Django deployment to Heroku error: python: can't open file '/app/backend.manage.py': [Errno 2] No such file or directory , is this a Procfile error?

我正在尝试将一个 django 项目部署到 Heroku，但我遇到了错误，但希望这是最后一个。

当我尝试使用命令 heroku local:

在本地计算机的虚拟环境中 运行 程序时

等等等等。

我怀疑这与我的 Procfile 有关。不可否认，我不太确定如何设置它。我目前在 Procfile:

web: gunicorn --pythonpath backend.feh backend.feh.wsgi --log-file - 
release: python backend.manage.py makemigrations - - no-input

我的目录结构是这样的：

runtime.txt
requirements.txt
Procfile
backend/
    |-- __init__.py
        api/
        feh/
            |-- __init__.py
                errorlog
                settings.py
                urls.py
                wsgi.py
        static/
        db.sqlite3
        manage.py
scraper.py

我肯定我的 Procfile 是导致此问题的原因，但我不知道如何调试它。至少，项目 运行 在我的 venv 上没问题。提前致谢！

您的 Procfile 中的两个进程均未正确指定。

  • Web 命令的 --pythonpath 应该只是 backend 并且它应该接收虚线路径 feh.wsgi 作为参数：

    web: gunicorn --pythonpath backend feh.wsgi --log-file -

  • 释放命令引用了一个名为backend.manage.py的文件：

    release: python backend.manage.py makemigrations - - no-input

    该参数应该是文件的路径，而不是带点的 Python 模块，并且 - - no-input 应该是单个参数 --no-input。试试这个：

    release: python backend/manage.py makemigrations --no-input
