Git Heroku 错误 [remote rejected] ... (pre-receive hook declined)。

Question

我正试图将本地代码库（repo）推送到我的Heroku服务器上，但每次都会出现以下错误：

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

这是Python版本3.8.0的完整命令行日志：

（这是我第一次使用Git和Heroku，所以如果错误很明显，我很抱歉。）

但是我已经尝试过Python 3.7.5和Python 2.7.17，但两者都无法工作，尽管它们在herokustack-18上被列为支持的。 - stuchlyf

你应该仔细检查你的 runtime.txt 文件；ÿþPython-3.7.5 不符合 https://devcenter.heroku.com/articles/python-runtimes 中的要求。 - jonrsharpe

好的，文档指出它是区分大小写的；还有一些额外的字符来自某个地方。 - jonrsharpe

现在我已经将 runtime.txt 文件名全部改为小写，但在命令行中仍然是 ÿþpython-3.7.5。 - stuchlyf

请参见 https://stackoverflow.com/search?q=%C3%BF%C3%BE - jonrsharpe

Answer 1

在 runtime.txt 文件中，Python 是怎么写的？是 Python 还是 python？我遇到了这个问题：我从 Python-3.8.0 改成了 python-3.8.0，然后它就可以工作了。

Answer 2

对我有效的方法是这个pip freeze > requirements.txt

我意识到我一直忘记添加requirements文件。

之后，请按照以下顺序重复执行。

git add .
git commit -am "make it better"
git push heroku master

- NMukama

Answer 3

在大多数情况下，您只需使用以下方法禁用静态文件配置即可：

heroku config:set DISABLE_COLLECTSTATIC=1

你就可以开始了。

Answer 4

我通过创建 runtime.txt 文件并将我想要的 Python 版本 (python-3.7.11) 写入该文件中，然后将其与 app.py 放置在同一目录下来解决了这个问题。

app.py
Procfile
requirements.txt
runtime.txt

- Om. Sa223

Answer 5

我成功解决了这个问题，以下是我的步骤：

• pip freeze > requirements.txt
• git add .
• git commit -am "make it better"

最后我再次进行了推送：

• git push heroku master

Answer 6

以“remote:”开头的行是远程存储库中的pre-receive hook回显。远程存储库运行hook以在接受您的推送之前检查文件。它尝试构建/解析文件并遇到错误... 您可以在此处找到完整的答案。 Heroku部署问题（[remote rejected] master -> master（pre-receive hook declined）error：failed to push some refs）。

对于我的情况，我正在尝试部署一个flask应用程序，但缺少一个包含必要依赖项的文件。为了纠正错误，我执行了以下操作以生成包含所有依赖项的文件。“pip freeze > requirements.txt”，然后问题就解决了。

以下博客详细介绍了如何在Heroku上部署Flask应用程序。 https://medium.com/the-andela-way/deploying-a-python-flask-app-to-heroku-41250bda27d0

Answer 7

在我的情况下，我意识到我忘记通过终端登录Heroku了。然后我更新了requirements.txt文件。

这是我所做的：

1. heroku login
2. git add .
3. git commit -m "requirements.txt updates"
4. git push heroku master.

它按照我预期的工作了。

Answer 8

查看您的仪表板 -> YOUR_APP -> 活动 -> 查看日志

您可以找到确切的错误消息。

在我的情况下，我发现了这个（查看图片），我不得不删除我的package-lock.json，因为我也有yarn.lock...

- Cristian Guaman

Answer 9

我找到了问题所在。

我认为Heroku不支持我的编码类型，因此它向我的runtime.txt添加了一些奇怪的字符。但是在更改为UTF-8（我想是这个，很久以前了），一切都运行正常。

- stuchlyf

Answer 10

对我有效

首先

$ heroku config:set DISABLE_COLLECTSTATIC=1

之后

$ git push heroku main
