Question posted in 
I am on windows machine while using the command line i get this error
“(Backtrace restricted to imported tasks) cap aborted! LoadError: cannot load such file — capistrano/passenger C:/Sites/Buy/Capfile:23:in `’
(See full trace by running task with –trace)”
And on git bash with the same command i have this error.
” cap production deploy C:/tools/ruby21/lib/ruby/2.1.0/rubygems.rb:235:in bin_path': can't find gem capistrano ([">= 0.a"]) (Gem::GemNotFoundException)‘”

You may have included a line in
Capfilethat is:Please remove this line and try again
cap production deploy:initialThe new capistrano requires the passenger file but I think you are not using passenger but webrick, puma or unicorn. So that is the reason your cap cannot find passenger.

I had same error but with:
I commit the line (in your case 23) in Gapfile and the deploy work with no problems.
