Question

我正在尝试将我的应用程序部署到heroku，但是执行 pip install django-heroku 后，出现错误。我在Mac上使用Django 2.2运行Python 3。

错误消息建议我安装 psycopg2-binary ，但是在安装后，我仍然看到相同的错误。谢谢您的帮助。

错误消息：

ERROR: Complete output from command python setup.py egg_info:
    ERROR: running egg_info
    creating pip-egg-info/psycopg2.egg-info
    writing pip-egg-info/psycopg2.egg-info/PKG-INFO
    writing dependency_links to pip-egg-info/psycopg2.egg-info/dependency_links.txt
    writing top-level names to pip-egg-info/psycopg2.egg-info/top_level.txt
    writing manifest file 'pip-egg-info/psycopg2.egg-info/SOURCES.txt'

    Error: pg_config executable not found.

    pg_config is required to build psycopg2 from source.  Please add the directory
    containing pg_config to the $PATH or specify the full executable path with the
    option:

        python setup.py build_ext --pg-config /path/to/pg_config build ...

    or with the pg_config option in 'setup.cfg'.

    If you prefer to avoid building psycopg2 from source, please install the PyPI
    'psycopg2-binary' package instead.

    For further information please check the 'doc/src/install.rst' file (also at
    <http://initd.org/psycopg/docs/install.html>).

Answer 1

安装此软件包对我来说是'libpqxx'（或从here引用的这个'libpq-dev'）！

注意：即时通讯使用的是Linux，因此您可能会有所不同

Answer 2

尝试：

sudo apt install libpq-dev

然后运行pip install django-heroku。应该可以。

django-heroku安装出现错误
