Well, I just found that I can install it by MIME::Decoder::Base64, however, why does the problem exist ? What can I do if I see these loop-back error occur ? ----- Original Message ----- From: "Connie Chan" <unknown@reborn.org> To: <beginners@perl.org> Sent: Monday, April 01, 2002 5:20 AM Subject: Module Install problem Dear all, I have a problem for installing module MIME::Base64. I am using ActiveState Perl on Win32 OS. When I try to use ppm "install MIME::Base64", I got : Error installing package 'MIME-Base64': Could not locate a PPD file for package MIME-Base64 When I try to use ppm3, "install MIME::Base64", I got : Error: package 'MIME-Base64' is already installed. Use 'upgrade'. When I try ppm3, "upgrade MIME::Base64", I got : Error: package 'MIME' is not installed. I've checked lib and site/lib both, no MIME has existed. So what's my problem ? Is that any registry table under perl ? so I have to remove it by myself ? Thank you very much for any advice, ConnieThread Previous
