/ 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）
我正在使用capistrano，capistrano / rbenv，capistrano / bundler和capistrano / rails。 我在capistrano编译资产的步骤中收到此错误：
DEBUG [49a50df6] /usr/bin/env: DEBUG [49a50df6] ruby DEBUG [49a50df6] : No such file or directory DEBUG [49a50df6] 在生产服务器/usr/bin/env ruby -v是正确的。 我知道这一点： 为什么 – 做什么 – 在我的ssh-session中工作 – 但不是在capistrano但我无法让它工作。
这是我的Capfile ：

Dir.glob('lib/capistrano/tasks/*.cap').each { |r| import r }
这是我的deploy.rb ：

这是我的staging.rb ：

顺便说一下，我认为它与$PATH无关，因为bundle install运行得很好。
有谁知道发生了什么？
谢谢！
好吧，因为我有同样的问题，我花了很长时间来解决它：
您可能想知道为什么当您使用ssh使用shell登录时，此命令无法正常工作。
我不是专家（当我错了时，请纠正我）：问题是使用ssh登录远程服务器有几点不同。 引用capistrano的文档：
这真的是一个关于Capistrano使用哪种shell的问题，它是关于登录，非登录，交互或非交互的可能性的矩阵。
它们在这里有一个花哨的图形（在底部），它们说明了在登录过程中执行的文件的路径。 – 如果您想继续阅读本主题，给定的来源也很有趣。
出了什么问题？
当您使用ssh登录时，您（在登录时）执行多个文件（例如，当您使用bash时.bash_profile）。 通常，您的$ PATH变量会通过几个路径扩展到您的环境中的重要function。 但是不同的登录“样式”包括不同的文件。
正如文件中所述：
默认情况下，Capistrano始终指定一个非登录的非交互式shell。
在我的情况下，这导致我的登录文件.bash_profile不包括在内但它包括我的rvm的设置。 capistrano登录会话不知道我的rvm路径的结果。
我怎样才能解决这个问题？
对我来说，结果只是在Capfile （位于rails-project的根目录中）中需要’capistrano / rvm’ （我正在使用RVM）行中取消注释 。
希望能帮助别人。
编辑：
并确保在Gemfile中包含gem’capistrano gem 'capistrano-rvm' ！
好的，修好了。
我补充说：
set :default_env, { path: "~/.rbenv/shims:~/.rbenv/bin:$PATH" }
到我的deploy.rb 。
我不确定是最好的解决方案，但它确实有效。
我想你应该执行
apt-get install git-core
在你的服务器上
我使用rbenv时遇到了同样的问题。 为我解决的是在捆绑器之前包括rbenv库 – 而不是之后。 订单结果非常重要。 这是我的Capfile中的内容：
require 'capistrano/rbenv' require 'capistrano/bundler'
如果你做得对，你应该看到使用rbenv前缀执行bundle命令，沿着这些方向：
XX RBENV_ROOT=$HOME/.rbenv RBENV_VERSION=2.3.0 $HOME/.rbenv/bin/rbenv exec bundle install ...
错误的解决方案：
/ usr / bin / env git没有这样的文件或目录capistrano
在远程服务器中安装git，即要进行部署的机器。
apt-get install git
确保在Capfile中要求所有这些gem。
当我在终端上以交互方式键入bundle install ，它工作正常。 现在，当我通过Capistrano使用它时，它不起作用。
我这样解决了：
在Ubuntu中， ~/.bashrc中有一段代码表示：
# If not running interactively, don't do anything case $- in *i*) ;; *) return;; esac
当你运行Capistrano时，它实际上会使用你的~/.bashrc 但它不会在该代码块下面运行任何命令。
因此，我修复了将bundle install所需的代码行移到该代码块之上的问题，因此Capistrano可以加载它们。
你可以通过运行which bundle来获得一些移动线的提示。
