我正在将我的第一个应用程序(Flask)部署到EB,并且遇到了麻烦.使用PostgreSQL需要我安装psycopg2,但我无法弄清楚如何让它运行.
我在这篇文章(Psycopg2 on Amazon Elastic Beanstalk)以及这篇文章(https://realpython.com/blog/python/deploying-a-django-app-to-aws-elastic-beanstalk/)中看到,我需要使用以下代码添加文件名.elasticbeanstalk / 01_packages.config：
packages:
yum:
postgresql-devel: []
我用postgresql93-devel尝试了不同的变化：[]但仍然没有运气.下面附有我的错误日志.

似乎很清楚我需要安装psycopg2,但我不确定我可以采取哪些其他步骤来使其工作.
解决方法
我解决了,你需要先打开你的EC2实例,然后像这样安装
sudo yum install postgresql-devel
然后部署您的EB
