我在网上完成了一个很棒的 django 教程，但是在最终的 heroku 部署中遇到了问题。

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
Traceback (most recent call last):

    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"?

有什么想法吗

据我所知（git 中级知识） 如果您忘记将 locals.py 添加到 .gitignore 文件并提交它，那么 git 存储库中仍会有 locals.py 文件。

您必须从 git 存储库中删除该文件，因为它包含在以前的提交中。

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() }

您是否将： microblog/settings/local.py添加 到 .gitignore 文件中？

如果这不起作用，请尝试注释掉 local.py 文件中的 DATABASES = {....} 位，看看是否有效
