的Heroku - 打捆：未能加载命令：麒麟

Question

红宝石2.3.1

的Rails 5.1.2

一直试图通过设置多buildpack应用程序部署我的轨到的Heroku（heroku buildpacks:set https://github.com/heroku/heroku-buildpack-multi.git）与https://github.com/heroku/heroku-buildpack-ruby.git和https://github.com/heroku/heroku-buildpack-nginx.git。当我git push heroku master，它成功地将回购上传到heroku。当我尝试进入网站时，出现应用程序错误页面。所以，我去检查heroku logs，我看到了以下错误：

Starting process with command `bin/start-nginx bundle exec unicorn -c config/unicorn.rb` 
2017-08-10T23:41:44.799815+00:00 app[web.1]: bundler: failed to load command: unicorn (/app/vendor/bundle/ruby/2.3.0/bin/unicorn)

另外，我得到一个恒定的循环以下消息：

2017-08-10T23:42:35.568403+00:00 app[web.1]: buildpack=nginx at=app-initialization 

哪个我会假设它是因为它试图启动与Procfile：

web: bin/start-nginx bundle exec unicorn -c config/unicorn.rb 

unicorn_init.sh：

---答案---

需要添加$PORT到我Procfile。

web: bin/start-nginx bundle exec unicorn -p $PORT -c config/unicorn.rb

Answer 1

如何摆脱的说法错误的：

最好的猜测是，当你使用它git push heroku被推到Heroku的空文件夹pids未正确克隆。

所以我要做的是首先检查，看看它是否存在，如果没有，使用mkdir pids创建它。

如何摆脱无限循环问题的

Forgot to add $PORT inside Procfile
