LoadError: cannot load such file -- config/deploy

Question

Ubuntu 20.04, Ruby 3.0.1, rails 6.1.3.1, Capistrano Version: 3.16.0 (Rake Version: 13.0.3)

Running any "cap" command results in the follow, for example :-

>> bundle exec cap install --trace
(in /)
cap aborted!
LoadError: cannot load such file -- config/deploy
Did you mean?  rbconfig/sizeof

I've tried creating new rails apps and the same error occurs.

Tried many different approaches (down grading ruby, rails etc) with same outcome. I think it may be a permissions issue and any help gratefully received.

UPDATE #2

Yep, running the command in the root of the application.

See code snippets below.

~/WebProjects/test_site$ ls -1
app
bin
config
config.ru
db
Gemfile
Gemfile.lock
lib
log
package.json
public
Rakefile
README.md
storage
test
tmp
vendor

~/WebProjects/test_site$ bundle exec cap install

(produces the error output in the question above)

Feels like something really simple but I just can't fathom it out (after many hours of head scratching!).

UPDATE #3

~/WebProjects/test_site$ cat /Capfile
load 'deploy' if respond_to?(:namespace) # cap2 differentiator
Dir['vendor/plugins/*/recipes/*.rb'].each { |plugin| load(plugin) }

load 'config/deploy' # remove this line to skip loading any of the default tasks

Answer 1

A Capfile was in the Ubuntu root directory (/) which was causing the problem.
