LoadError: 无法加载此类文件 -- 升级后运行任何 rails 命令时出现 zip/zip

如何解决LoadError: 无法加载此类文件 -- 升级后运行任何 rails 命令时出现 zip/zip

我刚刚升级到 rails 6，在运行 rails app:update

时我得到以下信息

rails aborted!
LoadError: cannot load such file -- zip/zip
/home/ben/code/app/config/application.rb:7:in `<top (required)>'
/home/ben/code/app/Rakefile:5:in `<top (required)>'
bin/rails:4:in `<main>'
(See full trace by running task with --trace)

我已经更新了所有的 gem，它正在捆绑和更新 gem，gemfile.lock 看起来也不错。

这是回溯：

Error:[rake --tasks] rake aborted!
LoadError: cannot load such file -- zip/zip

这是应用程序.rb

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)
require 'net/http'
require 'csv'

module RailsUpgrade
  class Application < Rails::Application
    # Initialize configuration defaults for originally generated Rails version.
    config.load_defaults 5.0

    # 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.

    config.time_zone = 'London'
    #WARNING: This changes the way times are stored in the database (not recommended)
    config.active_record.default_timezone = :local

    config.log_level = :debug
    config.enable_dependency_loading = true
    config.eager_load_paths << Rails.root.join('lib')

    config.assets.enabled = true
    config.assets.version = '1.0'

    config.filter_parameters << :password
    config.filter_parameters << :password_confirmation
    config.filter_parameters << :card_number
    config.filter_parameters += [:password,:password_confirmation,:card_number]

    # config.middleware.use 'CatchJsonParseErrors'
  end
end

上次运行 rails app:update 是在今天早些时候更新到 Rails 5.2 时。所以不确定是什么问题。

谢谢。

解决方法

您使用的是 axlsx 版本 1.3.6，其中包括 this line: require 'zip/zip'。这就是您的错误消息所指向的内容：

/home/ben/.rbenv/versions/2.5.0/lib/ruby/gems/2.5.0/gems/axlsx-1.3.6/lib/axlsx.rb:26:in `<top (required)>'

但是，我怀疑您也不经意地将 rubyzip gem 升级到 v1.0.0+ - API 已更改，您现在只需要 {{1 }},(不 require 'zip').

有一些解决方案，例如在 the project README 或 this similar StackOverflow question 中提到的：

将 require 'zip/zip' 降级回 rubyzip。
升级v0.x。
将 axlsx 添加到您的 gem 'zip-zip'。
