问题描述

刚换了搭载Apple M2芯片的新设备，打算创建Rails新项目，但执行bundle install时总是报错，具体错误如下：

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

    current directory: /Users/a1111/RubymineProjects/FasterThanLightTest/FasterThanLightTest/vendor/cache/ruby/3.0.0/gems/racc-1.6.2/ext/racc/cparse
/Users/a1111/.rvm/rubies/ruby-3.0.0/bin/ruby -I /Users/a1111/.rvm/rubies/ruby-3.0.0/lib/ruby/3.0.0 -r ./siteconf20230227-63071-piv0lx.rb extconf.rb
checking for rb_block_call()... no
checking for rb_ary_subseq()... no

后续还会出现以下提示：

An error occurred while installing racc (1.6.2), and Bundler cannot continue.
Make sure that `gem install racc -v '1.6.2' --source 'https://rubygems.org/'` succeeds before bundling.

已安装最新版Xcode命令行工具，当前Ruby版本3.0.0，Rails版本7.0.4，请问问题原因是什么？

问题原因分析

Ruby版本与Apple Silicon架构兼容性不足：Ruby 3.0.0发布早于Apple M2芯片，官方预编译包未针对ARM64架构优化，编译racc这类原生扩展时，会出现核心函数（如rb_block_call()、rb_ary_subseq()）检测失败的情况。
RVM编译Ruby时架构参数缺失：若通过RVM安装Ruby 3.0.0，编译过程中未明确指定ARM64架构，生成的Ruby二进制文件无法适配M2芯片的系统函数，进而阻碍原生gem的编译。
racc版本适配问题：racc 1.6.2存在与ARM64架构下Ruby 3.0.0的兼容性bug，部分依赖的Ruby核心函数在该环境下无法被正确识别，导致编译失败。
