我只是試圖運行一個簡單的Perl程序從XML導入數據並將其導出到數據庫。CPAN在Ubuntu上給出各種錯誤
使用Mysql;沒有工作，所以我沒有從cpan獲取Mysql.pm之後使用了DBD :: mysql。
但是，我無法安裝任何東西。我正在嘗試安裝xml解析器模塊，但無論您嘗試安裝哪個模塊，cpan都會給出這些錯誤。
install xml::parser

我做錯了什麼？我試圖尋找這些錯誤，但沒有人有正確的解決方案。我應該改變配置中的設置嗎？
如果您正在安裝系統Perl，您必須在sudo下運行cpan。如果你設置一個perlbrew Perl並將你的模塊安裝到本地Perl，那麼問題就會消失。 – DavidO
嘗試刪除似乎已損壞的'/ root/.cpan/sources/modules/02packages.details.txt.gz'，然後重試。如果這也行不通，我會按照下面的Arjuna Del Toso的建議。 – salva
@DavidO：不，你只需要在mbuild_install_build_command和make_install_make_command中有CPAN配置包括sudo。但看起來他已經以root身份運行了。 – ysth
