Rails 部署到 Heroku 时出现抽成问题
Rails rake issue when deploying to Heroku
解决方案：我 运行ning ruby 2.6.6p146 与 Bundler 版本 2.2.4。根据@thiebo 的建议，我降级到 Bundler 2.1.2 并且成功了！步骤：
- $ gem 卸载捆绑器
- [然后删除Gemfile.lock]
- $ gem 安装捆绑器 --version '2.1.2'
我已经尝试了这些选项，但没有任何效果：
我确实可以 运行 bundle exec rake -P against my app
我尝试拯救 Rakefile，并在我的 Gemfile 中将 rspec 投入生产：
我在 gem 文件中添加了 'rake'。
尝试添加 gem 'rack-timeout':
我也关注了这个帖子，但无济于事：https://github.com/rubygems/bundler/issues/3640
这是错误：
Bundle completed (36.93s)
Cleaning up the bundler cache.
