尝试部署项目时出错

Question

我正在尝试将项目部署到VPS。 但是我遇到了这个错误：

如果我在VPS上运行bundle exec rake assets:precompile ，则会遇到相同的错误。

如果我运行bundle exec rake assets:precompile local， bundle exec rake assets:precompile收到以下消息：

alucardu@alucardu-VirtualBox ~/sites/wisemonkeys (frontend-update *) $ rake assets:precompile
rake aborted!

environment.rb

# Load the Rails application.
require File.expand_path('../application', __FILE__)

# Initialize the Rails application.
Wisemonkeys::Application.initialize!

这似乎很重要：

Psych :: BadAlias：未知别名：默认

Psych是YAML解析器。 您最近是否编辑了一个YAML文件，该文件可能具有这样的别名引用：

something:
  <<: *default

但是文件中没有default吗？ 也许您的database.ml或secrets.yml吗？
