Succeeded with the command below.

RUBY_CFLAGS=-DUSE_FFI_CLOSURE_ALLOC rbenv install 2.6.6

[vinamelody]

this doesn't work for 2.6.9

[vmdig]

this doesn't work for 2.6.2

[wstrzyz]

Didn't work for 2.6.0

[cbrecabarren]

Worked for 2.6.1

[wstrzyz]

I had the same issue but with 2.6.0

The solution that worked for me was:
CFLAGS="-Wno-error=implicit-function-declaration" RUBY_CONFIGURE_OPTS='--with-readline-dir=/usr/local/opt/readline/' arch -x86_64 rbenv install 2.6.0
