尝试加载 gem '设计时出错。 ActiveSupport：无法将持续时间强制转换为整数

Question

我已经尝试修复这个错误一段时间了，但没有找到任何帮助，请帮忙。

我正在尝试运行使用设计 gem 在我的 ROR 应用程序上进行迁移。但是我从 ActiveSupport 收到错误消息“无法将持续时间强制转换为整数”。这发生了然后我尝试运行:

rake db:migrate

我不确定它是否与迁移代码有关，或者是否与新设计版本有关。这是错误消息：

我正在使用：

gem 'rails', '4.1.1'
gem 'devise', '~> 4.2.0'

请告诉我怎样才能使这个问题变得更好。问候。

编辑：这是迁移文件之一：

class DeviseCreateUsers < ActiveRecord::Migration
def change
create_table(:users) do |t|
  t.string :email,              null: false, default: ""
  t.string :encrypted_password, null: false, default: ""
  t.string   :reset_password_token
  t.datetime :reset_password_sent_at
  t.datetime :remember_created_at
  t.integer  :sign_in_count, default: 0, null: false
  t.datetime :current_sign_in_at
  t.datetime :last_sign_in_at
  t.string   :current_sign_in_ip

end
end
end

Answer 1

尝试运行 bundle exec rake db:migrate 并让我知道输出结果。如果前面没有 bundle exec，它将不知道要使用哪些 gem 并且将使用本机（系统）gem。

也尝试运行 bundle update 然后 re-running 迁移。

Answer 2

今天在尝试将旧应用升级到 rails 4 时遇到问题。

问题是 ruby 版本 (2.4.0) 而不是自己设计的。考虑使用 ruby-2.3.3 或更低版本，它会非常有效！

Answer 3

我昨天在 rails 3.2 和 ruby 2.4 一起工作时遇到了这个问题。我通过猴子修补问题所在的 activesupport 库来修复它。

解决方法：调换乘法顺序，把Duration放在第一位

在您的 rails 初始值设定项中包含以下代码：

# pulled from https://github.com/rails/rails/blob/v3.2.22.5/activesupport/lib/active_support/core_ext/numeric/time.rb

class Numeric
  def days
    ActiveSupport::Duration.new(24.hours * self, [[:days, self]])
  end
  alias :day :days

  def weeks
    ActiveSupport::Duration.new(7.days * self, [[:days, self * 7]])
  end
  alias :week :weeks

  def fortnights
    ActiveSupport::Duration.new(2.weeks * self, [[:days, self * 14]])
  end
  alias :fortnight :fortnights
end

# pulled from https://github.com/rails/rails/blob/v3.2.22.5/activesupport/lib/active_support/core_ext/integer/time.rb

class Integer
  def months
    ActiveSupport::Duration.new(30.days * self, [[:months, self]])
  end
  alias :month :months

  def years
    ActiveSupport::Duration.new(365.25.days * self, [[:years, self]])
  end
  alias :year :years
end

Answer 4

切换到 rails 版本至少 5.0.2，删除你的 Gemfile.lock 和运行 bundle update.

5.2.0 是最新的，发布于 2018 年 4 月 9 日..

Answer 5

今天，我遇到了同样的问题，但版本不同，我的 ruby 版本 2.4.2 和 rails 版本 4.0.13.

我遇到了同样的错误，现在已修复。感谢@thomas-dziedzic。

解决方法是：

我从 https://github.com/rails/rails/commit/32f215c3014e580e512db5e8772d0deadf3d6497
我按照这个编辑link然后编辑https://github.com/rails/rails/blob/32f215c3014e580e512db5e8772d0deadf3d6497/activesupport/lib/active_support/core_ext/numeric/conversions.rb

当我编辑 active_support 时，问题解决了。

Answer 6

实际上我在尝试安装时遇到了同样的问题运行 activeadmin 在这些条件下：

rails 3.2.22.5 ruby2.3.8

对我没有完全起作用，因为在应用程序启动之前调用了 ActiveSupport。

对我有用的解决方案：我将 ActiveSupport 作为单独的 gem、forked it 提取，应用了 Thomas 的上述补丁并做了一些额外的修复，因此它可以运行作为 gem，在 rails。我还在 activeadmin 之前添加了这个 gem，所以当需要 Duration 时运行我的补丁版本：

# Gemfile extract
gem 'activesupport', :git => 'git://github.com/beshur/activesupport.git'
gem 'activeadmin', '0.6.6'

然后我将我的 heroku 应用切换为使用 stack heroku-16 (more on stacks here)，但是它仍然需要 ruby 2.3.8.

希望它对以后的人有所帮助，尽管它已经是过时的版本。

Answer 7

我在迁移旧版应用程序时遇到了同样的问题。将 Rails 升级到 4.2 后，您可以将 Ruby 版本升级到 2.4，然后继续升级 Rails 和 Ruby。

我建议在你的 Gemfile 中使用 bootboot gem 这样你就可以在新旧 Rails 版本中测试运行规范，只需要一个环境变量，而不必切换 Git 分支机构.
