Capistrano部署抛出心理错误:错误的参数数(给定4，预期1) :`safe_load‘’

Question

在我当地的机器上，这个项目运行得很好。Bundle安装工作正常，我可以在本地运行该项目。到目前为止，我所有的部署都很顺利。但是，启动此部署(对任何gems或代码都不做任何更改)，即使不以任何方式更改现有代码，部署也会以以下错误的->开始破坏捆绑安装。

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:我寻找正在添加精神病学Gem的Gem ( Gemfile中没有直接列出它)。然后，我将父Gem的版本限制为不下载精神病学的以前版本。然后，我在部署代码的服务器上运行gem uninstall psych。从服务器上删除了所有版本的精神病学。然后部署进行得很好。
