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 <https://www.psycopg.org/docs/install.html>). ---------------------------------------- Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-n6fpjkgb/psycopg2/这是由于安装psycopg2出现了问题，可以安装psycopg2-binary代替psycopg2
解决方法：
先安装django-heroku的依赖：
pip install django pip install whitenoise安装psycopg2-binary：
pip install psycopg2-binary最后无依赖安装django-heroku
pip install --no-dependencies django-heroku
