我正在努力学习和设置过去几天的Capistrano。到目前为止它是如何进行的：
$ cap production deploy

Tasks: TOP => deploy:updated => bundler:install
The deploy has failed with an error: #<SSHKit::Runner::ExecuteError: Exception while executing on host IP.IP.IP.IP: bundle exit status: 5
bundle stdout: Nothing written
bundle stderr: Nothing written
>
** Invoke deploy:failed (first_time)
** Execute deploy:failed
正如您所看到部署失败并出现捆绑退出状态：5。我不知道这意味着什么，但我使用以下命令修复了此问题：
$ sudo gem update --system
现在，当我运行$ cap production deploy时，我收到以下错误：
cap aborted!

The deploy has failed with an error: #<SSHKit::Runner::ExecuteError: Exception while executing on host IP.IP.IP.IP: bundle exit status: 16
bundle stdout: Nothing written
bundle stderr: Nothing written
所以现在它抱怨退出状态16，哈！
除此之外学习这一点非常令人沮丧，因为日志没有显示任何有意义的消息来寻找解决方法。或者，如果他们这样做，我不知道从哪里选择'退出状态：16'的含义并修复capistrano，以便简化（如果确实这样做！/ sarcasm）我的部署过程。
编辑：设置需要签入Gemfile.lock。问题已修复。另外我认为它可以帮助任何人在你的deploy.rb文件中设置：log_level，：debug而不是：info。

好的，这就是我解决它的方法：
Capistrano需要签入Gemfile.lock。从.gitignore文件中删除该行并将其提交到存储库中。
此外，如果它可以帮助任何人，那么在deploy.rb文件上设置：log_level，：debug（而不是：info）是有意义的。

将Rails从4.1.x升级到4.2后，我开始遇到类似的错误。我通过删除共享包目录来修复它。这是我采取的步骤：
cd /my/app/shared/bundle/ruby rm -rf 2.1.0或其他“版本”目录cap production deploy 此时，您可能会遇到内存问题（我在部署到DigitalOcean Droplet时执行了此操作）。解决方法是在Droplet上创建并启用交换文件。
