我的 Django 应用程序在本地运行良好,有时推送到 Heroku 是成功的,但 heroku 日志显示错误(并且应用程序无法在线加载)。我的 Procfile 似乎有问题(或者可能是我的 virtualenv,尽管我已经重新做了整个事情来尝试解决这个问题)。
我在我的 Procfile 中尝试了很多版本:
web: python manage.py collectstatic --noinput; bin/gunicorn_django --workers=4 --bind=0.0.0.0:$PORT proj/prod_settings.py
和这个:
web: python manage.py runserver 0.0.0.0:$PORT collectstatic --noinput
--settings=proj/prod_settings.py
和这个:
web: gunicorn bookfairy.wsgi.py
但我不断收到这样的错误:
-foreman start pid 17199 result: no such option: --noinput
-foreman start pid 17229 result: no such option: --workers
-foreman start pid 17299 result: Could not import settings 'proj/prod_settings.py' (Is it on sys.path?): Import by filename is not supported.
-Push failed: slug archive could not be created
! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to heroku
-foreman start pid 16943 result: Error: Usage is runserver [optional port number, or ipaddr:port]
-Process exited with status 1

psycopg2.OperationalError: could not connect to server: Connection refused
Is the server running on host "localhost" (127.0.0.1) and accepting
TCP/IP connections on port 5432?
我能想到的事情是我尝试过的:
- 删除并替换了我的 Procfile(大写,是的)
- 完成 pip freeze 到我的 requirements.txt 文件
- 添加了一个 runtime.txt 文件
- 开始了测功机
- 遵循所有 Heroku Django 指令
- 重新安排我的目录结构(并将我的 wsgi.py 文件移动到与 requirements.txt 相同的文件夹)
- 试过 run_gunicorn (未知命令错误)
- pip 安装了所有依赖项(两次,包括 Django、psycopg2、dj-database-url)
- heroku run python manage.py syncdb (服务器是否在主机“localhost”(127.0.0.1)上运行并接受端口 5432 上的 TCP/IP 连接?)
- 检查 Postgres 和 Heroku 工具带安装
我将非常感激能得到一些帮助。
