我的烧瓶 Heroku 尝试失败，我无法查明问题所在

Question

所以我尝试使用 Heroku 为运行制作一个非常简单的测试应用程序。这是我从头开始的第三次尝试。我有一个 python 文件，内容非常少

from flask import Flask

app = Flask(__name__)

@app.route("/")
def test():
    return "test"

if __name__ == '__main__':
    app.run()

文件名为test.py，我的目录还包括Procfile

web: gunicorn app:test

和requirments.txt

click==7.1.2
Flask==1.1.2
gunicorn==20.1.0
itsdangerous==1.1.0
Jinja2==2.11.3
MarkupSafe==1.1.1
Werkzeug==1.0.1

最重要的是，我 git忽略以确保 IDE 文件不会干扰，

.idea
.Heroku.iml

和runtime.txt

python-3.6.0

然后我尝试使用

创建一个应用程序

heroku create <appname>

然后我在命令

中使用第二个URL它returns

git remote add heroku <url>

。然后我做

git add . 
git commit -m "some message"
git push heroku main

并得到以下错误。

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

然后我尝试使用

git push heroku master

相反，但没有发生任何变化。我还尝试强制它使用 python build pack 和

heroku buildpack:set heroku/python --app <appname>

如上错误所述

Building on the Heroku-20 stack
remote: -----> Using buildpack: heroku/python
remote: -----> App not compatible with buildpack: https://buildpack-registry.s3.amazonaws.com/buildpacks/heroku/python.tgz
remote:        More info: https://devcenter.heroku.com/articles/buildpacks#detection-failure

我主要不知道如何使用 git，但我的朋友建议我创建远程存储库并将其附加到 Heroku，但我找不到如何执行附件。

如果有人知道是什么原因造成的和/或如何解决它，如果您能分享这些知识，我将不胜感激。

更新：

感谢您指出需求文件的错误名称，我已将其重命名。我还将我的 Procfile 更改为

web: gunicorn test:app

。遗憾的是它没有解决问题（是的，我确实提交并推动了所做的更改）。以下是错误消息：

对于 git push heroku master :

这里是 git heroku push main:

.

更新好吧，对不起大家，我一般都是弱智。我错过了关于重建错误的明显部分，here 它说明了我的应用程序运行所需的最终修复。

Answer 1

问题是您必须使用

web: gunicorn test:app

而不是

web: gunicorn app:test

正确的格式是

gunicorn <filename>:<app object>
