正如你所看到的，尽管我在package.json中指定了我的节点和npm版本，但Heroku没有识别它，我的推送被拒绝了。我试着在Heroku网站上订票，但由于这是一个免费的应用程序，他们不允许我在他们的帮助热线上询问。
edit
我通过Heroku将npm和节点版本升级到默认版本，但我得到了错误Could not find a required file.Name: index.html
我遇到了同样的问题。看起来Heroku还不支持12.16.2。请尝试使用package.json引擎部分中的12.16.1。
更改此
"发动机"：{"节点"："12.16.2"，"npm"："6.13.4"}，
至
"发动机"：{"节点"："12.16.1"，"npm"："6.14.4"}，
成功部署您的应用程序。您应该首先在项目文件夹的根目录中创建一个特定的文件，该文件的名称必须为.
Procfile
没有任何额外的扩展。Procfile文件的内容必须是web: node index.js或任何你的主文件。不要使用web: node run index.js，只有web: node index.js可以。
我的package.json没有"发动机"；指定
添加"发动机"：{"节点"："12.16.1"、"npm"："6.14.4"}，在我的包中.json修复了
