无法在Perl中找到DBI.pm模块 [英] Unable to locate DBI.pm module in Perl

问题描述

我使用的是CentOS，我已经安装Perl 5.20和Perl 5.10默认存在。

I am using CentOS, and I have installed Perl 5.20 and Perl 5.10 was present by default.

我使用Perl 5.20版本来执行Perl代码

我试图使用DBI模块并收到此错误

I am trying to use the DBI module and get this error

[root@localhost ~]#perl -e 'use DBI;'
Can't locate DBI.pm in @INC (you may need to install the DBI module) (@INC contains: /usr/local/lib/perl5/site_perl/5.20.1/i686-linux /usr/local/lib/perl5/site_perl/5.20.1 /usr/local/lib/perl5/5.20.1/i686-linux /usr/local/lib/perl5/5.20.1 .) at -e line 1.

    • 正如Sobrique在注释中建议的，你不应该触摸系统perl。我建议您使用 perlbrew 。使用perlbrew你可以从本地用户安装不同版本的perl，并使用perlbrew检查perl的所有安装版本只是 $ perlbrew -l <​​/ code>。
    
    
    • As Sobrique suggested in comments, you should never touch system perl. I'd suggest using perlbrew. With perlbrew you can install different versions of perl from local user, and to check all installed versions of perl using perlbrew just do $ perlbrew -l.

    安装多个perls

    $ perlbrew -v install perl-5.20.0
    $ perlbrew -v install perl-5.13.4
    

    在他们之间切换

    $ perlbrew switch perl-5.20.0
    $ perlbrew switch perl-5.13.4
    

    有关详细信息，请参阅此文章：使用App :: perlbrew和App :: cpanminus安装多个Perls
