This is same as #1851. But I don't have any idea to resolve this yet. It may cause by global ruby configuration.

I've managed to install 3.2.1 after switching rbenv global to 3.1.2. It was not install when I had rbenv global 3.2.0

10:53 ~/ruby $ rbenv global 3.2.0
10:53 ~/ruby $ rbenv install 3.2.1

========================================

11:04 ~/ruby $ rbenv global 3.1.2
11:05 ~/ruby $ rbenv install 3.2.1

Installed ruby-3.2.1

Thanks for your input. It's strange result.

I had the same problem updating from 3.3.0 to 3.3.2.

./tool/file2lastrev.rb:6:in `require': cannot load such file -- optparse (LoadError)

i then proceeded to install 3.1.2. That worked. Then i set 3.1.2 to global and installed 3.3.2

I did pull from the rbenv master before and also i pulled the ruby-build master branch. I still had that optparse error.

So it seems like with 3.1.2 we can install other ruby versions but not with 3.3.0. This is just for people looking for a solution to this error. My system is fedora40 and i use rbenv exclusively.

I had the same issue and was only able to fix this by installing via mise instead of rbenv. Had to nuke rbenv, resolve to system ruby on ubuntu and go via mise.
