Rails 7 assets install fails

[jcoyne]

It seems like it can't find the rails tasks for the gem it just installed:

Using rails 7.0.0.rc1
Using importmap-rails 0.9.3
Using stimulus-rails 0.7.3
Using turbo-rails 7.1.1
Bundle complete! 11 Gemfile dependencies, 53 gems now installed.
Use `bundle info [gemname]` to see where a bundled gem is installed.
         run  bundle binstubs bundler
       rails  importmap:install

Don't know how to build task 'importmap:install' (See the list of available tasks with `rails --tasks`)

(See full trace by running task with --trace)

The gem is added here: https://github.com/rails/rails/blob/main/railties/lib/rails/generators/app_base.rb#L317

and bundle install is called here: https://github.com/rails/rails/blob/main/railties/lib/rails/generators/app_base.rb#L414 And the generator is called here: https://github.com/rails/rails/blob/main/railties/lib/rails/generators/app_base.rb#L421

Possibly the problem is: "BUNDLE_GEMFILE"=>"/Users/jcoyne85/workspace/projectblacklight/blacklight/Gemfile"
