'No Rakefile found' error from the 'cap install' command

Question

I'm trying to convert an old project from cap2 to cap3. After deleting the old Capfile, running cap install gives me:

$ cap install
(Backtrace restricted to imported tasks)
cap aborted!
No Rakefile found (looking for: capfile, Capfile, capfile.rb, Capfile.rb, /usr/lib/ruby/vendor_ruby/Capfile)
/usr/bin/cap:3:in `<main>'
(See full trace by running task with --trace)

isn't the install command meant to create the Capfile?

I get the same error if I run the cap install command on a new project (= empty folder).

I'm using version 3.4.0.

Answer 1

$ rbenv rehash

Since I am using rbenv, the above command worked for me!

Answer 2

I setup a test environment and re-produced the error:

$ cap install
(Backtrace restricted to imported tasks)
cap aborted!
No Rakefile found (looking for: capfile, Capfile, capfile.rb,  Capfile.rb, /usr/lib/ruby/vendor_ruby/Capfile)
/usr/bin/cap:3:in `<main>'
(See full trace by running task with --trace)

$ cap --trace install
cap aborted!
No Rakefile found (looking for: capfile, Capfile, capfile.rb,  Capfile.rb, /usr/lib/ruby/vendor_ruby/Capfile)
/usr/lib/ruby/vendor_ruby/rake/application.rb:684:in `raw_load_rakefile'
/usr/lib/ruby/vendor_ruby/rake/application.rb:94:in `block in load_rakefile'
/usr/lib/ruby/vendor_ruby/rake/application.rb:176:in `standard_exception_handling'
/usr/lib/ruby/vendor_ruby/rake/application.rb:93:in `load_rakefile'
/usr/lib/ruby/vendor_ruby/rake/application.rb:77:in `block in run'
/usr/lib/ruby/vendor_ruby/rake/application.rb:176:in `standard_exception_handling'

/usr/lib/ruby/vendor_ruby/capistrano/application.rb:15:in `run'
/usr/bin/cap:3:in `<main>'

Located Capfile and ran the command

$ cap --rakefile /usr/lib/ruby/vendor_ruby/capistrano/templates/Capfile install
mkdir -p config/deploy
create config/deploy.rb
create config/deploy/staging.rb
create config/deploy/production.rb
mkdir -p lib/capistrano/tasks
create Capfile
Capified

It works.

If you have installed Ruby & Capistrano for debian package then the Capfile can be now found in directory /usr/lib/ruby/vendor_ruby/capistrano/templates/Capfile. So use the command cap --rakefile /usr/lib/ruby/vendor_ruby/capistrano/templates/Capfile install indicating the right path to Capfile.

Answer 4

I had the same problem, my capistrano used to work fine, but something happened. I believe i updated my ruby in some moment and the capistrano stopped to work. So when i ran cap install the result was:

So i discovered that the Capfile changed directory, from /usr/lib/ruby/vendor_ruby/Capfile to /usr/lib/ruby/vendor_ruby/capistrano/templates/Capfile. So to work i used the command cap --rakefile /usr/lib/ruby/vendor_ruby/capistrano/templates/Capfile install and it worked for me.
