macOS 12.6（M1 Pro）下pyenv安装Python3.10遇特殊错误

我尝试使用pyenv安装Python 3.10.7，在遵循相关帖子的置顶解决方案后仍遇到以下错误：

解决思路 #

• 更新pyenv及python-build：你的python-build版本是20180424，过于老旧，先执行更新：

  brew update && brew upgrade pyenv
  

• 安装/更新依赖库：确保编译所需的依赖是最新版本

  brew install zlib openssl readline sqlite3 xz tcl-tk
  

• 配置环境变量，强制使用Homebrew依赖：
  在你的shell配置文件（~/.zshrc或~/.bashrc）中添加以下内容：

  export LDFLAGS="-L$(brew --prefix zlib)/lib -L$(brew --prefix openssl@1.1)/lib"
  export CPPFLAGS="-I$(brew --prefix zlib)/include -I$(brew --prefix openssl@1.1)/include"
  export PKG_CONFIG_PATH="$(brew --prefix zlib)/lib/pkgconfig:$(brew --prefix openssl@1.1)/lib/pkgconfig"
  

  保存后重新加载配置：

  source ~/.zshrc # 若使用bash则执行source ~/.bashrc
  

• 清理旧编译缓存并重新安装：

  rm -rf /var/folders/nm/zb8gvgds6nx448zw248vlg1c0000gn/T/python-build.20221025053833.56249
  pyenv install 3.10.7
  

• 若上述步骤无效，尝试直接指定zlib路径编译：

  PYTHON_CONFIGURE_OPTS="--with-zlib=$(brew --prefix zlib)" pyenv install 3.10.7
