问题描述
当clang --version
为12或更高时,低于2.3.1的Ruby版本无法安装。要重现该问题,请首先通过软件更新获得xcode命令行开发人员工具版本12或擦除Mac并安装自制软件:
# homebrew installs version 12 of the command line developer tools as well
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
然后这失败了:
brew install rbenv
rbenv install 2.2.5
rbenv install 2.2.5的输出:

解决方法
这与Xcode 12版本(2020年9月16日)不符。要“解决” /解决该问题,如果您已经clang --version
报告了第12版点,您可以sudo rm -rf /Library/Developer/CommandLineTools
然后转到https://developer.apple.com/downloads/,使用您的Apple ID登录,然后找到“用于Xcode 11.5的命令行工具”或类似的工具。一旦clang --version
报告了11个点,这应该会再次起作用:rbenv install 2.2.5
此变通办法最初是由bfreezy在https://github.com/rbenv/ruby-build/issues/1353处发现的。
, Burnettk关于将Xcode CommandLineTools更改为低于12的版本是正确的,但是无需删除/Library/Developer/CommandLineTools
,如果您每天使用Xcode,这很可能在您的环境中导致其他问题。
首先,打开Xcode并转到Preferences > Locations
,然后检查Command Line Tools
下拉菜单中的哪些选项。如果可用,请选择Xcode 11.x
,然后重试安装。

如果尚未提供该版本,请从https://developer.apple.com/downloads/安装低于12.0的“命令行工具”的最大版本。完成后,跳回到“位置”首选项,然后选择刚刚安装的工具,然后重新进行Ruby安装。
