问题描述
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要求我安装了psycopg2，但我不知道如何运行它。
I'm deploying my first app(Flask) to EB and am hitting a snag. Using PostgreSQL requires that I get psycopg2 installed but I can't figure out how to get it running.
我在这篇文章中看到了（）以及此信息（），我需要使用以下代码添加文件名 .elasticbeanstalk / 01_packages.config ：
I saw in this post (Psycopg2 on Amazon Elastic Beanstalk) as well as this post(https://realpython.com/blog/python/deploying-a-django-app-to-aws-elastic-beanstalk/) that I need to add a file name .elasticbeanstalk/01_packages.config with the following code:
packages:
yum:
postgresql-devel: []
我尝试了 postgresql93-devel：[] 的其他变体，但还是没有运气。以下是我的错误日志。
I've tried different variations with postgresql93-devel: [] and still no luck. Attached below are my error logs.

似乎很明显我需要安装psycopg2但我不确定我还可以采取什么其他步骤来完成这项工作。
It seems pretty clear that I need to get psycopg2 installed but I'm not sure what other steps I can take to make this work.
推荐答案
我解决了它，您需要打开您先安装EC2实例，然后像这样安装
I solved it, you need to open you EC2 instance first, then install like this
sudo yum install postgresql-devel
然后部署您的EB
