使用 git push 將 django 應用程序部署到 heroku 時出現無法識別的錯誤

Question

我有一個具有以下文件結構的 django 應用程序

- project_name
        (settings, __init__, urls, asgi, wsgi ... *.py)
- manage.py
- app_name
        - templates
                (template files)
        - static
                (just some static files)
        (urls, views, apps, models __init__ and the other usual files within django app *.py)

- requirements.txt

我認為我已經在頂級目錄（包含 project_name 和 app_name 子目錄）中運行了所有必要的命令

1. git init
2. heroku git:remote -a (heroku_app_name)
3. git add .
4. git commit -am "this is a commit message"

然后錯誤出現在git push heroku master ，日志如下：

我決定禁用使用heroku config:set DISABLE_COLLECTSTATIC=1收集靜態信息，因為它帶來了更多錯誤，但我認為這不是問題所在。

在提出此問題時，我正在運行最新版本的 Windows 10 Home。

Answer 1

您似乎沒有包含 Heroku 部署的Procfile 。 按照以下指南創建Procfile和設置：

1. 安裝gunicorn庫，它是 Django 和 Flask 應用程序的生產 Web 服務器

pip install gunicorn

2. 將gunicorn添加到您的 requirements.txt 文件中。

pip freeze -r requirements.txt

3. 在應用程序的根目錄中創建一個名為Procfile的新文件。 這是創建Procfile后的文件結構：

- project_name
        (settings, __init__, urls, asgi, wsgi ... *.py)
- manage.py
- app_name
        - templates
                (template files)
        - static
                (just some static files)
        (urls, views, apps, models __init__ and the other usual files within django app *.py)

- requirements.txt
- Procfile

4. Procfile添加到Procfile ：

web: gunicorn projectname.wsgi

注意：將projectname.wsgi行中的“projectname”替換為您的項目名稱

5. 重新部署應用程序
