Mac系统git svn clone报错SVN::_Core模块加载失败怎么解决？

错误详情 #

完整报错日志如下：

Can't load '/usr/local/opt/subversion/lib/perl5/site_perl/5.30.3/darwin-thread-multi-2level/auto/SVN/_Core/_Core.bundle' for module SVN::_Core: dlopen(/usr/local/opt/subversion/lib/perl5/site_perl/5.30.3/darwin-thread-multi-2level/auto/SVN/_Core/_Core.bundle, 0x0001): Symbol not found: _apr_crypto_block_cleanup

该错误核心原因是Homebrew安装的subversion依赖的apr-util库和系统自带版本不匹配，subversion需要的_apr_crypto_block_cleanup符号在系统自带的/usr/lib/libaprutil-1.0.dylib中不存在，导致SVN的Perl模块加载失败，进而git-svn无法运行。

修复步骤 #

• 第一步：卸载现有Homebrew安装的相关包，消除版本冲突

brew uninstall --force git subversion apr apr-util

• 第二步：清理Homebrew残留缓存和未使用的依赖

brew cleanup && brew autoremove

• 第三步：按顺序重新安装依赖

# 先安装apr和apr-util依赖
brew install apr apr-util
# 安装subversion
brew install subversion
# 安装git和git-svn组件
brew install git git-svn

• 第四步（仅M系列芯片Mac需要执行）：将Homebrew的Perl路径加入环境变量，避免调用系统版本Perl导致冲突
  打开~/.zshrc（zsh用户）或者~/.bashrc（bash用户），添加如下内容：

export PATH="/opt/homebrew/opt/perl/bin:$PATH"

保存后执行source ~/.zshrc或者source ~/.bashrc使配置生效。

验证修复结果 #

执行以下命令，正常输出版本信息即说明修复完成：

git svn --version

之后即可正常执行git svn clone操作。
