无法推送heroku上的node.js应用程序

我试着在heroku上推送我的node.js应用程序。 没有默认的语言可以检测到这个应用程序。 我甚至尝试过heroku buildpack:设置heroku / nodejs。 但仍然无法推动。

根据您的日志,看起来Heroku无法检测到您的应用程序的语言。

对于Node.js,您需要在您的项目的根目录(使用npm init类的东西)中创build一个package.json文件,或者您可以在项目的根目录下创build一个Procfile来指定您的语言:

 web: node index.js 

转到命令行并运行以下命令:

 heroku buildpacks:set -a app_name heroku/node
