我第一次尝试设置 debian 服务器（使用 puma、nginx、postgres sql 和 debian 10，来自托管商的 vps）
我使用 capistrano，我准备了一切，但是当我使 bundle exec cap production deploy 失败时，我的终端中有以下答案：
DEBUG [fe423141] /usr/local/rvm/rubies/ruby-3.0.0/lib/ruby/3.0.0/rubygems.rb:281:in `find_spec_for_exe'

我通过 ssh 访问我的服务器、我的应用程序文件和最后一个版本，我尝试安装 gem 捆绑器并进行捆绑更新。它似乎有效（但如果我在服务器的其他部分这样做，它就不起作用）。
root@my_app:~/my_app.com/releases/20210216183634# bundle update --bundlerThe git source `git://github.com/activeadmin/activeadmin.git` uses the `git` protocol, which transmits data without encryption.

Your Gemfile lists the gem hashie-forbidden_attributes (>= 0) more than once.
You should probably keep only one of them.
Remove any duplicate entries and specify the gem only once (per group).
While it's not a problem now, it could cause errors if you change the version of one of them later.

Bundle updated!
但是 bundle exec cap production deploy 仍然因为同样的原因失败
我的 deploy.rb 是这样的

部署的主要部分似乎已经成功，但最终bundler:config 失败了。
我迷路了，因为错误消息要求我做一些非常精确的事情，但它似乎不起作用。如果你有一个解决方案的想法，或者可以尝试的东西，甚至可以阅读它，这会对我有很大帮助。
非常感谢
