install virtualenv

To install virtualenv in Perl, you can use the cpanm command, which is a package manager for Perl modules. Here are the steps:

1. Open your terminal or command prompt.
2. Run the following command to install cpanm if you don't have it installed already: curl -L https://cpanmin.us | perl - --sudo App::cpanminus
3. Once cpanm is installed, you can use it to install virtualenv by running the following command: cpanm virtualenv

That's it! virtualenv should now be installed on your Perl environment.

Please note that the above instructions assume you have Perl and the necessary dependencies already installed on your system.
