ruby-install 无法在 m1 mac pro 上安装旧版本的 ruby，例如 2.7.7

make: *** [do-install-all] Error 1
!!! Installation of ruby 2.7.7 failed!
问题与openssl的版本有关。旧版本的 ruby 不支持新版本的 openssl
要修复请尝试以下方法
# reinstall openssl and version 3
brew reinstall [email protected]
# install build dependancies
brew install openssl readline libyaml zlib bison [email protected]
# ensure build is using bison
export PATH="$(brew --prefix [email protected])/bin:$PATH"
# set ruby compilation flags
export CFLAGS="-Wno-error=implicit-function-declaration"
export RUBY_CONFIGURE_OPTS="--with-openssl-dir=$(brew --prefix [email protected]) --with-readline-dir=$(brew --prefix readline) --with-libyaml-dir=$(brew --prefix libyaml) --with-zlib-dir=$(brew --prefix zlib)"
# ensure that openssl is linked
brew unlink openssl && brew link openssl --force
# load openssl 1.1 for compilation
export LDFLAGS="-L/opt/homebrew/opt/[email protected]/lib"
export CPPFLAGS="-I/opt/homebrew/opt/[email protected]/include"
export PKG_CONFIG_PATH="/opt/homebrew/opt/[email protected]/lib/pkgconfig"
# install ruby via ruby-install
ruby-install ruby 2.7.7
我对略有不同但相关问题的其他答案可以找到：在 mac osx 11.6 上安装 ruby 2.6.x 和 3.0.x 时，ruby-install 失败
