我正在开发一个需要Event :: Lib的Perl项目。我在MacOS 10.7上，正在运行Citrus Perl而不是系统Perl。我从源代码安装了libevent，编译得很好。但是，当我去安装Event :: Lib时，我遇到了一些错误：
cp Lib/Event/Lib.pm blib/lib/Event/Lib.pm

有没有人对下一步尝试有什么想法？
编辑：在尝试了一些'o conf'选项之后：
cpan[1]> o conf makepl_arg "INC=-I/usr/local/include LIBS=-L/usr/local/lib -levent"
makepl_arg [INC=-I/usr/local/include LIBS=-L/usr/local/lib -levent]
Your /Users/username/code/CitrusPerl/vendor/lib/CPAN/Config.pm file
is not writable. I will attempt to write your configuration to
/Users/username/.cpan/CPAN/MyConfig.pm instead.
Old configuration file /Users/username/.cpan/CPAN/MyConfig.pm
moved to /Users/username/.cpan/CPAN/MyConfig.pm.bak

答案 0 :(得分：0)
我能够在大约10分钟的时间内完成这项工作。
然后：
我认为以上是提供适当开发环境的最佳实用工具，您可以切换; IE你可以切换飞的Perl版本。此外，它们不会影响您的原生系统。无论如何，如果您决定不使用前面提到的，您的特定错误看起来是关于丢失的头文件。我断言libevent头确实在/ usr / local / include。
祝你好运。
