After changig my Rails app’s Gemfile to use Ruby 3.0.0 I get the following error when running bundle install:
~/.rbenv/versions/3.0.0/lib/ruby/3.0.0/digest.rb:16:in 'const_missing': library not found for class Digest::SHA256 -- digest/sha2.so (LoadError)

NB: I installed Ruby using rbenv and at first there was an SSL issue during installation, which I fixed (based on some suggestions found online) by pointing to the Homebrew-installed SSL library while running ruby-build (I am on macOS):
Curious. Does ~/.rbenv/versions/3.0.0/lib/ruby/3.0.0/x86_64-darwin19/digest/sha2.bundle exist? (or similar?)
Using Pry:
[3] pry(main)> $ Digest
From: /Users/jon/.rbenv/versions/3.0.0/lib/ruby/3.0.0/digest.rb:4
Module name: Digest
Number of lines: 75
module Digest
# A mutex for Digest().
REQUIRE_MUTEX = Thread::Mutex.new
def self.const_missing(name) # :nodoc:
case name
when :SHA256, :SHA384, :SHA512
lib = 'digest/sha2.so'
else
lib = File.join('digest', name.to_s.downcase)
end
begin
require lib
rescue LoadError
raise LoadError, "library not found for class Digest::#{name} -- #{lib}", caller(1)
end
unless Digest.const_defined?(name)
raise NameError, "uninitialized constant Digest::#{name}", caller(1)
end
Digest.const_get(name)
end
I could not find sha2.so in the require path, but sha2.bundle yes.
@joallard I have these files, there is no sha2 file:
$ ls ~/.rbenv/versions/3.0.0/lib/ruby/3.0.0/x86_64-darwin20/digest/
bubblebabble.bundle md5.bundle rmd160.bundle sha1.bundle
I’ve never used pry but after doing gem install pry I could get the same output as you showed (however, first I had to run require 'digest'):
$ pry
[1] pry(main)> require 'digest'
=> true
[2] pry(main)> $ Digest

Digest.const_get(name)
end

As to your last screenshot it seems to show paths with Ruby 2.7.2 whereas I am trying with 3.0.0. In bash I could run this (after running brew install fd), it does not find any sha2 file:
$ for path in `ruby -e "puts \$:"`; do echo $path; fd sha2 $path; done

OK I could workaround the issue by uninstalling rbenv (rbenv uninstall 3.0.0 && brew uninstall rbenv) and installing Ruby from Homebrew (brew install ruby). Now I get this
The following stdlib files are now default gems and are published on rubygems.org:
English
…
tmpdir
time
tsort
un
weakref
digest
I believe that explicitly adding this as a dependency in your Gemfile or .gemspec should fix the problem.
If you are using Bundler.require you won’t need to do anything else. If you are not, you are probably going to need to call require 'digest' somewhere in your code.
Thanks @etagwerker for the tip, however as per my previous comments I got things working just by removing rbenv and reinstalling Ruby 3.0.0 via Homebrew for some reason. I don’t have digest in my Gemfile (nor in Gemfile.lock).
