I am unable to install any version of ruby. Please help.

any luck, im also facing same issue?

[premshiva143]

I never reproduce it. If you provide the instructions for reproducing this, I can help you.

Which version of mac os you are using?

[gkatsanos]

same issue

[sidewaysdesign]

I'm also experiencing this exact issue, under MacOS Monterey.

[MuhammedZatar]

Has anyone found a fix for this? running into too. Running MacOS Monterey (12.2.1).

[mohanzhang]

I ran into this today and ended up fixing it through one or more of these steps (sorry, this wasn't a very well-controlled experiment):

1. brew update
2. brew upgrade
3. (rbenv install still wasn't working at this point)
4. Went nuclear and reinstalled xcode developer tools (this will take a while): https://apple.stackexchange.com/questions/93573/how-to-reinstall-xcode-command-line-tools
5. brew uninstall --ignore-dependencies ruby-build
6. brew install ruby-build
7. rbenv install 2.7.6 <-- suddenly works!

Again, not sure which of these steps is strictly necessary, but I have got past this issue and figured I'd share it here in case it helps anyone else.
