ruby - Rmagick - Gem::Ext::BuildError：错误：无法构建 gem 原生扩展

问题描述

我安装pkg-config并imagemagick：

brew install pkg-config imagemagick@6

Imagemagick 版本

identify -version
Version: ImageMagick 6.9.12-28 Q16 arm 2021-10-29 https://imagemagick.org

尝试安装 rmagick 时

gem install rmagick

我明白了

Building native extensions. This could take a while...

所以我创建了一个/opt/homebrew/Library/Homebrew/shims/mac/super/pkg-config/bin/包含符号链接的文件夹

ln -s /opt/homebrew/opt/pkg-config/bin/pkg-config pkg-config

现在，当尝试安装 rmagick 时，我得到：

指定我必须安装development tools，所以我检查了它是否已安装：

gcc -v

Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c++/4.2.1
Apple clang version 12.0.5 (clang-1205.0.22.11)
Target: arm64-apple-darwin20.6.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

我已经搜索了很长时间，发现了几个处理类似问题的主题，但没有一个可以帮助我......

你知道为什么这不起作用吗？

我正在使用Mac OSX 11.6，ruby 3.0.2p107

非常感谢
