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

Question

当运行ruby-install时，它无法构建。这也在rbenv issues (https://github.com/rbenv/ruby-build/issues/1725)中报告了。

例如，在安装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);
                             ^~~~~~~~~~~~~~~~~~~

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

我用brew install bison@2.7更新了bison，并运行export PATH="$(brew --prefix bison@2.7)/bin:$PATH"来修复ripper。然后，重新运行初始的ruby命令起作用了！

似乎是编译器的问题。首先，确保正确安装了xcode。在我的例子中，我之前已经安装了它，但你可以选择重新安装以确保。希望这能帮助人们节省时间来解决这个问题，因为编译它需要几分钟。

# 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

我不能通过编译在Big Sur上安装任何红宝石。我明白了：
