Question

我在线学习了一个很棒的django教程，但是最后的heroku部署存在问题。

这是django教程： http://gettingstartedwithdjango.com/en/lessons/introduction-and-launch/

我遇到的问题是最后一次调用heroku：

heroku python manage.py syncdb

这是我得到的错误：

(blog-venv)vagrant@precise64:/vagrant/projects/microblog$ heroku run python manage.py syncdb
Running `python manage.py syncdb` attached to terminal... up, run.2530

    return _connect(dsn, connection_factory=connection_factory, async=async)

        Is the server running locally and accepting
        connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?

任何想法

Answer 1

据我所知（git中级知识）如果你忘了将locals.py添加到.gitignore文件并提交它，那么git存储库中的locals.py文件仍然存在。

您必须从git存储库中删除该文件，因为它已包含在先前的提交中。

git rm --cached microblog/settings/local.py

然后将microblog / settings / local.py添加到.gitignore并提交更改。

一旦heroku看到正确的DATABASES设置。然后syncdb工作正常

DATABASES = {'default' : dj_database_url.config() }

Answer 2

你添加了： 微博/设置/ local.py 到.gitignore文件？

如果不起作用，请尝试在local.py文件中注释掉DATABASES = {....}位，看看是否有效
