Ich versuche gerade, ein einfaches Perl-Programm auszuführen, um Daten aus xml zu importieren und sie in eine Datenbank zu exportieren.
Use Mysql; hat nicht funktioniert, also habe ich stattdessen DBD::mysql verwendet, nachdem ich Mysql.pm nicht von cpan bekommen konnte.
Ich kann jedoch nichts installieren. Ich versuche, xml-Parser-Modul zu installieren, aber cpan gibt diese Fehler, egal welches Modul Sie versuchen, zu installieren.
install xml::parser

Wenn Sie Perl als System installieren, müssen Sie cpan unter sudo ausführen. Dieses Problem verschwindet, wenn Sie ein perlbrew Perl einrichten und Ihre Module in Ihr lokales Perl installieren.

Versuchen Sie zu entfernen
/root/.cpan/sources/modules/02packages.details.txt.gzdie beschädigt zu sein scheint, und versuchen Sie es erneut. Wenn auch das nicht funktioniert, würde ich den Rat von Arjuna Del Toso unten befolgen.2 Stimmen
@DavidO: nein, man muss nur in der CPAN-Konfiguration sudo in mbuild_install_build_command und make_install_make_command einfügen. Aber es sieht so aus, als ob er bereits als Root läuft.
