Flask 为什么可以'；t heroku运行我的烧瓶应用程序。找不到属性应用程序，然后输出错误代码H10

我已经按照如下方式设置了Procfile:

web:gunicorn项目。main:app

文件夹的主要结构是：

├── DocumentTemplates
├── __pycache__
├── project
├── venv
├── ASLtemplate\ (with\ highlighted\ fields).docx
├── ASLtemplate.docx
├── Procfile
└── requirements.txt

包含应用程序文件（init.py）的项目文件夹的文件结构如下：

├── ASLtemplate.docx
├── __init__.py
├── __pycache__
│   ├── __init__.cpython-37.pyc
│   ├── auth.cpython-37.pyc
│   ├── main.cpython-37.pyc
│   └── models.cpython-37.pyc
├── auth.py
├── db.sqlite
├── main.py
├── models.py
├── static
│   └── css
│       └── main.css
└── templates
    ├── asl.html
    ├── base.html
    ├── index.html
    ├── login.html
    ├── profile.html
    └── signup.html

def create_app():
    app = Flask(__name__)

我已经使用venv建立了一个虚拟环境

init.py设置如下：

├── ASLtemplate.docx
├── __init__.py
├── __pycache__
│   ├── __init__.cpython-37.pyc
│   ├── auth.cpython-37.pyc
│   ├── main.cpython-37.pyc
│   └── models.cpython-37.pyc
├── auth.py
├── db.sqlite
├── main.py
├── models.py
├── static
│   └── css
│       └── main.css
└── templates
    ├── asl.html
    ├── base.html
    ├── index.html
    ├── login.html
    ├── profile.html
    └── signup.html

def create_app():
    app = Flask(__name__)

以下是运行heroku日志的日志--tail：

查看将其指向不存在的

project.main.app（）

的枪图标。基于以下条件，我相信如果您将调用更改为：

gunicorn "project:create_app()"

---

如果这不起作用，您必须提供一个“应在指定模块中找到的WSGI可调用文件”（）。

Hey！查看日志，似乎会有一个错误日志。你能把错误日志的内容添加到你的问题中吗？我现在已经用日志更新了帖子。嘿，这很有帮助。请您也添加

project/uuu init_uuuuuuuuuuupy

和

project/main.py

的内容好吗？我现在已经添加了这两个文件中的代码。在这里你可以找到答案
