在 mac osx 11.6 上安装 ruby​​ 2.6.x 和 3.0.x 时 ruby​​-install 失败

Question

运行 ruby​​-install 时，构建失败。rbenv 问题中也报告了这一点（https://github.com/rbenv/ruby-build/issues/1725）。

例如安装 ruby​​ 2.6.8 时

# installing via ruby-install ( https://github.com/postmodern/ruby-install )
ruby-install ruby 2.6.8

它会导致以下错误

ossl_x509store.c:452:30: note: ')' token is here
    result = rb_funcall(ctx, rb_intern("verify"), 0);
                             ^~~~~~~~~~~~~~~~~~~

看来是编译器的问题。首先确保 Xcode 已正确安装。就我而言，我已经安装了它，但您可以选择重新安装以确保。希望这可以帮助人们节省尝试找出问题的时间，因为编译需要几分钟。

# check xcode, should yield : /Library/Developer/CommandLineTools
xcode-select -p

# check xcode, should yield : xcode-select version 2384
xcode-select -v

# install xcode-select
xcode-select --install

# reinstall openssl and version 3
brew reinstall openssl@1.1

# install build dependancies
brew install openssl readline libyaml zlib bison bison@2.7

# ensure build is using bison
export PATH="$(brew --prefix bison@2.7)/bin:$PATH"

# set ruby compilation flags
export CFLAGS="-Wno-error=implicit-function-declaration"
export RUBY_CONFIGURE_OPTS="--with-openssl-dir=$(brew --prefix openssl@1.1) --with-readline-dir=$(brew --prefix readline) --with-libyaml-dir=$(brew --prefix libyaml) --with-zlib-dir=$(brew --prefix zlib)"

# install ruby via ruby-install
ruby-install ruby 2.6.8

如果失败则再执行几个步骤

# ensure that openssl is linked
brew unlink openssl && brew link openssl --force

# load openssl 1.1 for compilation
export LDFLAGS="-L/opt/homebrew/opt/openssl@1.1/lib"
export CPPFLAGS="-I/opt/homebrew/opt/openssl@1.1/include"
export PKG_CONFIG_PATH="/opt/homebrew/opt/openssl@1.1/lib/pkgconfig"

# install ruby via ruby-install
ruby-install ruby 2.7.7

当我运行以下命令时，我遇到了同样的问题：ruby-install ruby 2.6.8 -- --with-openssl-dir=$(brew --prefix openssl@1.1)。

我更新bison并brew install bison@2.7跑去export PATH="$(brew --prefix bison@2.7)/bin:$PATH"修复裂土器。然后，重新运行最初的 ruby​​ 命令就成功了！
