與DateTime :: Format :: ISO8601 Perl的問題跟蹤問題與Params ::驗證？

Question

希望有人可以對此有所瞭解...

我和團隊中的許多其他開發人員在內部perl應用程序運行時都有很大的規模。儘管這一切都運行良好，橫跨每個人的筆記本電腦（Linux和Mac的），我不能在我的生活中在我的大PC上運行在家裏。

我已經安裝了通過CPAN所有的依賴，但訪問該網站時，我得到在Apache的錯誤日誌如下：

The 'regex' parameter ("(?x-ism:^ (\d{4}) (\d\d) (\d\d) $)") to DateTime::Format::Builder::Parser::create_single_parser was an 'unknown', which is not one of the allowed types: scalarref

我堅持一些諾迪print STDERR的直接在ValidatePP.pm所以如果你正在尋找的行號，他們是輕微的，但基本上在ValidatePP.pm它越來越下面的代碼塊中sub _get_type：

# I really hope this never happens. 
return UNKNOWN; 

如果有幫助，運行一個perl -v返回弗洛這個PC

上翼版這是Perl 5中，12版，顛覆4（v5.12.4）爲 x86_64的Linux的GNU的線程多

有人建？

UPDATE：

如果有幫助，子程序_get_type基本上決定（使用UNIVERSAL::isa），其regex: !!perl/regexp (?x-ism:^ (\d{4}) (\d\d) (\d\d) $)不是一個如果滿足以下：

my %isas = (
     'ARRAY' => ARRAYREF, 
     'HASH' => HASHREF, 
     'CODE' => CODEREF, 
     'GLOB' => GLOBREF, 
     'SCALAR' => SCALARREF, 
    ); 

Answer 1

首先，您使用的是最新版本Params::Validate（和所有其他模塊）？ 按照changelog有P中的一些錯誤:: V 1.01：

1.02 2012-02-06

• 以前的版本不會被裝載的XS執行，即使它已經 編譯。

• 隨着Perl的更新版本的出現，純Perl的實現以不同於XS實現的方式處理對象的正則表達式 對象。爲了向後兼容，它們應該被視爲屬於SCALARREF類型的 。

• 這兩個錯誤組合在CPAN上設法打破了許多 模塊的測試套件。這個版本應該修復它們。
