嘗試使用cpan安裝Perl模塊時，為什么會出現“找不到404”和“無法更改目錄”錯誤？
[英]Why do I get “404 Not Found” and “Failed to change directory” errors when I try to install a Perl module with cpan?
問題描述

我嘗試了多個鏡像，但是它們都給出相同的錯誤。 我怎樣才能解決這個問題？
2 個解決方案
解決方案1
8 2016-05-25 19:19:28
嘗試將命令從cpan Capture/Tiny更改為cpan Capture::Tiny 。 如果失敗，請從此處下載壓縮包，然后運行cpanm Capture-Tiny-0.40.tar.gz
解決方案2
4 已采納 2016-05-25 22:17:35
你跑了：
cpan Capture/Tiny
# ^-- notice the slash
斜線告訴cpan在指定路徑下查找分發文件。 在這種情況下， cpan通過作者Capture搜索分發文件Tiny 。 這個不存在，因此下載失敗。
通過傳遞路徑（ Foo/Bar ）而不是模塊名稱（ Foo::Bar ），可以安裝特定版本的發行版 。 要安裝開發版本的Capture-Tiny-0.41-TRIAL ，請運行：
cpan DAGOLDEN/Capture-Tiny-0.41-TRIAL.tar.gz
但是您可能只想安裝Capture :: Tiny的最新非開發版本，因此應該運行：
cpan Capture::Tiny
