This problem has been reported in the past and apparently solved by an update to mini_racer. But I've hit a brick wall here that I can't get past so it appears to be the same problem again but possibly for different reasons. I have encountered the problem first when I tried to upgrade from Ruby 3.0.2 to Ruby 3.1.0, and had the same problem with a fresh install of everything. Also, when I tried to switch back to Ruby 3.0.2 and run bundle install I got exactly the same error.
I've also tried using older versions of mini_racer, with no change. I don't have the knowledge to debug mini_racer or bundler. The mkmf.log file didn't tell me anything useful but I don't know how to decrypt it.
When I run bundle install I consistently get the following. The files indicated in the troubleshooting steps are many layers beyond my understanding to begin to dig into what might be going wrong. It's the same error previously reported for earlier mini_racer / Ruby versions but I haven't found a current solution.

I am in the process of trying to upgrade my project from Ruby 3.0.4 / Rails 6.1.4 to Ruby 3.1.3 / Rails 7.0.8. Rebuilt existing project that was previously running successfully in Ruby 3.0.4 / Rails 6.1.4 Upgraded Rails to 7.0.8 - bundle install completed successfully Switched to Ruby 3.1.3 - bundle install failed (expected to pass) - error as described Switched to Ruby 3.1.0 - bundle install failed (expected to pass) - error as described Switched to Ruby 3.0.4 - bundle install failed (expected to pass) - error as described
Rebuilt project from a clean install (Ubuntu 22.04.3) with Ruby 3.1.0 - bundle install failed (expected to pass) error as described
To quote Andy Allan from rubyjs/mini_racer#289:
For anyone else coming across this, this was caused by a bug in rubygems < 3.4.9. So you can also fix it on older versions of ruby (e.g. ruby 3.0, 3.1) by updating your version of rubygems:
gem update --systemSee rubygems/rubygems#6490 for the PR in rubygems that fixed this bug, which was released in rubygems 3.4.10.
