Heroku Deploy: URI::InvalidURIError: bad URI(is not URI?): ://user:pass@127.0.0.1/dbname

Question

我有一个带有 Vue 前端和 rails 后端的项目。它只是一个非常简单的后端 API ，没有数据库或任何东西。它在本地运行良好，但现在我想将它部署到 Heroku 上。

但是，当我运行它时，我得到以下错误。

-----> Detecting rake tasks
 !
 !     Could not detect rake tasks
 !     ensure you can run `$ bundle exec rake -P` against your app
 !     and using the production group of your Gemfile.
 !     rake aborted!
 !     URI::InvalidURIError: bad URI(is not URI?): ://user:pass@127.0.0.1/dbname
  ...
  ...
/activerecord-6.0.2.1/lib/active_record/railties/databases.rake

基于各种 SO posts/Heroku 文档，我已经尝试过：

bundle exec rake -P RAILS_ENV=production - 一切正常
在 Gemfile 中添加 rake 依赖项
删除 Gemfile 中的 sqlite 依赖项
从 Gemfile.lock

但是还是一样的错误

我想这与我的数据库配置有关，但我的项目中没有任何数据库，所以这似乎是一项不必要的任务。我尝试从我的 Gemfile 中注释掉 railties，但它仍然作为其他 gem 的依赖项存在。当我在进行此更改后进行部署时，它仍然执行相同的任务但失败了。

Link 到 repo branch

而不是 require 'rails/all' 需要所有 Railties 包括 ActiveRecord 你需要明确地要求你想使用的 railties:

require File.expand_path('../boot', __FILE__)

# Require the gems listed in Gemfile, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(*Rails.groups)

require "rails"
# Pick the frameworks you want:
require "active_model/railtie"
require "active_job/railtie"
# require "active_record/railtie"
# require "active_storage/engine"
require "action_controller/railtie"
require "action_mailer/railtie"
require "action_mailbox/engine"
# require "action_text/engine"
require "action_view/railtie"
require "action_cable/engine"
require "sprockets/railtie"

module Draw
  class Application < Rails::Application
    # You don't need this nonsense since you don't even have config/application.yml
    #  ENV.update YAML.load_file('config/application.yml')[Rails.env] rescue {}
    # Settings in config/environments/* take precedence over those specified here.
    # Application configuration should go into files in config/initializers
    # -- all .rb files in that directory are automatically loaded.

    # Set Time.zone default to the specified zone and make Active Record auto-convert to this zone.
    # Run "rake -D time" for a list of tasks for finding time zone names. Default is UTC.
    # config.time_zone = 'Central Time (US & Canada)'

    # The default locale is :en and all translations from config/locales/*.rb,yml are auto loaded.
    # config.i18n.load_path += Dir[Rails.root.join('my', 'locales', '*.{rb,yml}').to_s]
    # config.i18n.default_locale = :de

    # Do not swallow errors in after_commit/after_rollback callbacks.
    # config.active_record.raise_in_transactional_callbacks = true
  end
end

如果您不想使用 ActiveRecord，您可以去掉 /db 和 /config/database.yml。

您也不需要在 Gemfile 中添加 have gem 'rake'，因为 rails 无论如何都依赖于它。

Answer 2

需要从项目中完全删除对 ActiveRecord 的使用。作为, in a new app this can be done by doing rails new app_name --skip-active-record --api, to do this for an existing project see
