Perlにコアモジュールがありません

Perlにコアモジュールがありません

Ubuntu 20.04で数日前にうまく機能していたBuildrootを使用すると、次のエラーメッセージが表示されます。

Your Perl installation is not complete enough; at least the following modules are missing:

     Data::Dumper
     ExtUtils::MakeMaker
     Thread::Queue
     Math::BigInt
     Math::BigRat

実行すると、perl -V次のようになります。

Can't locate Config.pm:   /usr/local/lib/x86_64-linux-gnu/perl/5.30.0/Config.pm: Permiso denegado.
BEGIN failed--compilation aborted.

私のシステムに「/usr/local/lib/x86_64-linux-gnu」フォルダがありません(/usr/libにあります)。

私の考えでは、これが失敗したビルドとインストールの試みに関連している可能性があると思います。 /usr/localサブフォルダにサードパーティの依存関係をインストールしようとしたときに昨日試しましたが、最終的に/usr/localの下にファイルがありませんでした。 (cc1plus: error: /usr/local/include/x86_64-linux-gnu: Permission denied実際の問​​題は次のとおりです。許可なしにフォルダは存在しません)。

それが私のシステムをどのように台無しにしたのかわかりません。 Perlの問題はこれまで私が見つけた唯一の副作用であり、問​​題を解決する方法に関する有用な情報を見つけることができません。

'apt'を使用してPerlとその依存関係(perl-base、perl-modulesなど)を再インストールしてみましたが、成功しませんでした。

を実行するとperl -Vいくつかsudoの情報があるので、役に立つ場合に備えてここに貼り付けます。

実際、これは最終的に権限の問題です。何らかの理由でフォルダの権限が変更され/usr/local/includeました/usr/local/lib。これを復元すると755問題が解決します。

sudo chmod 755 /usr/local/lib
sudo chmod 755 /usr/local/include
