Ruby on rails 为什么'；rake资产：预编译&x27；给予'；NoMethodError:nil:NilClass'；的未定义方法[]；？

我正试图用Capistrano部署一个项目，但我遇到了这个错误

当我直接在服务器上运行命令时，同样的情况也会发生。下面是

/opt/rbenv/shimmes/bundle exec rake资产的输出：预编译--trace

**调用资产：预编译（第一次）
**调用资产：环境（第一次）
**执行资产：环境
**调用环境（第一次）
**执行环境
**执行资产：预编译
雷克流产了！
NoMethodError:nil类的未定义方法“[]”
