[英]unable to push node.js app on heroku
我嘗試在 heroku 上推送我的 node.js 應用程序,但是。 無法檢測到此應用的默認語言。 我什至嘗試過 heroku buildpacks:set heroku/nodejs。 但是還是推不動。

根據您的日志,Heroku 似乎無法檢測您的應用程序的語言。
對於 Node.js,您需要在項目的根目錄中創建一個package.json
文件(使用類似npm init
東西),或者您可以在項目的根目錄中創建一個Procfile
來指定您的語言:
web: node index.js
轉到命令行並運行以下命令:
heroku buildpacks:set -a app_name heroku/node
