Capistrano 部署引发心理错误：arguments 的编号错误（给定 4，预期为 1）：`safe_load'

Question

在我的本地机器上，该项目运行良好。 捆绑安装工作正常，我可以在本地运行项目。 到目前为止，我所有的部署也都运行良好。 但是开始这个部署（没有更改任何 gem 甚至代码），即使没有以任何方式更改现有代码，部署开始在捆绑安装时中断，并出现以下错误 ->

Rails -> '5.0.7.2'
Ruby -> 2.5.3
Bundler             1.16.6
Deployment Tool -> Capistrano '3.11.0'

Answer 1

解决方案：我寻找添加 Psych Gem 的 Gem（它没有直接列在 Gemfile 中）。 然后我将该父 Gem 的版本限制为不下载 Psych 的先前版本。 然后我在部署代码的服务器上运行gem uninstall psych 。 从该服务器中删除了所有版本的 Psych。 然后部署工作正常。
