问题：将Django项目部署到Heroku

Question

我尝试将django应用程序部署到heroku，但出现错误：

remote: Compressing source files... done.
remote: Building source:
remote: 
remote: -----> Building on the Heroku-20 stack
remote: -----> Using buildpack: heroku/python

 ! [remote rejected] master -> master (pre-receive hook declined)
error: не удалось отправить некоторые ссылки в «https://git.heroku.com/tandt-online-webchat.git»

我做了所有需要的事情： git添加。 git commit-m“relize heroku vers 1” 当我推heroku master的时候，我得到了这个错误

我有所有需要的文件：Procfile和requirements.txt 在Procfile中，我有：web:gunicorn web_chat.wsgi和to requirements.txt，我输入pip freeze，然后舒尔我有什么gunicorn她

我做错了什么

Answer 1

一个常见的错误是您的requirements.txt文件有误。另一个可能发生的错误是，你的承诺已经非常错误。为此，请在本地重新初始化git存储库。然后确保添加了requirements.txt文件。你可以跟我核对一下

git status

如果这仍然不起作用，请让我知道

谢谢，但我并不完全了解你。我的setings.py文件到此结束sam有什么问题吗

# Static files (CSS, JavaScript, Images)
# https://docs.djangoproject.com/en/3.1/howto/static-files/

STATIC_URL = '/static/'
# STATIC_ROOT = BASE_DIR/ 'static'

STATICFILES_DIRS = [
    BASE_DIR/ 'asets',
]
STATIC_ROOT = os.path.join(BASE_DIR, 'static')

MEDIA_URL = '/media/'
MEDIA_ROOT = BASE_DIR / 'media'

django_heroku.settings(locals())

Answer 3

是的，这是很多人面临的另一个问题。在settings.py文件中

STATIC_ROOT = os.path.join(BASE_DIR, "static")

这允许Heroku将静态文件存储在git存储库的“static”文件夹中。“设置”文件夹中必须已有静态url。否则：

STATIC_URL = '/static/

此外，如果你有任何其他问题，试着编辑你原来的问题，而不是问一个新的问题，因为这有时会扩展页面太多
