python - 安装 psycopg2 失败 python 3.7

Question

我正在关注本教程 - https://medium.com/@qazi/how-to-deploy-a-django-app-to-heroku-in-2018-the-easy-way-48a528d97f9c

到目前为止我已经:

• 构建了我的 Django 应用程序并在本地运行 - 完美运行
• 写入Procfile内容网页:gunicorn project_name.wsgi
• 将 django_heroku 导入到设置

我需要安装 psycopg2，因此我运行了 pip install psycopg2

但出现错误

尝试运行 pip install psycopg2-binary，而不是 pip install psycopg2。
