ruby-on-rails - 无法在 Heroku 上启动全新的 Rails 应用程序

Question

尝试使用 heroku 启动一个全新的 rails 项目，按照 https://devcenter.heroku.com/articles/getting-started-with-rails5 中的步骤进行操作和 https://devcenter.heroku.com/articles/getting-started-with-rails6 .两次尝试推送到 heroku master 时，我都得到了

remote: -----> Detecting rake tasks
remote: 
remote:  !
remote:  !     Could not detect rake tasks
remote:  !     ensure you can run `$ bundle exec rake -P` against your app
remote:  !     and using the production group of your Gemfile.
remote:  !     /tmp/build_4403463c/config/boot.rb:5:in `require': cannot load such file -- bootsnap/setup (LoadError)
remote:  !     from /tmp/build_4403463c/config/boot.rb:5:in `<top (required)>'
remote:  !     from /tmp/build_4403463c/bin/rake:7:in `require_relative'
remote:  !     from /tmp/build_4403463c/bin/rake:7:in `<main>'
remote:  !

我试图包围 bootsnap/setup与救援，它仍然击中这个块。

找到了解决办法，在 Gemfile.lock我换了 RUBY VERSION至 ruby 2.6.6p146和 BUNDLED WITH至 1.17.3
