Question

TL; DR：

我应该使用docx gem，而不是（较旧的）docx_converter。这似乎与Rails 5.2更加兼容。

我正在学习Rails，并且有一个有效的应用程序。但是，当我将gem docx_converter添加到我的Gemfile中（以便将Word文件转换为markdown以便进一步处理）时，服务器无法启动。

该应用程序具有三种模型：Company（具有多个用户）和has_many（多个项目）。（用户由Devise控制，公司通过用户拥有多个项目。）当用户创建项目时，他们可以使用active_storage将文件上传到该项目，并且该文件存储在我的开发环境中的磁盘上（这是我所关心的）在这里）。

我对以上任何内容都没有问题-我可以创建用户和项目，并可以从项目中添加和删除文件。

但是，如果我将gem 'docx_converter'添加到我的Gemfile中并运行bundle update，则无法再运行rails服务器。在此操作之前，一切都很好。之后，服务器将无法运行，回溯（最后几行）为：

鉴于引导程序的引用，我尝试将其从Gemfile和config / boot.rb中删除，但这导致在同一位置（但与发布者有关）的相同错误：

我尝试通过“ gem install publishr”安装发布服务器，但这无济于事。

我的Gemfile是：

source 'https://rubygems.org'
git_source(:github) { |repo| "https://github.com/#{repo}.git" }

ruby '2.6.2'

gem 'rails', '~> 5.2.3'
gem 'puma', '~> 3.11'
gem 'sass-rails', '~> 5.0'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails', '~> 4.2'
gem 'turbolinks', '~> 5'
gem 'jbuilder', '~> 2.5'
gem 'bcrypt', '~> 3.1.7'
gem 'bootsnap', '>= 1.1.0', require: false

# Manually added gems
gem 'will_paginate', '~> 3.1.6'
gem 'devise', '~> 4.6.2'
gem 'cancancan', '~>3.0.1'
gem 'docx_converter', '~>1.0.0'

group :development, :test do
  gem 'sqlite3'
  gem 'byebug', platforms: [:mri, :mingw, :x64_mingw]
  gem 'faker', '~> 1.7.3'
end

group :development do
  gem 'web-console', '>= 3.3.0'
  gem 'listen', '>= 3.0.5', '< 3.2'
  gem 'spring'
  gem 'spring-watcher-listen', '~> 2.0.0'
end

这个gem和Rails 5.2.3似乎存在问题，但是没有人知道这里发生了什么以及如何使它工作吗？（或者，也可以使用其他gem来将Word docx文件转换为可用的文件）

Answer 1

bootsnap可能在所有这些方面都可以发挥作用，因为它与Rails的启动混乱。尝试确保清除了所有弹簧过程ps -ef | grep spring。移除bootsnap宝石和bundle install。然后尝试再次rails s启动服务器。

Answer 2

经过一定数量的钻探后，我发现我需要明确地需要两个额外的gem才能使docx_converter正常工作，并且还必须锁定其中一个的版本。

gem 'publishr'
gem 'rubyzip', '~>0.9.9'
gem 'docx_converter', '~>1.0.0'

我还没有对功能进行详尽的测试，但是至少服务器现在可以启动了！谢谢大家的建议！

即使在服务器运行后，我也遇到了这个问题-正如@engineersmnky所说，它很旧，文档记录很差。因此，我已切换到docx gem，它并没有尝试做很多事情，但是看起来（a）可以在Rails 5.2上毫无问题地加载并且（b）可以正常工作！

添加gem docx_converter
