Capistrano gives "/usr/bin/env: ruby: No such file or directory" when performing cap deploy

Question

I am trying to deploy mailman with daemon and capistrano for my rails app into the production, but I receive this error on my local machine:

SSHKit::Runner::ExecuteError: Exception while executing on host 173.63.11.34: Exception while executing on host 178.62.16.69: script/mailman_daemon.rb exit status: 127
script/mailman_daemon.rb stdout: Nothing written
script/mailman_daemon.rb stderr: /usr/bin/env: ruby: No such file or directory

Below is my deploy.rb file:

end


# Mailman configuration

      within release_path do
        with default_env: fetch(:default_env) do

I am using capistrano (3.4.0) and capistrano-rvm (0.1.2).

And I have tried to use rvm1-capistrano3 and rvm-capistrano gem as suggested in this thread, but no luck.

Could somebody help out?

Thanks!

This is what I got what i do git grep usr.bin.env on my local machine:

bin/bundle:#!/usr/bin/env ruby.exe
bin/delayed_job:#!/usr/bin/env ruby
bin/rails:#!/usr/bin/env ruby.exe
bin/rake:#!/usr/bin/env ruby.exe

####################### UPDATE 2 #####################

I already have set the path for my rvm in my ~/.bash_profile:

export PATH="$PATH:$HOME/.rvm/bin" # Add RVM to PATH for scripting

[[ -s "$HOME/.profile" ]] && source "$HOME/.profile" # Load the default .profile

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*

Where do i type this? Anyway, I typed this out on the current directory of my production server, and i got this: `fatal: Not a git repository (or any of the parent directories): .git` — Ryzal Yusoff, Mar 09 '16 at 23:38
On your development machine. (Why didn't you try typing it on your development machine before asking?) — Andrew Grimm, Mar 10 '16 at 00:08
Oh sorry my bad..I have put the result on my original question above — Ryzal Yusoff, Mar 10 '16 at 00:15

Looks like the user deploy on 173.63.11.34 has no access to the ruby executable.

Make sure you install the ruby, rvm et, al, in the context of deploy user or in the global scope on 173.63.11.34.

One way to check is to ssh into 173.63.11.34 as deploy user and see if you will be able to execute ruby or rvm etc.

Hey thanks for the response, but I have definitely installed ruby and rvm in the context of `deploy` user. I have tried to ssh to the server and test ruby as u suggested and it works fine. I tested it with irb command like this: `deploy@Myapp:~/apps/myapp/current$ irb` – Ryzal Yusoff Mar 09 '16 at 23:43

either you have not installed your rvm or rbenv, chruby or ruby binary some other thing in your production server.

or more likely you misplaced or forgot to add the PATH and or source scripts like

for rvm

export PATH="$PATH:$HOME/.rvm/bin" # Add RVM to PATH for scripting

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"

or

for rbenv

export PATH="$PATH:$HOME/.rbenv/bin"

eval "$(rbenv init - )"

export PATH="$PATH:$HOME/.rbenv/plugins/ruby-build/bin"

or

for chruby

source /usr/share/chruby/chruby.sh

source /usr/share/chruby/auto.sh

RUBIES+=(/opt/rubies/*)

or

something like that

Hey, I have definitely have rvm installed on my production server, and I have also already set it's PATH on my ~/.bash_profile. See my Update 2 above – Ryzal Yusoff Mar 18 '16 at 16:41
Which shell do you get when you login as deploy in the remote shell. Is it sh bash ssh. Try command echo $SHELL if it is sh instead of bash, you .bash_profile won't work – krazedkrish Mar 19 '16 at 02:56
