【中文标题】部署到 heroku - 未能检测到 buildpack nodejs (jasonswett)【英文标题】：Deploying to heroku - failed to detect buildpack nodejs (jasonswett) 【发布时间】：2017-01-19 02:35:22 【问题描述】：我正在学习 Jason Swett 的“Angular for Rails 开发人员”一书中的教程。主题在第 2 章：部署。
首先我是这样做的：
$ rm -rf public
$ ln -s client/dist public
然后在 heroku 中创建应用程序后，我添加了 buildpacks
$ heroku buildpacks:add https://github.com/jasonswett/heroku-buildpack-nodejs
$ heroku buildpacks:add heroku/ruby
这是构建包的结果
=== author-wizard Buildpack URLs
1. https://github.com/jasonswett/heroku-buildpack-nodejs
2. heroku/ruby
这是 package.json 文件

如果有任何帮助，我将不胜感激。谢谢。
更新：
我在 rails root 中运行了 git push。这是 ls -la 的输出； ls -la 客户端：
$ ls -la; ls -la client

【问题讨论】：
两个问题：1）运行gp heroku master时，你在哪个文件夹？它是你的 Rails 根吗？ （应该是。） 2）在你的 Rails 根目录下，你能分享这个命令的输出吗？ ls -la;ls -la client
@JasonSwett 更新了我的问题。是的，我在 rails 根文件夹中。
如果您尝试不使用这些说明会怎样？ angularonrails.com/…
【参考方案1】：
试试这个
gp --force heroku master
希望在这里 gp 的意思是git push
【讨论】：
推送成功，构建失败。 远程：！推送失败？检查你的日志 啊，是的，对不起。我尝试使用 --force 但仍然没有运气。以上是关于部署到 heroku - 未能检测到 buildpack nodejs (jasonswett)的主要内容，如果未能解决你的问题，请参考以下文章
