Zef throws `Type check failed for return value; expected IO::Path but got Any (Any)` when it can't find the `META6.json`

rawleyfowler commented 1 year ago

Context

I just installed Zef on a FreeBSD machine, with the newest build of Rakudo. Whenever I try to install a local module with zef install --force . I get the following type error:

Type check failed for return value; expected IO::Path but got Any (Any)

Expected Behavior

I expect it to install my local module.

Actual Behavior

It raises a type error.

Steps to Reproduce

$ zef install --force --debug .
Type check failed for return value; expected IO::Path but got Any (Any)

Your Environment

raku -v

Welcome to Rakudo™ v2022.07-101-g6cded78e9.
Implementing the Raku® Programming Language v6.d.
Built on MoarVM version 2022.07-24-gc1a163ba0.

zef list --installed

$ zef list --installed
===> Found via inst#/home/rf/.local/bin/rakudo/share/perl6/core
rakudo:ver<2022.07.101.g.6.cded.78.e.9>:auth<Yet Another Society>
===> Found via inst#/home/rf/.local/bin/rakudo/share/perl6/site
zef:ver<0.14.5>:auth<github:ugexe>:api<0>

I have my raku installed at $HOME/.local/bin/rakudo Not sure if that would be causing this.

Just to rule out any suspicion on the module I'm trying to build it's just a simple module:

unit module Util;

sub read_file (Str $url) returns Seq is export {
    return $url.IO.lines;
}

Another thing I will mention is that I have never used zef before, and that I am very new to Raku. So if I'm missing something, please let me know!

Turns out, this was because I was cd'd into the wrong directory. This error is thrown if it can't find your META6.json

xylemase commented 1 year ago

I have the same problem described.

But, I cannot follow the comment "Turns out, this was because I was cd'd into the wrong directory. This error is thrown if it can't find your META6.json". What is the correct directory to be in? I tried searching my disc for instances of META6.json. Several exist, and they seem to be associated with previously installed raku modules. I tried changing to a subdirectory common to all these, but I still get the problem described when I run zef install Adverb::Eject and several other modules.

rawleyfowler commented 1 year ago

@xylemase You need to be in a directory that contains a META6.json to be able to run zef.

ugexe commented 1 year ago

The error message should be improved. For example when the install target is a path (starts with .) and also doesn't exist it shows:

$ raku -I. bin/zef install ./barz
The following were recognized as file paths but don't exist as such - ./barz

A similar error should be used when the install target exists as a path on the file system, and that path is a directory (and not an e.g. foo.tar.gz file), and that directory doesn't contain a META6.json file. As this issues shows, that is not the case currently:

$ mkdir barz
$ raku -I. bin/zef install ./barz
Type check failed for return value; expected IO::Path but got Any (Any)

Hello, I found out where my existing META6.json files are in my .zef folder. They all seem to be attached to prior zef downloads. I created a directory there called "my_naive_dir", copied one of the existing META6.json files into it, cd'd into it myself, upgraded zef, and then attempted to run a zef install from there.

I got the same result as in my last post here:

As far as I can tell, I complied with @rawleyfowler 's comment:

@xylemase You need to be in a directory that contains a META6.json to be able to run zef.

But even after this, zef install is not working.

ugexe commented 1 year ago

You need to run zef install . inside that directory, not zef install Adverb::Eject. Also you mention "copied one of the existing META6.json files into it" yet that isn't correct either, you need the entire project not just the META6.json file.

xylemase commented 1 year ago

I'm sorry, but I don't understand your instructions.I think there might be some misunderstanding between us about what I am trying to do. I want to install Adverb::Eject, or any of a number of other modules. I am accustomed to doing such a thing with CPAN or Conda, PIP, or even, in the somewhat distant past, with Zef. When I do this I can usually be anywhere on the disk and invoke something like Zef install Adverb::Eject. @ugexe, You say >"you need the entire project not just the META6.json file." So, what project would I copy?

I thought that the purpose of zef install ... was to install a project.

xylemase commented 1 year ago

Thank you for repeating your answer from before. However, that is not helping me.

I find this page, which says this is how you install CSV::Parser. zef install CSV::Parser. I think you authored this page. It doesn't say anything there about copying the project in the first place. I am under the impression that this IS the way you copy the project, but maybe you and I mean different things by the word "project". It seems that this may be where the misunderstanding is.

It would help if you opened a new issue and follow the instructions in issue template. Specifically it would have you run with --verbose or --debug to give more info, as well as list the output of zef list --installed which would show which outdated version of zef you are running (which is evident by the fact it is updating e.g. https://raw.githubusercontent.com/ugexe/Perl6-ecosystems/master/p6c1.json and not https://raw.githubusercontent.com/Raku/REA/main/META.json). I would suggest running zef nuke home site StoreDir (warning: this will uninstall all existing modules), and then reinstalling the latest version of zef via the instructions in the zef `README.md

xylemase commented 1 year ago

Thank you ! I will do what you suggest!

xylemase commented 1 year ago

I followed your suggestion, and zef is working for me now. Thank you!
