如何在我的 Sinatra 应用程序中使用我的 Ruby gem 中的模块

Question

我正在研究一个未发布的gem，它在Rails中工作正常。它有一个模块需要包含在 ActiveRecord：：Base 类中。

我的Sinatra应用程序看起来像这样：

# app.rb
require 'rubygems'
require 'sinatra'
require 'sinatra/activerecord'
set :database, "sqlite3:project-name.sqlite3"
get '/' do
@users = User.all
erb :index
end
class User < ActiveRecord::Base
end

我的 gem 文件如下所示：

source 'https://rubygems.org'
gem 'activerecord'
gem 'sinatra-activerecord'
gem 'sqlite3'
gem 'rake'
gem "my_module", path: "../my_module"

我的 Gemfile.lock 看起来像这样：

PATH
remote: ../my_module
specs:
my_module (1.49.0)
activerecord (>= 4.2)
GEM
remote: https://rubygems.org/
specs:

zeitwerk (2.2.2)
PLATFORMS

DEPENDENCIES

2.0.2

如果我手动添加模块，它可以正常工作：

# app.rb
require 'rubygems'
require 'sinatra'
require 'sinatra/activerecord'
set :database, "sqlite3:project-name.sqlite3"
get '/' do
@users = User.all
erb :index
end
module MyModule
extend ActiveSupport::Concern
class_methods do
#something here
end
end
class User < ActiveRecord::Base
include MyModule
end

我希望能够做到：

# app.rb
require 'rubygems'
require 'sinatra'
require 'sinatra/activerecord'
require 'my_module'
set :database, "sqlite3:project-name.sqlite3"
get '/' do
@users = User.all
erb :index
end
class User < ActiveRecord::Base
include MyModule
end

我收到错误

cannot load such file -- my_module (LoadError) 

当我使用require语句或

uninitialized constant User::MyModule (NameError)

如果我删除require.

如果我使用

bundle exec ruby app.rb

而不是

ruby app.rb
