Node编译
编译Node
node的编译都在BUILDING文档中列举了具体要求，在Macos章节的Building Nodejs里说明了如何编译。
问题1: V8编译错误
目测是因为c++版本问题. 试了下clang --version，电脑上装的是16，要求在configure文件里有，warn(f"C++ compiler (CXX={CXX}, {version_str}) too old, need g++ 12.2.0 or clang++ 19.1.0{' or Apple clang++ 17.0.0' if is_apple else ''}")
需要更新下clang
clang --version
Apple clang version 16.0.0 (clang-1600.0.26.6)
Target: arm64-apple-darwin25.0.0
Thread model: posix手动下一下llvm brew install llvm
配置环境变量

上一步下载了最新版llvm，结果太新，链接时用的macos系统的libc++，结果太老了没有这些符号。降低一下llvm版本(llvm@19)。

ld: symbol(s) not found for architecture arm64问题3: flag配置问题
又遇到了问题1的问题，不过不是clang问题了，而是没配c++20导致的，node最新版要求c++20。export CXXFLAGS="-std=c++20"解决
学习过程
./configure --debug是做什么的
运行这个文件，主要会(1)检查系统环境，例如python/clang等编译器环境是否支持;(2)生成构建配置config.gypi文件;(3)调试模式的调试符号等;(4)根据平台配置V8等子模块。
