I can't install ruby 3.0.3. Tried many different options.

Install log mostly consists of the lines like this

MacOS Monterey 12.2.1, rbenv 1.2.0, ruby-build 20220125. Same happened back when I was on Big Sur (so I upgraded but no luck).

brew outdated gives nothing. I also tried reinstalling gcc, command line tools and did everything suggested by brew doctor.

Any help appreciated!

Solution 1:[1]

There were lots of issues related to linking of openssl and possibly smth else.

Solution:

brew update
brew upgrade
brew install llvm
export PATH="/usr/local/opt/llvm/bin:$PATH"
export LDFLAGS="-L/usr/local/opt/llvm/lib"
export CPPFLAGS="-I/usr/local/opt/llvm/include"

RUBY_CONFIGURE_OPTS="--with-openssl-dir=$(brew --prefix [email protected])" rbenv install 3.0.3
