Is is due because rexml should be a runtime dependency and not a dev one?

WinRM/lib/winrm/http/response_handler.rb

Line 15 in ebbed11

require 'rexml/document' unless defined?(REXML::Document)

or because an incompatibility was brought by the last version of rexml because the version is not locked in the gemspec?

It seems doing gem install rexml fixes the problem. The reason is that before, rexml was a "default gem" and from ruby 3 or higher is a "bundled gem". Is explained here: https://stackoverflow.com/questions/65479863/rails-6-1-ruby-3-0-0-tests-error-as-they-cannot-load-rexml

Probably we should add it to evil-winrm Gemfile and Gemfile.lock.

We did a commit to fix this on future version: Hackplayers/evil-winrm@83bc6ec

Yes but since it's loaded at runtime it should be added as add_runtime_dependency rather than add_development_dependency in the gemspec.

Please, enable private messages on twitter or contact me on IRC or Discord (OscarAkaElvis#3764) to keep talking about this further.

[noraj]

I'll try to PM you on discord else https://docs.github.com/en/discussions

To add it as a runtime dependency is something that WinRM staff should do. From our side (evil-winrm team) already did a commit to fix it. Let's see what WinRM staff do.

Also just ran into this. I think winrm should add rexml as a dependency since it's using it, Users and package managers will increasingly switch to Ruby 3.x and adding rexml as a dependency means you will get newer versions of the library.

actually for me gem install winrm and gem install winrm-fs solved the issue

[mwrock]

oh yes fixed in #334
