首先我想构建 DBD::mysql包裹。这一直失败，因为无法为带有 Symbol not found: _is_prefix 的测试加载导致的任何结果。所以我认为 cpan 可能有点旧。我知道这是一个随机假设，但 cpan 确实告诉我安装最新的 Bundle::CPAN .

谁成功安装了 DBD::mysql或 Bundle::CPAN在 Mac OS X 10.5 上？你能推荐我可以做的不同的事情吗？

This is perl, v5.8.8 built for darwin-thread-multi-2level
(with 4 registered patches, see perl -V for more detail)

/usr/local/mysql/bin/mysql  Ver 14.14 Distrib 5.1.36,
for apple-darwin9.5.0 (i386) using readline 5.1

这是 DBD::mysql 的 CPAN 输出日志:

最佳答案

好的，如果您遇到这些错误，我现在知道以下内容:

1. MySQL 5.1 for Mac OS X x86_64 与 DBD::mysql 不兼容(目前)。安装 32 位 x86 版本，然后重试。你会成功的。我希望 perl Makefile.pl 会在横幅中告诉您。
2. Bundle::CPAN 有问题，因为我没有以 root 身份安装。为什么它会报告循环引用而不是安装权限问题，我永远无法理解。

如果此信息已过时，请添加评论。
