The above .irbrc works with irb 1.6.x, but any later version I tested failed. I haven't bisected, but starting from 1.7.2, I guess? -- #623

I know I can just omit the require and the problem is gone, but I've filed this anyway because the error was so unexpected.

The file
irb/ext/historydoes not exist anymore.In my environment, these two require requires a file from different IRB version.

I'm sorry for the trouble. The require hasn't been needed for a long while (since as least IRB v0.9.6) as
Context#eval_historywould load it whenIRB.conf[:EVAL_HISTORY]is set. So when I was implementing #623, I considered it as an implementation detail instead of a public component.knu commentedon Dec 6, 2023
Thank you both! So, the solution here is to just remove the require as I said and it'll work also for reasonably old versions of irb, correct?
st0012 commentedon Dec 6, 2023
Yes. From my testing, it should work at least with IRB v1.2.0 without the require (can't test earlier due to other errors).

Thanks for your investigation. It took me some time to figure out what was going on from the error output because nothing was found on Google, so I hope whoever encounters this problem in the future will find this issue and the solution.
