Question

我正在尝试使用Shopify宝石建立在线商店。我已将gem shopify_api添加到Gemfile中，并运行bundle install和bundle update。但是，当我运行下一条命令时：

rails generate shopify_app -api_key=[API_KEY_HERE]-secret=[SECRET_KEY_HERE]

我收到以下错误：

Could not find generator 'shopify_app'. Maybe you meant 'scaffold', 'scss:assets' or 'controller'
Run `rails generate --help` for more options.

我尝试重新启动Rails服务器，但没有任何效果。为什么我会收到此错误，该怎么办？

宝石文件：

source 'https://rubygems.org'

git_source(:github) do |repo_name|
  repo_name = "#{repo_name}/#{repo_name}" unless repo_name.include?("/")
  "https://github.com/#{repo_name}.git"
end

gem 'shopify_api'
# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'

end

end

# Windows does not include zoneinfo files, so bundle the tzinfo-data gem

运行命令rails generate --help时，我得到以下信息

C:\Sites\postgresapp>rails generate --help

编辑：我已经找到了我的问题的部分答案。从Gem文档中指出：

此gem需要从4.3版本开始使用Ruby 2.3.1。如果您需要使用较旧的Ruby版本，然后更新您的Gemfile以锁定到较旧的版本版本高于4.3。

由于我使用的是ruby 2.2.6版，因此需要指定旧版gem。因此我将问题进一步缩小到：我如何知道要使用哪个版本的Shopify宝石？

Answer 1

bundle list将列出您所有的宝石及其版本

bundle list | grep shopify将为您显示有关Shopify宝石的详细信息

Answer 2

我认为您需要将gem 'shopify_app'包含在gemfile中，然后再次捆绑安装。我可以看到您拥有shopify_api宝石，但没有shopify_app宝石，它具有发生器。

为什么生成器在Shopify Gem中不工作？
