rbenv install 2.7.1 在 Mac OS Catalina 上使用 home-brew 失败

Question

我这几天一直在尝试安装 ruby​​。

我安装了 home-brew 检查是否安装了 openssl@1.1。

我运行brew install rbenv 并按如下方式配置我的zsh，

local READLINE_PATH=$(brew --prefix readline)
local OPENSSL_PATH=$(brew --prefix openssl)
export LDFLAGS="-L$READLINE_PATH/lib -L$OPENSSL_PATH/lib"
export CPPFLAGS="-I$READLINE_PATH/include -I$OPENSSL_PATH/include"
export PKG_CONFIG_PATH="$READLINE_PATH/lib/pkgconfig:$OPENSSL_PATH/lib/pkgconfig"

# Use the OpenSSL from Homebrew instead of ruby-build
# Note: the Homebrew version gets updated, the ruby-build version doesn't
export RUBY_CONFIGURE_OPTS="--with-openssl-dir=$OPENSSL_PATH"

# Place openssl@1.1 at the beginning of your PATH (preempt system libs)
export PATH=$OPENSSL_PATH/bin:$PATH

# Load rbenv
eval "$(rbenv init -)"

# Extract the latest version of Ruby so you can do this:
# rbenv install $LATEST_RUBY_VERSION
export LATEST_RUBY_VERSION=$(rbenv install -l | grep -v - | tail -1)

当我尝试运行 rbenv install 2.7.1 时，我得到一个构建错误。说它不能要求 openssl@1.1。

我检查了它是否已安装并尝试了我能想到的一切。这是在 catalina 10.15 全新安装上测试的。 我重新格式化了我的电脑并安装了 Xcode 命令工具。

这里是日志。

任何帮助将不胜感激，我很生气。

Answer 1

ruby-build 会尽力下载并编译想要的 Ruby 版本，但有时由于未满足系统依赖关系而导致编译失败，或者编译成功但新的 Ruby 版本在运行时出现奇怪的失败。以下说明是我们对健全构建环境的建议。

macOS： 如果您还没有这样做，请安装 Xcode 命令行工具 (xcode-select --install) 和 Homebrew。那么：

可选，但推荐：

brew install openssl readline

使用 Homebrew OpenSSL（注意：不适用于 ruby​​

export RUBY_CONFIGURE_OPTS="--with-openssl-dir=$(brew --prefix openssl@1.1)"
rbenv install 2.6.5

所以我最终做的是安装了整个在线找到的 Xcode 包，而不是通过 App Store。这样做有助于解决我的问题。
