尝试在Heroku上部署Rails应用时出错

Question

I keep getting

App not compatible with buildpack: https://buildpack-registry.s3.amazonaws.com/buildpacks/heroku/ruby.tgz
       More info: https://devcenter.heroku.com/articles/buildpacks#detection-failure
 !     Push failed

when I try to deploy my Rails application.

I already have a package.json file in my root directory.

I already have a Gemfile in my root directory.

I already set my buildpack to heroku/ruby .

This is a picture of the full error on the Heroku dashboard:

Here's the repo if that helps: https://github.com/TrentCodes/AboutMeWebsite.git

No you don't: they're in a folder called aboutmewebsite/ .

You need to move everything that's in that directory up to the root directory (the folder that currently contains README.md and aboutmewebsite/ ).

I already set my buildpack to heroku/ruby .

You'll also need the Node.js buildpack if you intend to have dependencies from your package.json installed. Something like

heroku buildpacks:add --index 1 heroku/nodejs

should do it. Run heroku buildpacks afterwards to make sure that the Node.js buildpack is first and the Ruby buildpack is second.
