Based on the backtrace, it fails on Bundler.bundle_path.to_s.

Could you run the following ?

bundle exec ruby -e 'p Bundler.bundle_path; p Bundler.bundle_path.to_s'

Here's where it fails in Ruby itself: https://github.com/ruby/ruby/blob/0db68f023372b634603c74fca94588b457be084c/ext/pathname/pathname.c#L80-L81

This suggest somehow a Pathname as set with an internal path that isn't a String. No idea how that can possibly happen. That's very likely a problem with your development environment and not Bootsnap itself, but I'll leave this open for a bit to see if we can get to the bottom of it.

The underlying bug can be reproed with:

>> Pathname.new("/").tap { |p| p.instance_variable_set(:@path, nil) }.to_s
(irb):3:in `to_s': unexpected @path (TypeError)

The question being what in your environment might be doing such a thing.

Hey, I've been having the exact same problem while running rails new ProjectName. I'm still fairly new to Rails so I don't know how to work around it or what might be causing it. Tried reinstalling rails, also installing a different version, but it doesn't solve the problem.

Here's my output for bundle exec ruby -e 'p Bundler.bundle_path; p Bundler.bundle_path.to_s'

#<Pathname:/home/<username>/.rbenv/versions/3.0.2/lib/ruby/gems/3.0.0>
"/home/<username>/.rbenv/versions/3.0.2/lib/ruby/gems/3.0.0"

Edit: I managed to create a new project by following this workaround but I still get the same error while doing rails s now.

EDIT 2: Somehow the issue got resolved by removing all gems, installing rails (and dependencies) again and rehashing rbenv shims.

Still uses bootsnap 1.9.1 so it probably isn't an issue of bootsnap.

Well, another take on this issue: My problems start much later, i.e. when trying to deploy. The following is from the Capistrano log:

Hum, your pathname is loaded twice because of rubygems/rubygems#4992, it could be the root cause or not. Either way I'll be closing this because I'm pretty sure it has nothing to do with bootsnap. If you want to prove it, you can set DISABLE_BOOTSNAP=1, if the still bug happens it's not a bootsnap bug.

Thanks for the pointer!

Just for reasons of completeness: I purged all installations of and references to pathname version 0.2 on dev and server; afterwards I was able to deploy again.

No idea, how this version had been installed in the first place; might have been a too careless gem update.
