ruby-on-rails - Capistrano 在清理期间无法删除节点模块

Question

我正在尝试部署 Rails 5.1 应用程序。我已经多次部署该应用程序没有问题，但现在，突然间我从 Capistrano 收到此错误消息

00:13 deploy:cleanup

SSHKit::Command::Failed: rm exit status: 1

Capistrano 用于删除旧版本的部署用户似乎没有足够的权限来删除 node_modules

我试图通过将 node_modules 设置为链接目录来解决此问题:

set :linked_dirs, %w{log tmp/pids tmp/cache tmp/sockets node_modules}

但这也没有解决它。

有人知道如何解决这个问题吗？

感谢您的帮助，

安东尼

ps:这是当前目录下 ls -lt 命令的输出:

Answer 1

根本原因

您以“sudo 方式”设置 NodeJS/npm，因此 npm 使用 root 安装包业主

Capistrano 删除了旧版本(如果我没记错的话，它默认只保留 10 个最新版本)以节省空间。由于您使用 deploy部署应用程序的用户，它没有删除文件的权限，所有者是 root

您之前没有看到此错误，因为您的版本数未达到保留的最大版本数(例如:10 个版本)

解决方案

既然你把你的node_modules要成为共享目录，您无需使用 sudo 修复 npm 问题。您可以简单地更改 releases 的所有者文件夹递归到 deploy:deploy .目的是使旧版本可以成功删除。该命令将是
sudo chown -R deploy:deploy /opt/www/absence-registrator/releases
