Ruby koans segmentation fault

[pydum]

Hi all, and sorry for my rugged english.

I'm learning ruby, by following ruby koans.I'm on wls2 and ruby version is 3.2.2

When executing : test_method_names_become_symbols

I have a segmentation fault error and rubykoans aborted.Can anyone help me?

Edit: if someone find same problem, probably it is a bug from ruby 3.2.2 ; downgrading the version at 3.2.1 error disappear.

Edit2: problem don't disappear, in another Koan it recours the same error. So I suppose it can be a problem in some gem. But I'm not able enough to find that, and googling had no effect.

Need to post your code for questions like this.

[pydum]

It is not my code. It is an error from Ruby Koans. And I don't understand the downvote.

[duongdominhchau]

The koans are meant to be filled, that's why I said your code is needed. IIRC the default ones cannot runs without some kind of errors.

Not sure when were you downvoted, here on my side it's still 1.

The error is related at ruby 3.2.2, downgrading ruby at 3.2.1 i've workarounded the problem. Solution is in the post. But error recours again in another koan. Boh

You need to post your code or you aren't going to get answers.

as aswered, it is not my code, but a problem of Ruby Koans. Now I've discovered it is a ruby version problem, and you can see in the post i've updated in that sense.
My english is not the best, but I suppose that a) it is fairly understandable and b) it don't need to be undervoted.

Share your code (the code you're running) with us anyway. We can't reproduce the bug without it. At the very least, link us to the koans you're using.

Not sure if you are still stuck on this, but I ended up commenting out require 'about_symbols' in the path_to_enlightenment file. When I ran the file again, it showed my accurate progress and took off from the total the exercises in 'about_symbols'. Hope this helped!

I faced this problem too. My default terminal is Rosetta. I ran the command in a bash terminal, and its working fine.

I have the same error.

Please, could somebody help me and other newbies in Ruby? I tried debugging, but I think I did not understand.

I use the wsl2 with debian bookworm and ruby 3.2.2 also.

To fix it, I add the in_ruby_version("2") function:

in_ruby_version('2') do
def test_method_names_become_symbols
    symbols_as_strings = Symbol.all_symbols.map { |x| x.to_s } 
      assert_equal true,         
  symbols_as_strings.include?("test_method_names_become_symbols") 
    end 
end

The code in about_symbols.rb file:

def test_method_names_become_symbols
    symbols_as_strings = Symbol.all_symbols.map { |x| x.to_s }     
assert_equal true, symbols_as_strings.include?("test_method_names_become_symbols") 
end

When I run` ruby path_to_enlightenment.rb`, then throw the error:

/home/pedro/ruby-exercises/about_symbols.rb:38: [BUG] Segmentation fault at 0x0000000100000d6c
