cpan模塊安裝失敗，沒有缺少先決條件-有解無憂

只是試圖安裝一個 CPAN 模塊，似乎沒有缺少任何先決條件，并且似乎找不到任何指向我需要做些什么來解決這個問題。有人可以理解問題可能是什么嗎？除非我絕對確定它可能只是測驗的問題，否則我寧愿不強制安裝。我查看了以前的問題，問題幾乎總是缺少 prereq 模塊，但這里似乎并非如此。

uj5u.com熱心網友回復：

XML-Liberal-0.30 中有兩個錯誤。

不建議強制安裝模塊。

這將安裝發行版：

wget https://cpan.metacpan.org/authors/id/M/MI/MIYAGAWA/XML-Liberal-0.30.tar.gz
tar xvzf XML-Liberal-0.30.tar.gz
cd XML-Liberal-0.30
perl -pe's/mandate/mandates?/' -i~ lib/XML/Liberal/Remedy/StandaloneAttribute.pm
perl -pe's/->extract_error\(\K\$\@/"\$\@"/' -i~ lib/XML/Liberal.pm
perl -I . Makefile.PL
make test
make install

模塊的邏輯基本如下：

默認情況下最多 15 次：
1. 嘗試在捕獲錯誤時使用 XML::LibXML 決議檔案。
2. 如果沒有發生錯誤，
  1. 成功（回傳）
3. 對于每條錯誤訊息，
  1. 對 XML 應用修復以嘗試解決錯誤。
失敗。

手頭的問題是 libxml2 更改了它的一些錯誤訊息。它曾經發出

parser error : Specification mandate value for attribute ...

但是語法錯誤是固定的。

parser error : Specification mandates value for attribute ...

修復很簡單。在 lib/XML/Liberal/Remedy/StandaloneAttribute.pm 中，替換

    my ($attr) = $error->message =~
        /^parser error : Specification mandate value for attribute (\w )/
            or return 0;

和

    my ($attr) = $error->message =~
        /^parser error : Specification mandates? value for attribute (\w )/
            or return 0;

(I'm assuming that some versions of libxml2 returned Specification mandate value. A web search seems to confirm this.)

The second issue is in how it parses error messages. I'm not exactly sure what the broken code is trying to do, but it can be worked around by replacing

my $error = $self->extract_error($@, \$xml);

with

my $error = $self->extract_error("$@", \$xml);

in XML/Liberal.pm.
