為什么我的Django應用程序在本地工作，而不是在Heroku上工作？

Question

我的Django應用程序在本地工作正常，有時推送到Heroku是成功的，但heroku日志顯示錯誤（並且應用程序不會在線加載）。 似乎我的Procfile（或者也許是我的virtualenv）有問題，盡管我已經重新做了整件事以試圖解決這個問題。

我在我的Procfile中嘗試了很多這個版本：

web: python manage.py collectstatic --noinput; bin/gunicorn_django --workers=4 --bind=0.0.0.0:$PORT proj/prod_settings.py

和這個：

web: python manage.py runserver 0.0.0.0:$PORT collectstatic --noinput
--settings=proj/prod_settings.py

和這個：

web: gunicorn bookfairy.wsgi.py

但我不斷收到這樣的錯誤：

-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
State changed from starting to crashed
-heroku[router]: at=error code=H10 desc="App crashed" method=GET path=/robots.txt     host=bookfairy.herokuapp.com fwd="66.249.72.200" dyno= connect= service= status=503 bytes=

和這個：

    File "manage.py", line 10, in <module>
    execute_from_command_line(sys.argv)
  File "/app/.heroku/python/lib/python2.7/site-packages/django/core/management/__init__.py", line 443, in execute_from_command_line
    utility.execute()

  File "/app/.heroku/python/lib/python2.7/site-packages/django/core/management/base.py", line 196, in run_from_argv
    self.execute(*args, **options.__dict__)

    output = self.handle(*args, **options)
  File "/app/.heroku/python/lib/python2.7/site-packages/django/core/management/base.py", line 371, in handle
    return self.handle_noargs(**options)
  File "/app/.heroku/python/lib/python2.7/site-packages/django/core/management/commands/syncdb.py", line 57, in handle_noargs
    cursor = connection.cursor()
  File "/app/.heroku/python/lib/python2.7/site-packages/django/db/backends/__init__.py", line 317, in cursor
    cursor = self.make_debug_cursor(self._cursor())
  File "/app/.heroku/python/lib/python2.7/site-packages/django/db/backends/postgresql_psycopg2/base.py", line 177, in _cursor
    self.connection = Database.connect(**conn_params)
  File "/app/.heroku/python/lib/python2.7/site-packages/psycopg2/__init__.py", line 164, in connect
    conn = _connect(dsn, connection_factory=connection_factory, async=async)
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?

我能想到的事情我嘗試過：

• 刪除並替換我的Procfile（大寫，是）
• 完成pip凍結到我的requirements.txt文件
• 添加了runtime.txt文件
• 開始了一個dyno
• 遵循所有Heroku Django指令
• 重新安排我的目錄結構（並將我的wsgi.py文件移動到與requirements.txt相同的文件夾）
• 試過run_gunicorn（未知命令錯誤）
• pip安裝了所有依賴項（兩次，包括Django，psycopg2，dj-database-url）
• heroku運行python manage.py syncdb（服務器是否在主機“localhost”（127.0.0.1）上運行並接受端口5432上的TCP / IP連接？）
• 檢查Postgres和Heroku工具帶安裝

我非常感謝能得到一些幫助。

Answer 1

命令python manage.py runserver 0.0.0.0:$PORT collectstatic --noinput無效，你試圖在一個中做兩件事。

python manage.py runserver 0.0.0.0:$PORT

python manage.py collectstatic --noinput

將它們分開作為單獨的命令，我建議將runserver放在Procfile中並在shell中運行collectstatic 。
