Heroku 从 github 子文件夹部署

Question

我在 Heroku 上创建了一个 Rails 应用程序，我决定从 github 部署它。由于我的 github 文件夹具有以下结构，如果我选择在 heroku 上从 github 部署，由于子文件夹，它不会识别出我正在使用 ruby​​ on rails。

*\.git
*\otherfiles
*\book-market
*****\app
*****\bin
*****\config
...ecc

我的 rails 应用程序位于 book_market 文件夹中。起初我使用以下命令从 Heroku CLI 推送

git subtree push --prefix book_market heroku master

一切都很好，除了我每次都必须提交和推动这一事实。

昨天我发现了这个构建路径Heroku Buildpack Subdir，它允许你在一个文件夹中执行一个构建路径，所以我在我的根git目录中创建了一个.buildpacks，下面一行

book_market=https://github.com/heroku/heroku-buildpack-ruby.git

我还在根目录中创建了一个Procfile

 web: book_market/bin/bundle exec rails server -p $PORT -e $RAILS_ENV 

来自 github 的部署效果很好，它编译了所有内容，但无法启动服务器并且日志显示

heroku[web.1]: Starting process with command `book_market/bin/bundle exec rails server -p 59500 -e production
heroku[web.1]: Process exited with status 1
heroku[web.1]: State changed from starting to crashed
app[web.1]: /usr/lib/ruby/2.3.0/rubygems.rb:241:in `bin_path': can't find gem bundler (>= 0) (Gem::GemNotFoundException)
app[web.1]:     from book_market/bin/bundle:3:in `<main>'

这是我的宝石文件

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

end
group :development, :test do
  # Call 'byebug' anywhere in the code to stop execution and get a debugger console
  gem 'byebug', platform: :mri
end

我还注意到，当我创建应用程序并使用 subtree 命令推送它时，它会创建不同的环境变量

tiziocaio@gmail.com: Set LANG, RACK_ENV, RAILS_ENV, RAILS_LOG_TO_STDOUT, RAILS_SERVE_STATIC_FILES, SECRET_KEY_BASE config vars

并附上数据库

tiziocaio@gmail.com: Attach DATABASE (@ref:postgresql-solid-35310)

当我从 github 部署时，它没有这样做。

我该如何解决这个问题？谢谢

Answer 1

我解决了这个问题。首先，我更改为this builder-pack，并根据他们的指示将 Procfile 移到了我的子目录中。

关于数据库问题，我只是在 heroku 上添加了 postgresql 插件并配置了所有内容
