使用Perl 5.8.8支持Catalyst

Question

执行催化剂服务器脚本时面临以下问题.

Couldn't load class (Catalyst::Script::Server) because: "ensure_class_loaded" is not exported by the Catalyst::Utils module
Can't continue after import errors at /opt/madhan/lib/perl5/Catalyst/ScriptRole.pm line 7.
BEGIN failed--compilation aborted at /opt/madhan/lib/perl5/Catalyst/ScriptRole.pm line 7.

perl 5.8.8会支持Catalyst MVC吗？

Answer 1

这是Catalyst中的一个错误.Catalyst :: ScriptRole中有一些类型检查代码(自2012年以来!)完全被破坏,但破坏只在特定情况下可见 - 即,如果脚本提供的loader_classCatalyst :: ScriptRole还不是加载类(可能没有人),或者系统有一个非常旧版本的UNIVERSAL.pm,例如perl 5.8附带的版本.这是你遇到的第二种情况.

我已经将补丁推送到Catalyst-Runtime来解决这个问题; 希望它很快就会发布它包含在Catalyst-Runtime 5.90115中.
