我正在尝试使用Capistrano 3.0将我的rails应用程序部署到EC2示例中。现在，我将堆栈以下输出，这些输出在运行“cap production deploy”或“cap production bundler：install”时出现。

Tasks: TOP => bundler:install

当ssh-ing进入服务器并运行相同的命令（cd /var/www/app/current && /usr/bin/env bundle --gemfile /var/www/app/current/Gemfile --path /var/www/app/shared/bundle --deployment --verbose --binstubs /var/www/app/shared/bin --without development test）时，一切似乎都正常。

指示未找到或未安装bundler。Capistrano（如本文http://www.capistranorb.com/documentation/faq/why-does-something-work-in-my-ssh-session-but-not-in-capistrano/所述）在非登录、非交互式shell中运行。
我猜bundler安装在一个特殊的路径中，或者您使用的是rvm、chruby或rbenv，并且这些东西没有像您SSH到机器中时那样初始化，因为Capistrano使用的是非登录、非交互式会话。
解决方案是使用capistrano-{rvm,chruby,rbenv} gem，它适合您的环境，如Capfile中所述。
如果您没有使用这些版本管理器之一，请尝试以下操作：

ssh me@theserver 'which bundler'

也许你会看到没有输出（更多关于为什么在上面的链接），解决这个问题，卡皮斯特拉诺将工作。

问题确实出在 * 非交互式shell* 上。
最后，我不得不在.bashrc中添加以下行：

source ~/.rvm/scripts/rvm

如果其他人遇到类似的问题，我将补充说，我还必须Maprake命令，以便它可以正常工作。必须添加以下行到我的deploy.rb文件：

SSHKit.config.command_map[:rake] = "bundle exec rake"

你最好使用capistrano-rbenv gem来管理你的ror环境
1.添加gem 'capistrano-rbenv', '~> 2.0' to your宝石文件
1.取消注解capfile中的require 'capistrano/rbenv';如果capistrano/bundler已注解，则也取消注解
1.在部署文件中设置rbenv_ruby变量set :rbenv_ruby, '2.0.0-p247'
那就都准备好了！

我可以通过在~/.bashrc中添加以下代码来解决这个问题：

export RBENV_ROOT="${HOME}/.rbenv"

if [ -d "${RBENV_ROOT}" ]; then
  export PATH="${RBENV_ROOT}/bin:${PATH}"
  eval "$(rbenv init -)"
fi

我回答这个问题有点晚了，但它可能会帮助一些像我这样的用户。
如果您使用的是rbenv，则通过在deploy.rb中的下面一行中添加以下内容来设置rbenv的默认环境
set :default_env, { path: "~/.rbenv/shims:~/.rbenv/bin:$PATH" }

系统中缺少bundle可执行文件，或者shell不知道其路径。
检查以下测试：
系统可以找到perl可执行文件：

# /usr/bin/env perl
^C   << I did CTRL+C as perl was expecitng me to put some code

现在，我的系统找不到perlyo可执行文件，并抛出错误：

# /usr/bin/env perlyo
/usr/bin/env: perlyo: No such file or directory

以上错误与/usr/bin/env bundle的错误类似，即：

DEBUG [f15c9f08]    /usr/bin/env: 
DEBUG [f15c9f08]    bundle
DEBUG [f15c9f08]    : No such file or directory

通过运行以下命令检查系统是否知道bundle：

# which bundle
# whereis bundle

如果使用上述命令无法找到，则检查系统上是否存在bundle，如下所示：

# updatedb
# locate bundle

如果找到bundle，则相应地添加它的path，以便shell能够识别它。
希望这个有用。

正如@zpieslak所说：
在~/.bashrc中添加以下内容：

if [ -d "${RBENV_ROOT}" ]; then
  export PATH="${RBENV_ROOT}/bin:${PATH}"
  eval "$(rbenv init -)"
fi

此行之前：

# If not running interactively, don't do anything
case $- in
    *i*) ;;
      *) return;;
esac
