deployment - 以 username@servername : no implicit conversion of Array into String 身份执行时出现 Capistrano 异常

Question

我正在尝试将我的应用程序推送到我的服务器，我正在运行 Rails 5.2、Ruby 2.4.6 和 Capistrano 3。我过去的应用程序在服务器端 Rails 4.2 上运行。

当我尝试运行时 cap production deploy:check --trace并获得:

** Invoke deploy:check:make_linked_dirs (first_time)
** Execute deploy:check:make_linked_dirs
cap aborted!
SSHKit::Runner::ExecuteError: Exception while executing as username@servername: no implicit conversion of Array into String

生产.rb

server "servername", user: "deploy", roles: %w{app db web}

我环顾四周，但没有看到任何关于为什么我没有将 Array 隐式转换为 String 的信息。我把东西塞进了linked_dirs吗？如果我需要添加任何其他代码，请告诉我。我不知道从哪里看这一点。

Answer 1

如果您打印变量 cap -p production deploy:check我们你会看到变量 :linked_files => [["config/master.key"]]是数组列表而不是字符串列表。

你可以改变你的线路

append :linked_files, "config/master.key"
