Ruby 安装由于缺少扩展而中止:openssl、readline、zlib 编译错误 [英] Ruby install aborted due to missing extensions: openssl, readline, zlib compilation error

问题描述

我使用的是 macOS Catalina.我正在尝试通过 rbenv 安装旧版本的 Ruby(1.9.3、2.1.2).但是，在尝试安装旧版本时，我不断收到以下错误.*安装 2.4 或更高版本时没问题.

I'm using macOs Catalina. I'm trying to install older version of Ruby (1.9.3, 2.1.2) via rbenv. However, I keep getting the errors below, when trying installing older version. *It was fine when installing 2.4 or newer.

我已经试过了

brew install openssl
brew install readline
brew install zlib

以及 brew 更新.我已经安装并更新了所有内容，但以下错误仍然不断出现.

as well as brew update. I have everything installed and up-to-dated but still the errors below keeps coming up.

我也试过用配置选项安装

I also did tried to install with configure option

RUBY_CONFIGURE_OPTS="--with-readline-dir=`brew --prefix readline` --with-openssl-dir=`brew --prefix openssl`" rbenv install 2.1.2

请告诉我如何解决这个问题.

Please let me know how I can fix this.

ruby-build:使用 homebrew 的 readline

推荐答案

1. ruby-build 需要 clang 11 安装旧版 ruby​​:GitHub 评论链接

1. ruby-build required clang 11 to install older version of ruby: GitHub comment link

1. 如果 clang 已经更新到 12，你需要先核对它:sudo rm -rf/Library/Developer/CommandLineTools (源GitHub评论)
2. 然后，从 官方 Apple Developers 网站(至少需要 免费的 Apple Developers帐户)

1. If clang is already updated to 12, you need to nuke it first: sudo rm -rf /Library/Developer/CommandLineTools (source GitHub comment)
2. Then, install Command_Line_Tools_for_Xcode_11.5.dmg for clang 11 from official Apple Developers's website (required at least Free Apple Developer Account)

确保在安装旧版本的 ruby 时选择 openssl 1.0

1. ruby-build 安装适当的 openssl，例如.2.1.2 构建
2. echo $RUBY_CONFIGURE_OPTS 以确保它为空或设置为使用 openssl@1.0
3. 如果 ruby-build 仍然选择 openssl 1.1，那么你可以明确地 brew install rbenv/tap/openssl@1.0 和 RUBY_CONFIGURE_OPTS=--with-openssl-dir=$(brew --prefix openssl@1.0)" (源 GitHub 评论)

1. ruby-build installs appropriate openssl, eg. 2.1.2 build
2. echo $RUBY_CONFIGURE_OPTS to ensure it's empty or set to use openssl@1.0
3. If ruby-build still picks openssl 1.1, then you may explicitly brew install rbenv/tap/openssl@1.0 and RUBY_CONFIGURE_OPTS="--with-openssl-dir=$(brew --prefix openssl@1.0)" (source GitHub comment)
