cpanApp::cpanminus失敗并出現多個錯誤：“放棄決議您的/Users/foo/.cpan/sources/modules/02packages.details.txt.gz，錯誤太多”

我正在嘗試使用cpan App::cpanminus. 我收到以下錯誤。如何修復錯誤并安裝模塊？

在我看來，嘗試使用多種方法下載檔案，但都失敗了，讓您沒有檔案或檔案為空。

這表明存在網路問題。您需要修復網路問題才能繼續。也許您需要使用不同的鏡像，或者可能需要指導下載者使用代理。

請注意，您可以洗掉該檔案，從而強制再次嘗試下載它。

更新：我檢查了您cpan配置為使用 ( http://mirrors.ccs.neu.edu/CPAN)的 URL 的有效性，它很糟糕。名稱mirrors.ccs.neu.edu無法決議。因此，您需要配置cpan為使用不同的鏡像。

要告訴cpan使用其他東西，請運行cpan。從內部，使用o conf init urllist或o conf urllist http://www.cpan.org/。不要忘記o conf commit在退出前使用( quit)保存設定。

你也可以使用類似的東西

printf '%s\n%s\n' 'o conf urllist http://www.cpan.org/' 'o conf commit' | cpan

更新：盡管下面的答案對我有用，但我后來了解到一個更好的答案，以及對根本原因的正確解釋。請參閱上面來自池上的答案，了解首選和接受的方法。出于歷史目的保留以下答案，因為它也有效。

錯誤的原因是該檔案02packages.details.txt.gz和/或可能的其他檔案已損壞。將.cpan目錄移動到新位置并再次重新運行該命令。它現在應該可以作業了。

cd && mv .cpan .cpan-bak
cpan App::cpanminus

印刷：

CPAN.pm requires configuration, but most of it can be done automatically.
If you answer 'no' below, you will enter an interactive dialog for each
configuration option instead.

Would you like to configure as much as possible automatically? [yes]

這個確認的作業解決方案是從Arjuna Del Toso 的這個答案復制到類似問題的，所有的功勞都應該歸于誰。我將它張貼在這里，以便搜索此錯誤訊息會導致此頁面具有有效的解決方案。
