我正在设置要在Heroku上部署的新Django项目，但是当我遵循Django Heroku部署指南时，在“ pip install django-heroku”期间遇到错误。
我正在运行：
操作系统：MacOS Mojave 10.14.6
virtualenv：python3
pip冻结输出：
(env) MacBook-Pro:testing_django sudoxx2$ pip freeze
dj-database-url==0.5.0
Django==2.2.3
gunicorn==19.9.0
psycopg2-binary==2.8.3
pytz==2019.1
sqlparse==0.3.0
whitenoise==4.1.3
这是执行pip install django-heroku命令后的错误输出：
(env) MacBook-Pro:testing_django sudoxx2$ pip install psycopg2-binary
