Question

我正在尝试将MEAN应用程序部署到Heroku，但由于以下错误而无法推送：

 !     No default language could be detected for this app.
        HINT: This occurs when Heroku cannot detect the buildpack to use for this application automatically.
        See https://devcenter.heroku.com/articles/buildpacks
!     Push failed

我尝试使用最新的节点buildpack版本设置node.js buildpack，但刚收到另一个错误：

failed to detect buildpack

这是我第一次部署到Heroku，所以我在这方面是全新的。

这是我的package.jsons：

为什么Heroku没有检测到Node？

Answer 1

根据Heroku documentation

要确定如何启动您的应用，Heroku首先会查找Procfile。如果Node.js应用程序不存在Procfile，我们将尝试启动通过package.json中的启动脚本进行默认Web处理。

所以你不需要设置构建包。

Answer 2

我有两个package.jsons，一个用于客户端，一个用于服务器。我需要将我的服务器依赖项放入根文件夹（它们分别嵌套在客户端和服务器文件夹中）。将它移动到root中使它可以被heroku检测到。当然，现在我有一个新的错误。：）

无法将MEAN应用程序部署到Heroku，因为“此应用程序无法检测到默认语言”。
