我真的想部署一个应用程序，并一直关注Michael Hartl的railstutorial。现在，我即将在Digital Ocean部署我的第一个应用程序，但我继续遇到很多问题。无论如何，大部分已经完成，除了这个大的。
我跟随Hoang Pham的这个blog和[Andrew Gertig]的教程[3]。
无论如何，这是我第一次进入这里。我先提前表示感谢。每次我做$ cap deploy:cold，在我的本地机器上，我总是会收到这个错误。
失败：“rvm_path = $ HOME / .rvm $ HOME / .rvm / bin / rvm-shell'default'-c 'cd / home / deployer / apps / tiangge / releases / 20150123165947＆amp;＆amp;束 安装--gemfile / home / deployer / apps / tiangge / releases / 20150123165947 / Gemfile --path / home / deployer / apps / tiangge / shared / bundle --demployment --quiet - 没有开发测试'“在128.199.74.8
我也注意到这一点，这就是我在VPS中再次gem uninstall bundler和gem install bundler的原因

您遇到Cannot allocate memory错误。这意味着您的部署机器上没有足够的RAM用于捆绑器。
您可以添加交换分区来执行此操作，或创建具有更大RAM空间的DO小滴。

我在尝试在Digital Ocean / Ubuntu上部署Dokku时遇到了类似的问题。 在根数字海洋用户的SSH会话中运行3行代码轻松修复：
dd if=/dev/zero of=/swapfile bs=1024 count=1024000
mkswap /swapfile
swapon /swapfile
