Question

这是我的sinatra应用程序的目录结构

➜  app-fin git:(master) ls
public/  views/  birthday_countdown.rb  config.ru  Gemfile  Gemfile.lock  Procfile  web.rb

我的Gemfile是

source 'https://rubygems.org'

gem 'sinatra'
gem 'thin'

Procfile

web: bundle exec ruby web.rb -p $PORT

和config.ru

$:.unshift File.expand_path("../", __FILE__)
require './web'
run Sinatra::Application

当我尝试推送到heroku时，我收到此错误，

我很困惑为什么它认为我的应用程序应该使用node.js，有没有人有任何想法如何说服heroku它实际上是一个sinatra应用程序。

Answer 1

您是否有可能在创建应用时指定了node.js buildpack？

https://devcenter.heroku.com/articles/buildpacks

由于你有一个合适的Gemfile，它应该首先被ruby buildpack检测到。此外，由于您没有package.json文件，因此不应检测到Node.js.

Heroku将我的sinatra应用程序检测为node.js应用程序并失败
