‘/usr/local/lib64/perl5’: No such file or directory

先日､CentOS 7にlogwatchをインストールしてrangeにて集計期間の設定方法を記事にしました｡

logwatch option –range (集計期間)

全く気にしていなかったのですが､これはDate::Manip perlモジュールがインストールしてあれば’date1 and date2’ができるとのことです｡

そこでインストールしてあるPerlモジュールはどう調べるの? どうもfindで検索するようです｡

いままでもエラーが表示されて気にはなっていたので解決しようと調べてみました｡

find: ‘/usr/local/lib64/perl5’: No such file or directory
find: ‘/usr/local/share/perl5’: No such file or directory

エラーは単純でフォルダが無いと言っているだけなんですが､PerlはCentOS 7インストール時のままです｡

3.3.11.2. インストール

CPAN からのモジュール
perl-CPAN パッケージが提供する cpan ツールを使用して CPAN Web サイトから直接モジュールをインストールします。これは /usr/local/share/perl5 と、32 ビットアーキテクチャーの場合は /usr/local/lib/perl5 に、64 ビットアーキテクチャーの場合は /usr/local/lib64/perl5 にインストールされます

CPANでPerlモジュールをインストールした場合に/usr/local/share/perl5,/usr/local/lib64/perl5に保存されるようです｡
CPANでPerlモジュールをインストールしない限りこのフォルダは作成されなくてエラーが毎回表示されることになるのか｡

設定されているPerlのパスを削除してもいいかも知れませんが､そうなると実際にCPANでインストールしても利用できないことになります｡

それならば取り敢えず
mkdir /usr/local/lib64/perl5
mkdir /usr/local/share/perl5
でエラーは回避できそうですが､折角なのでCPANの勉強も兼ねてインストールしてみます｡

1. perl-CPAN インストール

この時にはまだ二つのフォルダは作成されません｡
