Capistrano 3:运行自定义 shell 命令时无法识别捆绑程序 [英] Capistrano 3: bundler not recognized when running custom shell command
问题描述
我在 RVM 上使用 jruby 部署 Capistrano 时遇到问题.我使用 PUMA 作为应用服务器，这需要我在 Gemfile 中添加 capistrano3-puma.总而言之，一切似乎都运行良好，我的服务器代码从 git 存储库中保持最新状态，并且以前版本的代码很好地存档.除了，每次我尝试从 Capistrano 任务运行 shell 命令时，例如，bundle exec pumactl -F config/puma.rb start"，例如 Capistrano 似乎无法识别 bundle 命令.
I'm having an issue implementing Capistrano deployment with jruby on RVM. I'm using PUMA as app server and that requires me to add capistrano3-puma in my Gemfile. All in all, everything seems to work perfectly, my server's code got up-to-date fine from the git repo, and had the previous version of code archived nicely. Except, every time I try to run shell command from Capistrano task, such as, "bundle exec pumactl -F config/puma.rb start", for example, Capistrano can't seem to recognise bundle command.
我的真实案例如下所示，当我在覆盖的 deploy:start 方法中运行上述命令时，它返回错误bundle: command not found".当我通过 SSH 登录到服务器并直接从应用程序文件夹启动它时，我已经测试了相同的命令工作正常.
My real case example is shown as below, when I run the above mentioned command in an overrided deploy:start method it return an error "bundle: command not found". I already tested the same command works fine, when I log on to the server via SSH and launch it from the app folder directly.

任何帮助我解决问题的建议将非常非常感谢.
any advice to help me resolve the problem would be very, very much appreciated.
按照垃圾建议编辑代码后，现在我发出这样的命令 => 执行cd #{current_path} &&/bin/bash -l bundle exec pumactl -F config/puma.rb start"现在，它到达并抱怨全局 rvm 路径下的 bundler.确切的新错误如下所示.
after editing the code as rubish suggested, now instead I issue the command like this => execute "cd #{current_path} && /bin/bash -l bundle exec pumactl -F config/puma.rb start" now, it get to and is complaining about bundler under global rvm path. The exact new error looks like the following.

推荐答案
通常 RVM 仅在登录 shell 中初始化，因此 capistrano 命令不知道 RVM.只需更改您的 shell 命令即可解决此问题:
Generally RVM is initialized only in a login shell, so capistrano commands are unaware of RVM. Simply change your shell command to fix this:
# play nice with rvm
set :default_shell, '/bin/bash -l'
