您似乎缺少从源代码构建包的一些先决条件。
You may install a binary package by installing 'psycopg2-binary' from PyPI.
If you want to install psycopg2 from source, please install the packages
required for the build and try again.
For further information please check the 'doc/src/install.rst' file (also at
<https://www.psycopg.org/docs/install.html>).

当 iam 运行命令时，它会出现此错误。 许多其他 python 包也会出现此错误。
还有其他方法可以下载 django-heroku。
【问题讨论】：
-
错误是针对
psycopg2，而不是django-heroku。按照消息的建议，尝试在您的要求中将psycopg2更改为psycopg2-binary。 -
最后一个
django-heroku版本是在 2018 年。您不需要安装它即可在 Heroku 上运行 Django 应用程序。我不会尝试安装它，除非你绝对确定你需要 - 我认为它不会解决你描述的问题 here。
