部署到heroku - 未能檢測到buildpack nodejs（jasonswett）

我正在關注Jason Swett的「Angular for Rails Developers」一書中的教程。主題在第2章：部署。部署到heroku - 未能檢測到buildpack nodejs（jasonswett）

首先，我這樣做：

$ rm -rf public 
$ ln -s client/dist public

然後在Heroku上創建應用程序後，我加入了buildpacks

$ heroku buildpacks:add https://github.com/jasonswett/heroku-buildpack-nodejs 
$ heroku buildpacks:add heroku/ruby

這裏是builpacks結果

=== author-wizard Buildpack URLs 
1. https://github.com/jasonswett/heroku-buildpack-nodejs 
2. heroku/ruby

這是package.json文件

     "license": "MIT", 
     "angular-cli": {},

     "pree2e": "webdriver-manager update",

     },

     "typings": "^0.8.1" 
     }, 
     "devDependencies": { 

     } 
    }

當我被推到Heroku上：

$ gp heroku master 
Counting objects: 54, done.

Compressing objects: 100% (47/47), done.

! [remote rejected] master -> master (pre-receive hook declined) 
error: failed to push some refs to 'https://git.heroku.com/author-wizard.git'

我希望得到任何幫助。謝謝。

更新：

我在軌根中運行了git push。這是ls -la的輸出; LS -la客戶端：

兩個問題：1）什麼是文件夾，當你運行'GP的Heroku master'的嗎？它是你的Rails根？（應該是）2）在你的Rails根目錄下，你能分享這個命令的輸出嗎？ 'ls -la; ls -la client' –

@JasonSwett更新了我的問題。是的，我在rails根目錄下。 –

如果您嘗試按照這些說明進行操作，該怎麼辦？ https://www.angularonrails.com/deploy-rails-application-angular-cli-webpack-front-end/ –

這裏試試這個

gp --force heroku master

希望GP就是git push

推動它成功，該建築失敗。 –

遙控器：！推送失敗？檢查你的日誌 – Arvind

啊對不起。我嘗試過使用 - 但仍然沒有運氣。 –
