Heroku code=H10 desc=“应用崩溃”--找不到崩溃的原因

Question

我已经在这个问题上寻找了一段时间，没有找到任何适合我的情况的东西。我一直在看这些日志，但我看不出问题出在哪里。

这在以前的部署过程中也发生过，但似乎总是会自行解决。现在，这是它自己发生的(没有部署)，我无法摆脱它。尝试恢复到该应用程序的前一个版本，但似乎我卡住了。我已经重置了dyno，还做了一个rake db:migrate。

日志中有一些重复的东西，但我就是不知道从它们中读出什么。有人知道问题出在哪里吗？任何指导都将不胜感激。请参阅下面的日志。

Answer 1

尝试执行以下步骤：

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

等几分钟...

Answer 2

在我的例子中，这是因为我硬编码了要使用的端口，

我用这个进行了修改，它起作用了。

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

Answer 3

创建heroku帐户

 $heroku create

验证您的git配置是否正确

$git remote -v

将Git存储库与现有应用程序关联

$heroku git:remote -a herokuapp-name

执行推送到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

然后重新启动

heroku restart

最后浏览到您的位置
