“Heroku推送被拒绝，没有检测到Cedar支持的应用程序”当试图用现有的git repo上传Sinatra应用程序时 [英] "Heroku push rejected, no Cedar-supported app detected" when trying to upload a Sinatra app with an existing git repo
问题描述
我的个人网站有一个现有的git repo，我正在将它移植到Sinatra（主要用于模板，它是一个静态网站）。我不想丢失/重置此git存储库。
I have an existing git repo for my personal website, which I am porting to Sinatra (mainly for templating, it's a static site). I do NOT want to lose/reset this git repository.
当我尝试推送到Heroku时，出现下面的错误。我有一个config.ru文件，一个Gemfile和一个Gemfile.lock，以及其他一些Sinatra的东西。运行 rackup 工程，运行 bundle exec rackup 可以工作，并且我没有收到Heroku有关丢失依赖关系的任何警告。
When I try to push to Heroku, I get the error below. I have a config.ru file, a Gemfile, and a Gemfile.lock, along with some other stuff for Sinatra. Running rackup works, running bundle exec rackup works, and I didn't get any warnings from Heroku about missing dependencies.
我错过了什么吗？

推荐答案
问题解决了。我正在开发一个git分支，特别是Heroku / Sinatra支持，结果证明我正在运行 git push heroku master ，这会将本地主服务器推送到远程主服务器。主分支没有有效的Heroku应用程序。我认为它会将当前的本地分支推送到远程主分支，事实并非如此。 git push sinatra：master 解决了这个问题。
Problem solved. I was working on a git branch especially for Heroku/Sinatra support, and it turns out I was running git push heroku master, which pushed local master to remote master. The master branch did not have a valid Heroku app. I assumed it would push the current local branch to the remote master branch, which is not the case. git push sinatra:master solved the issue.
