节点-使用git将应用程序部署到heroku

Question

I am trying to deploy my app to heroku and I keep getting this error message saying that it "failed to detect app matching ......." and the push was rejected. 我正在尝试将我的应用程序部署到heroku，并且不断收到此错误消息，提示它“无法检测到应用程序匹配.......”，并且推送被拒绝。 I followed the way it said on the heroku website and I keep getting stuck on only that git push heroku master part I have tried doing some research I couldn't find a solution. 我遵循了heroku网站上的说法，但我一直坚持只使用git push heroku master部分，我尝试做一些研究，但找不到解决方案。

This means that a package.json file isn't checked into the root of your git project, so Heroku is detecting that it isn't a Node.js app. 这意味着未将package.json文件检入git项目的根目录中，因此Heroku正在检测到它不是Node.js应用程序。 You can see this locally: 您可以在本地看到此内容：

git show master:package.json

To fix it, you'll want to be sure there is a package.json in the root of your project (where there is also a .git directory), and add it to git: 要修复它，您需要确保在项目的根目录（还有一个.git目录）中有一个package.json，并将其添加到git中：

git add package.json
git commit -m 'track package.json'

The phrasing ('failed to detect set buildpack') could be improved. 措辞（“无法检测到设置的构建包”）可以得到改善。 It should probably say 'failed to detect Node.js app'. 它可能应该说“未能检测到Node.js应用程序”。 When the buildpack's "detect" script is run ( https://github.com/heroku/heroku-buildpack-nodejs/blob/master/bin/detect ), it looks for a package.json file to verify that there's a node app available to build. 运行buildpack的“检测”脚本（ https://github.com/heroku/heroku-buildpack-nodejs/blob/master/bin/detect ）时，它将查找package.json文件以验证是否存在节点应用程序可以建造。
