我正在使用 capistrano、capistrano/rbenv、capistrano/bundler 和 capistrano/rails。我在 capistrano 编译 Assets 的步骤中得到这个错误:

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。我知道这一点:why-does-something-work-in-my-ssh-session-but-not-in-capistrano但我无法让它工作。

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{deploy@example.com}
#role :web, %w{deploy@example.com}
#role :db, %w{deploy@example.com}

# 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'

这是完整的轨迹:

顺便说一下,我认为它与 $PATH 无关,因为 bundle install 运行得很好。

有人知道这是怎么回事吗?

谢谢!

最佳答案

好的,因为我遇到了同样的问题,我花了很长时间才解决它:

您可能想知道为什么当您使用 ssh 登录到您的 shell 时,这个命令正在工作,但它却不工作。

我不是专家(所以当我错了时请纠正我):问题是使用 ssh 登录远程服务器有几个不同之处。引用 capistrano 的文档:

It's really a question of which kind of shell Capistrano is using, it's a matrix of possibilities concerning login, non-login, interactive, or non-interactive.

他们有精美的图形 here (在底部)它们说明了在登录过程中执行的文件的路径。 - 如果您想继续阅读该主题,给定的来源也很有趣。

出了什么问题?

当您使用 ssh 登录时,您(在登录时)正在执行多个文件(例如,当您使用 bash 时是 .bash_profile)。通常,您的 $PATH 变量会扩展到您环境中重要功能的多个路径。但是不同的登录“样式”包括不同的文件。

正如文档再次所说:

By default Capistrano always assigns a non-login, non-interactive shell.

在我的例子中,这导致我的登录文件 .bash_profile 不包含在内,但它包含了我的 rvm 的设置。结果是 capistrano 登录 session 不知道我的 rvm 路径。

我该如何解决这个问题?

对我来说,结果只是Capfile<中require 'capistrano/rvm'(因为我使用的是RVM)行的取消注释/strong>(位于您的 rails 项目的根目录中。

希望能帮助到别人。

编辑:

并且确保在 Gemfile 中包含 gem 'capistrano-rvm'!
