Problems using LWP::Protocol:https under macOS Catalina

Question

When I run a program using LWP::UserAgent (that worked until now) I get the error message

501 Protocol scheme 'https' is not supported (LWP::Protocol::https not installed)

But when I run cpan it says LWP::Protocol::https is installed:

cpan[1]> install LWP::Protocol::https

LWP::Protocol::https is up to date (6.09).

What can I possibly be doing wrong?

Answer 1

I solved the problem by installing Net::SSLeay and IO::Socket::SSL .

A pity LWP::Protocol::https cannot emit a warning asking the user to install those two…
