title: Supervisord with rails - can't find command 'RAILS_ENV=production'
body: <p>I try to run sidekiq service with supervisord</p>
  
  <p>Here's my config:</p>
  
  <pre><code>[program:my-app-sidekiq-staging]
  directory=/srv/www/DOMAIN/current
  command=RAILS_ENV=production /usr/local/rvm/bin/rvm ruby-2.2.2@my-app-staging do bundle exec sidekiq -e production -d -C config/sidekiq.yml -L log/sidekiq.log
  autostart=true
  autorestart=true
  redirect_stderr=true
  </code></pre>
  
  <p>After startup I’m have fatal error: </p>
  
  <pre><code>can't find command 'RAILS_ENV=production'
  </code></pre>
  
  <p>I’m confused, because my config for rails runs without errors</p>
  
  <pre><code>directory=/srv/www/DOMAIN/current
  command=RAILS_ENV=production /usr/local/rvm/bin/rvm ruby-2.2.2@my-app-staging do bundle exec passenger start -S tmp/unicorn/ilp-app-unicorn.sock --environment production --friendly-error-pages
  </code></pre>
