运行 rspec 时失败/错误，没有将字符串隐式转换为哈希

Question

我刚刚设置了一个新的 Rails 应用程序，该应用程序本身运行良好，但是在运行时 rspec 返回以下错误。我无法弄清楚这里出了什么问题。任何人都可以帮忙吗？所有测试都是从作曲家基础应用加载的，并且没有更改。

$ rspec

An error occurred while loading rails_helper.
Failure/Error: require File.expand_path('../../config/environment', __FILE__)

TypeError:
  no implicit conversion of String into Hash
# ./config/application.rb:10:in `<module:Smarthost>'
# ./config/application.rb:9:in `<top (required)>'
# ./config/environment.rb:2:in `require_relative'
# ./config/environment.rb:2:in `<top (required)>'
# ./spec/rails_helper.rb:4:in `<top (required)>'

Application.rb:（第 10 行如下：“class Application

require_relative 'boot'

require 'rails/all'

# Require the gems listed in Gemfile, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(*Rails.groups)

module Smarthost
  class Application < Rails::Application

    config.generators do |g|
      g.test_framework :rspec,
        fixtures: true,
        view_specs: false,
        helper_specs: false,
        routing_specs: false,
        controller_specs: false,
        request_specs: false
      g.fixture_replacement :factory_bot, dir: "spec/factories"
    end

    # Initialize configuration defaults for originally generated Rails version.
    config.load_defaults 5.2

    # Settings in config/environments/* take precedence over those specified here.
    # Application configuration can go into files in config/initializers
    # -- all .rb files in that directory are automatically loaded after loading
    # the framework and any gems in your application.
  end
end

使用 rake --trace 运行完整跟踪会返回以下指示 figaro 中的错误。不过，我还没有碰过这些文件中的任何一个。有什么想法可能是什么问题？

Answer 1

我最终通过重新安装 figaro 并在运行后将 application.yml 的旧内容复制到新创建的文件来解决此问题：

bundle exec figaro install
