无法使用 Capistrano 删除旧版本

Question

我最近将我的 Rails 应用程序从 Ruby 2.7.3 升级到 3.0.1。现在我无法在使用 Capistrano 部署时删除旧版本。我收到以下错误

 DEBUG [f5dff474]       rm: cannot remove '/home/deploy/apps/myapp/releases/20210527195617/tmp/cache/bootsnap/compile-cache/36/9709c0fbdbcd6c': Permission denied

我在 shared/tmp/cache/

上尝试了 chmod -R 777 和 chown $USER

我也试过了this solution，我得到了错误

OptionParser::AmbiguousOption: ambiguous option: -s


Caused by:
OptionParser::InvalidOption: invalid option: s


Caused by:
ArgumentError: wrong number of arguments (given 1, expected 0)

我也试过设置 set :use_sudo, true

Answer 1

感觉您的 capistrano 可能与参考答案中的不一样。您也许可以跳过 -s 参数并尝试：

cap production deploy:cleanup use_sudo=true

请注意，由于 3.x，某些参数（例如 use_sudo）不再是必需的。

您也可以尝试在清理上限前加上 sudo，看看会发生什么：

sudo cap production deploy:cleanup

很可能两者都不起作用，然后我建议查看此文档：upgrading capistrano from 2.xx 更具体地说，第 2 项建议从头开始对项目进行 capify 项目并手动移动旧的 cap 文件。

编辑：您可以使用 sudo 并手动删除有问题的目录吗？

sudo rm -rf /apps/myapp/releases/20210527195617/tmp/cache/bootsnap/compile-cache/36/9709c0fbdbcd6c

如果可行 - 这意味着您需要调整权限，以便允许您的 capistrano 用户删除该文件夹。如果不能这样做，手动清理以前的版本，然后从那里开始用新用户完成的新部署应该可以工作。

Answer 2

运行 sudo chown deploy app/myapp/releases 解决了这个问题。仍然时不时弹出，但这已修复它。

Answer 3

您已经找到适合您的解决方案，但无需先设置正确的所有者/权限即可强制删除的其他方法是将“rm”重新映射到“sudo rm”：

SSHKit.config.command_map[:rm] = 'sudo rm'

所以 capistrano 中的每个“rm”调用都将使用“sudo rm”。当然，您的 capistrano 用户需要无密码的 sudo。
