Ruby 3.3 (rc1) with Rails 6.1/7.0/7.1 with bootsnap fails

D-system · December 20, 2023, 12:56pm

Hello I’m investigating at using Ruby 3.3 but it fails at boot due to bootsnap. I got this error:

❯ rails c

        from bin/rails:4:in `<main>'

When I comment out the require "bootsnap/setup" from the boot.rb file, there is no issue. It fails here: ruby/lib/bundled_gems.rb at master · ruby/ruby · GitHub

Without bootsnap the variable name are like: net-smtp.
With bootsnap the variable name are like: -Users-thomas-.rbenv-versions-3.3.0-rc1-lib-ruby-3.3.0+0-mutex_m

It is a filepath that has been dash-ed here: ruby/lib/bundled_gems.rb at master · ruby/ruby · GitHub

I use a generated Rails 7.1.2 app with a single autogenerated scaffold on MacOS arm64. I have the same issue on non-hello-world project with Rails 6.1, 7.0 or 7.1.

Any idea?

The Ruby master branch has handled this, so it should no longer be a problem in the 3.3.0.

Thank you. I was not aware. ありがとうございます。じゃ、25日を待ってます。

Did you manage to make it work with Rails edge, Thomas ? It didn’t work on my end…

D-system · December 22, 2023, 1:52am

It’s an issue in Ruby itself. Rails edge won’t be able to solve that problem. You can:

use an earlier version: 3.3.0-preview3 works well
compile Ruby from the master branch
wait Christmas for the final 3.3.0 release
disable bootsnap until 3.3.0 release

I’m getting this error now with upgrading to Ruby 3.3.1. Is there a solution to this yet?

There’s an issue between Ruby and Bootsnap.

Rerun your command with DISABLE_BOOTSNAP=1 in front with Ruby 3.3.

Some gems will moved from Ruby core to a bundled gems (that needs to be in the Gemfile). There’s a list of all those gems here: https://www.ruby-lang.org/en/news/2023/12/25/ruby-3-3-0-released/

The list of future bundled gems:

abbrev
base64
bigdecimal
csv
drb
getoptlong
mutex_m
nkf
observer
racc
resolv-replace
rinda
syslog
