cpan and cpanm does not exist on PATH

after install perl, and cpanminus

cpan is in /usr/bin/core_perl
cpanm is in /usr/bin/vendor_perl.

so when I use them, I get
bash: cpan: command not found

Re: cpan and cpanm does not exist on PATH

You need to log back in so the profile scripts are sourced (or just source them manually).

EDIT: this is assume it's an archlinux system.  Is this still on your Manjaro laptop?

It's arch, I accessed docker container and install them.

I thought pacman have to make symbolic link for them on $PATH.

source? I did not add those paths to $PATH

Read the PKGBUILD: you don't need to manually add them.

pacman does not even know your $PATH, not to mention being able to do anything based on it. However, the package contains a file that should set your $PATH to the right value: it will be sourced automatically. Have you, as Trilby asked, logged out and in again? If your profile script is properly written and this is Arch, it should work.

Re: cpan and cpanm does not exist on PATH

UM.... It's docker container so I can't log out and in

PKGBUILD is also relevant installing by 'pacman -S'?

Re: cpan and cpanm does not exist on PATH

Please include some reference to docker in your topic title, since the problem seems to be stemming from that.

How are you running the docker container? Why are you trying to run cpan in a container? What is your end goal?

Mod note: Not a pacman issue, moving to NC.

Aaaand, this is exactly why I phrased my proper solution as a conditional either, or:

... or just source them manually

If you don't know how to source a profile snippet then you should not be using arch for your docker image.

Or more broadly, if you have no idea how arch linux works, having never installed it, you should not use it in a docker image.  And if you do there is no way we can actually help you via a web forum which is precisely why we have the community guideline that we can't / don't support such efforts here.

I'm about to build docker image that can be container running perl web server.

So I'm testing build to make image having bins(cpan or cpanm) that I need to install perl module

If you don't know how to source a profile snippet then you should not be using arch for your docker image.

I agree that... :< I have to learn docker and arch

If you build the image, then test it by entering the built image, it should work fine, no?

Your problem would only manifest if you're using the same docker shell session to install perl *and* run its programs.

Re: cpan and cpanm does not exist on PATH

Why do you have to?  Use a docker image of an OS you're more familiar with.

If you really do want to learn *both*, that's a respectable goal, but flailing with both at the same time is not a productive way to learn.  This is especially the case for arch linux.  If you want to learn to use arch linux, install arch linux.

Given that you have not installed arch, I'm really not sure why this thread is still open as it goes against our forum rules.  But I guess the moderators see it differently.  As I see it, we can support arch in a VM given that one installs arch in a VM, but if one inherits a VM image with arch pre-installed/configured, then we woud not (and by precedent do not) support that.  I don't see how this is any different.
