Installation problem for edge: Zeitwerk::NameError: wrong constant name Refinerycms-authentication-devise inferred by Module from file

[timreganporter]

I'm doing a fresh install, using Rails 6.0.3.2 and Ruby 2.7.1.

Using: rails new rickrockstar -m https://www.refinerycms.com/t/edge

• Bundle install seems to work but then the installation croaks on db:create with:
  Zeitwerk::NameError: wrong constant name Refinerycms-authentication-devise inferred by Module from file
  The relevant line in the Gemfile is:
  gem 'refinerycms-authentication-devise', git: 'https://github.com/refinery/refinerycms-authentication-dev

• I tried changing the Gemfile entry to:
  gem 'refinerycms-authentication-devise', '~> 2.0.0'

and got this (which is similar to the error I get when installing from the 4.0 templates:

 In Gemfile:
    rails (~> 6.0.3, >= 6.0.3.2) was resolved to 6.0.3.2, which depends on
      actionmailer (= 6.0.3.2)

    refinerycms-authentication-devise (~> 2.0.0) was resolved to 2.0.0, which depends on
      actionmailer (< 5.2, >= 5.0.0)

I'm getting the same error with the same versions of Rails and Ruby.

Same issue when I try installing the edge version.

@jenxi n @timreganporter It had happened to me. As I needed a rails 6, I changed to confortable mexican sofa.
If you can handle rails 5, you may also try Lines gem from opoolo.

Same error (ruby 2.6.5, rails 6.0.3.4). I got around it by adding this to the new application's config/application.rb:

# Initialize configuration defaults for originally generated Rails version.
config.load_defaults 6.0
config.autoloader = :classic

Just like in this template file.

Then I navigated to the new app and run manually the commands inferred from www.refinerycms.com/t/edge:

rake db:create
rails generate refinery:cms --fresh-installation

That complained about a syntax error in Gemfile, but it was easy to fix, and then I run the generate command again.

Thanks for this @jussihirvi, I'm new to Refinery (literally just checking it out now) and i could not figure out why I was getting the Zeitwerk error. Your solution worked for me.
One question though, will the config.autoloader being set to classic create any other issues within the refinery setup?

Edit: I'm using Rails 6.0.3.4 and Ruby 2.7.1

[jussihirvi]

Bumper21, probably the setting will cause no problems because it is already used in a template file in the master branch.

However, a bug fix is on it's way, to allow the zeitwerk autoloader, as bricesanchez told here.
