/ usr / bin / env ruby​​没有这样的文件或目录：使用capistrano 3，capistrano / rbenv，capistrano / bundler和capistrano

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：为什么在我的ssh会话中工作但在capistrano中没有工作 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-capistrano But 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: # # github/capistrano/rvm # github/capistrano/rbenv # github/capistrano/chruby # github/capistrano/bundler # github/capistrano/rails/tree/master/assets # github/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} #role :web, %w{deploy@example} #role :db, %w{deploy@example} # Extended Server Syntax # ====================== # This can be used to drop a more detailed server # definition into the server list.

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.
