Question

我正在尝试在Heroku上创建一个Django应用程序，详见Heroku / Django Cedar堆栈教程。

我已经达到了在Heroku上部署代码的程度，但是当我运行heroku run python appname/manage.py syncdb时，我得到以下跟踪：

Traceback (most recent call last):


File "planamo/manage.py", line 10, in <module>
    execute_from_command_line(sys.argv)
  File "/app/.heroku/venv/lib/python2.7/site-packages/django/core/management/__init__.py", line 443, in execute_from_command_line
    utility.execute()
  File "/app/.heroku/venv/lib/python2.7/site-packages/django/core/management/__init__.py", line 382, in execute
    self.fetch_command(subcommand).run_from_argv(self.argv)

    output = self.handle(*args, **options)

    return self.handle_noargs(**options)
  File "/app/.heroku/venv/lib/python2.7/site-packages/django/core/management/commands/syncdb.py", line 57, in handle_noargs
    cursor = connection.cursor()
  File "/app/.heroku/venv/lib/python2.7/site-packages/django/db/backends/__init__.py", line 308, in cursor
    cursor = util.CursorWrapper(self._cursor(), self)
  File "/app/.heroku/venv/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/venv/lib/python2.7/site-packages/psycopg2/__init__.py", line 179, in connect
    connection_factory=connection_factory, async=async)
psycopg2.OperationalError: could not connect to server: No such file or directory
    Is the server running locally and accepting
    connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?

我不知道问题是什么。发生了什么事？

Answer 1

回答了我自己的问题：你必须运行heroku addons:add shared-database

Answer 2

我刚发现了这个错误的另一个原因。 Heroku在settings.py文件的末尾注入代码。

如果settings.py的最后一行不包含进位返回注入代码，则可以忽略。

这是django-social-auth's settings.py file

的情况

Answer 3

您可以尝试在settings.py中的数据库配置中添加：'HOST'：'127.0.0.1'

在heroku上为我的Django应用程序运行'syncdb'会引发错误
