cannot load such file -- json

[PabloMartinMoreno]

I can't run wpscan; I'm getting the following error:

/opt/wpscan/vendor/bundle/ruby/3.0.0/gems/activesupport-6.1.7.6/lib/active_support/core_ext/object/json.rb:4:inrequire': cannot load such file -- json (LoadError)

I'm using the latest version of wpscan and ruby-json 2.7.1-1, which seems to be causing the error. I'm using Arch Linux.

same issue in arch linux. Works on debian

Yeah Same for me in Arch, tried wpsan-git as well but same error again. Also tried installation of all gems mentioned in error but no luck.

I'm also attempting this on Arch for the first time. I tried running
gem install wpscan
and noticed an error about the following folder needing to be part of my PATH or gem executables will not run:
/home/grey0ut/.local/share/gem/ruby/3.0.0/bin
After appending that to my PATH variable I am now able to run wpscan without the above error.
Edit to add: from the Arch wiki on Ruby https://wiki.archlinux.org/title/Ruby#Configuration

I face the same issue on Arch. Works fine once installed with gem install

[uhtred-X]

Yeah with 'gem install wpscan' things are working good now.
