Catalyst 对 Perl 5.8.8 的支持

Question

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.
BEGIN failed--compilation aborted at /opt/madhan/lib/perl5/Catalyst/ScriptRole.pm line 7.
Compilation failed in require at /usr/lib/perl5/site_perl/5.8.8/Module/Runtime.pm line 313.
Compilation failed in require at /opt/madhan/lib/perl5/Catalyst/ScriptRunner.pm line 13.
        Catalyst::ScriptRunner::find_script_class("Catalyst::ScriptRunner", "testsite", "Server") called at /opt/madhan/lib/perl5/Catalyst/ScriptRunner.pm line 42
        Catalyst::ScriptRunner::run("Catalyst::ScriptRunner", "testsite", "Server") called at /opt/madhan/testsite/script/testsite_server.pl line 8

perl 5.8.8 会支持 Catalyst MVC 吗？

Answer 1

这是 Catalyst 中的错误。 Catalyst::ScriptRole(自 2012 年以来!)中有一些类型检查代码已完全损坏，但损坏仅在特定情况下可见——即，如果脚本向 Catalyst 提供了 loader_class: :ScriptRole 不是已经加载的类(可能从来没有人加载过)，或者如果系统有一个非常旧的 UNIVERSAL.pm 版本例如 perl 5.8 附带的那个。这是您遇到的第二种情况。

我已经为 Catalyst-Runtime 推送了一个补丁来解决这个问题； 希望它能尽快发布它包含在Catalyst-Runtime 5.90115中.
