Heroku 在尝试推送 React 应用程序时“未能推送一些 refs”

Question

通过这个：https://dev.to/smithmanny/deploy-your-react-app-to-heroku-2b6f，我正在尝试从 create-react-app 到 Heroku 部署一个开箱即用的简单反应应用程序。

npx create-react-app my-app
cd my-app
npm install

然后将这些添加到 package.json：

"engines": {
    "npm": "6.12.0",
    "node": "10.16.3"
},

然后：

heroku login blah...
git init
git add .
git commit -m "initial commit"
heroku create
git remote add heroku https://git.heroku.com/damp-spire-48480.git (auto-generated name of app)
git push heroku master

然后我明白了：

error: failed to push some refs to 'https://git.heroku.com/damp-spire-48480.git'

我现在查看了一些 SO 页面，但到目前为止还没有找到解决方案。我不应该说我在那里有几个应用程序和遥控器，但我认为我已经删除了所有应用程序和遥控器，并尝试从头开始......除非还有其他东西需要清理......

我试过这个：Push to Heroku denied - "failed to push some refs to 'heroku"。所以我尝试了：git push heroku master:master 和git push heroku HEAD:master，每次都得到相同的结果。

Answer 1

如果其中有一个，而您稍后将其删除，那么它仍然会失败。

它不应该，如果你删除它并提交，记录删除：

如 Heroku 页面“Why is my Node.js build failing because of conflicting lock files?”中所述

git rm yarn.lock
git commit -m "Remove yarn lock file"
git push heroku master

和/或

git rm package-lock.json
git commit -m "Remove npm lock file"
git push heroku master
