How to install properly?

xeruf commented 3 years ago

After installing it on Arch Linux, regardless of via CPAN or directly through the script and running the binary, I get the following error:

Cannot load Algorithm::Diff:

I have zero experience with Perl, what am I supposed to do?

Tux commented 3 years ago

$ cpan Algorithm::Diff

This program only works with its prerequisites installed. The correct (easy) way to install ccdiff is (or should be)

$ cpan App::ccdiff

If that doesn't work, I'm curious to what the error messages are

oooww, there is a truckload of information in this log:

The current configuration of allow_installing_outdated_dists is 'ask/no', but for this option we would need 'CPAN::DistnameInfo' installed. Please install 'CPAN::DistnameInfo' as soon as possible. As long as we are not equipped with 'CPAN::DistnameInfo' this option does not take effect

Not vital, but it will likely make your installations more smooth if you install CPAN::DistnameInfo

So, you are trying to install as a normal user into the system space. Unless you use sudo this won't (and shouldn't) work. You've got several options here:

install the package from your system distribution, sumething like suse$ sudo zypper install perl-Algorithm-Diff centos$ sudo yum install perl-Algorithm-Diff
run the cpan command as root using sudo. (not advicable if the module is avail;able as system package)
install in your own working tree and set $PERL5LIB to match it
use perlbrew: it'll cost you time to set it up, but it might be rewarding later on
run as root using sudo
install in your own working tree and set $PERL5LIB to match it
use perlbrew: it'll cost you time to set it up, but it might be rewarding later on

The same error applies to installing Capture::Tiny suse$ sudo zypper install perl-Capture-Tiny centos$ sudo yum install perl-Capture-Tiny

As these two prerequisites failed to install, App::ccdiff won't install. All prereqs have to be met.

See, I have no clue concerning Perl :) thank you!

On arch I needed sudo pacman -S perl-algorithm-diff perl-capture-tiny, and it works now :)

So CPAN can't install into the userspace (i.e. ~/.local/bin)? I guess gonna do it manually then, and maybe I'll get around to creating an AUR package :)

Tux commented 3 years ago

To use a local environment, use cpan -I, but cpan is not as well suited for this as cpanm is.

$ cpanm --help |& grep -i -e local -e bin -e lib
  -l,--local-lib            Specify the install base to install modules
  -L,--local-lib-contained  Specify the install base to install all non-core modules
  cpanm ~/dists/MyCompany-Enterprise-1.00.tar.gz            # install from a local file
  cpanm .                                                   # install from local directory
  cpanm -L extlib Plack                                     # install Plack and all non-core deps into extlib

You can read all about the differences and alternatives here and the docs for cpanm here
