执行催化剂服务器脚本时遇到以下问题。

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.

perl 5.8.8是否支持Catalyst MVC？

Answer 1

这是Catalyst中的一个错误。在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，如果脚本向Catalyst :: ScriptRole提供了loader_class如果系统有一个非常旧版本的UNIVERSAL.pm，例如perl 5.8附带的版本，那么它还不是一个已加载的类（可能没有人有），或。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。

使用Perl 5.8.8支持Catalyst
