Zef::Client requires a cache parameter about zef

[ugexe]

I cannot reproduce, so my guess is zef is choosing a config that may not be what someone would expect. Specifically for this case its looking for a config file that is json, slurping it into a hash, and using the %hash<StoreDir> value for a default cache parameter

Zef::Config.find-config()
The order used is:

1. $cwd/config.json
2. $home/.zef/config.json
3. $cwd/.zef/config.json
4. %?RESOURCES<config.json>

As I cannot reproduce, could you run zef --help? The section under FLAGS, titled CONFIGURATION, will list the path of the file it will use for the config. Mine shows:
CONFIGURATION /home/nickl/.rakudobrew/moar-2016.04/install/share/perl6/site/resources/1F29702A476391AE0318E060ADE9CA2BB2B0F993.json

If this file does exist, could you verify it contains a "StoreDir" key and value?

If it does not exist or it shows nothing (I doubt this, as there should be a slurp related error occuring first), my guess would be %?RESOURCES<config.json> is possibly returning a bad path. I'd have to see what you are getting by adding the following to Zef::Config.find-config():

say "config.json".IO.perl;
say ($*HOME // $*CWD).child('.zef').child('config.json').perl;
say %?RESOURCES<config.json>.perl

Clearly better errors and debugging output are needed here 😦

Aha! I actually had an unrelated file named config.json (config for my own module) in the directory I was running zef in. False alarm. Sorry.
