Question

我最近升级了许多宝石，从那时起，我无法运行Rails服务器，控制台或rspec。

这是我看到的错误日志：

升级的一部分包括将Rails升级到5.2.3，这迫使我从new_framework_defaults.rb文件中删除了这一行：

# Do not halt callback chains when a callback returns false. Previous versions had true.
ActiveSupport.halt_callback_chains_on_return_false = false

我猜想这与它有关吗？

编辑：下面是工厂代码。在升级gems之前，此确切的代码可以100％工作：

FactoryBot.define do
  factory :book do
    name "my songbook"
  end
end

Answer 1

FactoryBot更改了其语法。现在，在将值（甚至是静态值）分配给变量时，需要一个块。将您的代码更改为此：

FactoryBot.define do
  factory :book do
    name { "my songbook" }
  end
end

请参阅其文档中的Defining Factories。

Factorybot无法识别任何属性-“缺少方法”错误
