在macOS 13.0.1（Rosetta环境）下用pyenv安装Python3.7.3失败求助

执行pyenv86 install 3.7.3时出现构建失败，错误提示：

BUILD FAILED (OS X 13.0.1 using python-build 20180424)

日志详情：

checking for clang++... no
configure:

  By default, distutils will build C++ extension modules with "clang++".
  If this is not intended, then set CXX on the configure command line.

checking for the platform triplet based on compiler characteristics... darwin
configure: error: internal configure error for the platform triplet, please file a bug report
make: *** No targets specified and no makefile found.  Stop.

环境配置信息 #

• 当前终端架构：

$ arch 
i386

• brew86别名配置：

$ which brew86
brew86: aliased to arch --x86_64 /usr/local/Homebrew/bin/brew

• pyenv86别名配置：

$ which pyenv86
pyenv86: aliased to arch -x86_64 pyenv

• PATH环境变量：

$ echo $PATH
/opt/homebrew/bin:/Users/abhinavmulagada/.pyenv/shims:/opt/homebrew/bin:/opt/homebrew/sbin:/usr/local/bin:/System/Cryptexes/App/usr/bin:/usr/bin:/bin:/usr/sbin:/sbin

• ~/.zshrc配置内容：

# rosetta setup
if [ $(arch) = "i386" ]; then
        alias brew86='arch --x86_64 /usr/local/Homebrew/bin/brew'
        alias pyenv86="arch -x86_64 pyenv"
fi

# pyenv
if command -v pyenv 1>/dev/null 2>&1; then
    eval "$(pyenv init -)"
fi

path=('/opt/homebrew/bin' $path)
export PATH

解决建议 #

• 手动指定clang++路径：从日志看系统无法找到clang++，安装时直接指定CXX环境变量指向系统默认的clang++：

  CXX=/usr/bin/clang++ pyenv86 install 3.7.3
  

• 调整PATH优先级：当前PATH中ARM版Homebrew路径（/opt/homebrew/bin）排在X86版（/usr/local/bin）之前，可能导致依赖调用错误。修改~/.zshrc中的PATH配置：

  path=('/usr/local/bin' '/opt/homebrew/bin' $path)
  export PATH
  

  执行source ~/.zshrc使配置生效。
• 更新python-build组件：当前使用的python-build版本为20180424，版本过旧存在兼容性问题，通过X86版brew更新pyenv：

  brew86 update && brew86 upgrade pyenv
  

• 安装Xcode命令行工具（X86架构）：确保Rosetta环境下有完整的编译工具：

  arch -x86_64 xcode-select --install
  

  安装完成后重启终端再尝试安装。
