本文介绍了/ usr / bin / env ruby没有这样的文件或目录：使用capistrano 3，capistrano / rbenv，capistrano / bundler和capistrano / rails（使用rails 4）的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在使用capistrano，capistrano / rbenv，capistrano / bundler和capistrano / rails。在capistrano编译资产的步骤中，我得到此错误：
I'm using capistrano, capistrano/rbenv, capistrano/bundler and capistrano/rails. I get this error in the step where capistrano compiles the assets:
DEBUG [49a50df6] /usr/bin/env:
DEBUG [49a50df6] ruby
DEBUG [49a50df6] : No such file or directory
DEBUG [49a50df6]
在生产服务器中， / usr / bin / env ruby -v 是正确的。
我知道：
但是我无法理解
In the production server /usr/bin/env ruby -v is correct.I'm aware of this: why-does-something-work-in-my-ssh-session-but-not-in-capistranoBut I can't get it to work.
这是我的 Capfile ：
# Load DSL and Setup Up Stages
require 'capistrano/setup'
# Includes default deployment tasks
require 'capistrano/deploy'
# Includes tasks from other gems included in your Gemfile
#
# For documentation on these, see for example:
#
# https://github.com/capistrano/rvm
# https://github.com/capistrano/rbenv
# https://github.com/capistrano/chruby
# https://github.com/capistrano/bundler
# https://github.com/capistrano/rails/tree/master/assets
# https://github.com/capistrano/rails/tree/master/migrations
#
# require 'capistrano/rvm'
require 'capistrano/rbenv'
# require 'capistrano/chruby'
require 'capistrano/bundler'
require 'capistrano/rails/assets'
require 'capistrano/rails/migrations'
# Loads custom tasks from `lib/capistrano/tasks' if you have any defined.
Dir.glob('lib/capistrano/tasks/*.cap').each { |r| import r }
这是我的 deploy.rb ：
# rbenv
set :rbenv_type, :user
set :rbenv_ruby, '2.0.0-p247'
# bundler
set :bundle_gemfile, -> { release_path.join('Gemfile') }
set :bundle_dir, -> { shared_path.join('bundle') }
set :bundle_flags, '--deployment --quiet'
set :bundle_without, %w{development test}.join(' ')
set :bundle_binstubs, -> { shared_path.join('bin') }
set :bundle_roles, :all
# rails
set :rails_env, 'production'
set :application, 'MY APP'
set :repo_url, 'MY_REPO.git'
# ask :branch, proc { `git rev-parse --abbrev-ref HEAD`.chomp }
# set :deploy_to, '/var/www/my_app'
# set :scm, :git
# set :format, :pretty
# set :log_level, :debug
# set :pty, true
set :linked_files, %w{.env config/database.yml}
# set :linked_dirs, %w{bin log tmp/pids tmp/cache tmp/sockets vendor/bundle public/system}
# set :default_env, { path: "/opt/ruby/bin:$PATH" }
set :keep_releases, 5
namespace :deploy do
desc 'Restart application'
task :restart do
on roles(:app), in: :sequence, wait: 5 do
# Your restart mechanism here, for example:
# execute :touch, release_path.join('tmp/restart.txt')
end
end
after :restart, :clear_cache do
on roles(:web), in: :groups, limit: 3, wait: 10 do
# Here we can do anything such as:
# within release_path do
# execute :rake, 'cache:clear'
# end
end
end
after :finishing, 'deploy:cleanup'
end
这是我的 staging.rb ：
set :stage, :staging
# Simple Role Syntax
# ==================
# Supports bulk-adding hosts to roles, the primary
# server in each group is considered to be the first
# unless any hosts have the primary property set.
#role :app, %w{[email protected]}
#role :web, %w{[email protected]}
#role :db, %w{[email protected]}
# Extended Server Syntax
# ======================
# This can be used to drop a more detailed server
# definition into the server list. The second argument
# something that quacks like a has can be used to set
# extended properties on the server.
#server 'example.com', user: 'deploy', roles: %w{web app}, my_property: :my_value
server 'my_server', user: 'my_user', roles: %w{web app db}
# you can set custom ssh options
# it's possible to pass any option but you need to keep in mind that net/ssh understand limited list of options
# you can see them in [net/ssh documentation](http://net-ssh.github.io/net-ssh/classes/Net/SSH.html#method-c-start)
# set it globally
# set :ssh_options, {
# keys: %w(/home/rlisowski/.ssh/id_rsa),
# forward_agent: false,
# auth_methods: %w(password)
# }
# and/or per server
# server 'example.com',
# user: 'user_name',
# roles: %w{web app},
# ssh_options: {
# user: 'user_name', # overrides user setting above
# keys: %w(/home/user_name/.ssh/id_rsa),
# forward_agent: false,
# auth_methods: %w(publickey password)
# # password: 'please use keys'
# }
# setting per server overrides global ssh_options
# fetch(:default_env).merge!(rails_env: :staging)
set :deploy_to, '/home/my_user'
这是完整的踪迹：

Tasks: TOP => deploy:assets:precompile
顺便说一句，我认为这与不相关$ PATH ，因为捆绑安装运行得很好。
By the way, I think it's not related to $PATH, because bundle install runs just fine.
有人知道会发生什么吗？
Does anyone know what's going on?
谢谢！
推荐答案
确定。
我添加了此内容：
set :default_env, { path: "~/.rbenv/shims:~/.rbenv/bin:$PATH" }
deploy.rb 。
我不确定这是最好的解决方案，但它确实有效。
I'm not sure is the best solution, but it worked.
