PREVIOUS VERSION

Previous version of App::Virtualenv has include PiV(Perl in Virtual environment) to list/install/uninstall modules using CPANPLUS API. Aimed with PiV making a package manager like Python pip. But Perl has various powerful package tools mainly CPAN and cpanminus, CPANPLUS and etc. And also building a great package manager requires huge community support. So, PiV is deprecated in version 2.xx.

You should uninstall previous version before upgrading from v1.xx: cpanm -U App::Virtualenv; cpanm -i App::Virtualenv;
