Question

我一直在寻找这个问题一段时间，并且在我的情况下找不到任何似乎适用的东西。我一直在盯着这些日志，我看不出是什么问题。

这在以前的部署过程中发生过，但似乎总是自行解决。现在这只是自己发生的（没有部署），我无法摆脱它。尝试恢复到以前版本的应用程序，但似乎我被卡住了。我重置了dyno并且还完成了rake db：migrate。

日志中有一些重复的东西，但我只是不知道从中读取什么。任何人都知道问题出在哪里？任何指导将不胜感激。请参阅下面的日志。

Answer 1

请尝试以下步骤：

- git push heroku master # if not done
- heroku run rake db:migrate
- heroku restart

等几分钟......

Answer 2

在我的情况下，这是因为我正在硬编码要使用的端口，

我改变了这个，它起作用了

app.listen(process.env.PORT || 3000);

Answer 3

创建一个heroku帐户

 $heroku create

验证你的git configration是否正常

$git remote -v

将Git仓库与现有应用程序相关联

$heroku git:remote -a herokuapp-name

执行push to master

$git push heroku master

要使数据库正常工作，您必须迁移到生产数据库

$heroku run bundle exec rake db:migrate

然后重启

heroku restart

最终浏览到您的位置

Answer 4

您需要在本地编译资产。我经常跑

bundle exec rake assets:precompile

然后提交并推送到heroku。

Answer 5

我在package.json中的主条目指向错误的目录。确保它指向构建输出目录。对于我的情况，我的服务器文件位于 / bin 文件夹中，因此我设置了package.json

{
  "main": "build/bin/www.js"
  "scripts": {
    "start": "node ."
  }
}

Answer 6

在我的情况下，我正在使用babel在ES6上进行快速处理，将babel导入devDependency后（ Heroku忽略了生产中的devDependencies ），然后将它们纳入对我有用的依赖中。 >

"dependencies": {
    "@babel/register": "^7.8.3",
    "@babel/core": "^7.8.4",
    "@babel/preset-env": "^7.8.4"
}

Answer 7

我也遇到了这个错误，总的来说，这个错误意味着它不能与您的依赖项一起使用，原因之一可能是依赖项的旧版本。我通过以下两个步骤解决了这个问题： 1）我手动更新了所有依赖项。 2）我将Flask API从app.py更改为err.py（使用其他名称可能会有所帮助，但这不是必需的。

这对我有用。希望对您有帮助！
