `bin/ruby-install`.

I have recently added some logic to dynamically install the `[email protected]` or `openssl@3` homebrew package depending on the version of Ruby. See a37e332e055da91db5fb053a3d94ebb0f219043d This will be released shortly in ruby-install...

`ruby-install` 0.9.0 will now recommend using `--update`, and if the given ruby version is unknown then `ruby-install` will auto-download new versions.

@monfresh since `ruby-install` can be ran as a regular user *or* as root via `sudo`, we have to run homebrew under the user which installed homebrew. We should probably not...

See issue #471. @monfresh I suspect a better solution specifically for homebrew being erroneously ran as `root` would be running the `brew` commands as the *original* non-root user (aka `$SUDO_USER`).

This is because `bin/ruby-install` `cd`s into `$src_dir/$ruby_dir_name`. So if the `src_dir` is relative, it won't be able to find the `$src_dir/$ruby_dir_name` while within `$src_dir/$ruby_dir_name`. We could change the `copy_into` call...

@lougreenwood maybe next week? I also wanted to add additional environment variables like `RUBY_INSTALL_PKG_MANAGER` or ~~`RUBY_INSTALL_DOWNLOADER` (`curl` or `wget`)~~ (I ended up deciding against this one env variable).

Closing this as I prepare for a 0.9.0 release. The `RUBY_INSTALL_RUBIES_DIR` environment variable have been added for configuring the default installation directory. If we want to add additional logic to...
