Python3.11+Amazon Linux2023部署Flask到Elastic Beanstalk遇安装错误

基本情况 #

能正常部署Elastic Beanstalk的示例应用，但自己的Flask应用部署失败。已按要求将主文件命名为application.py，并把Flask实例名改为application。

现有配置文件 #

.ebextensions/postgres.config #

最初配置：

packages:
    yum:
        mariadb-devel: []
        postgresql-devel: []

（已移除mariadb-devel，现在报错提示无法安装postgresql-devel）

.ebextensions/python.config #

commands:
  01_update_pip:
    command: "pip install --upgrade pip setuptools"

option_settings:
  aws:elasticbeanstalk:container:python:
    WSGIPath: application.py

项目目录结构 #

server（根目录）
├── .ebextensions
│   ├── postgres.config
│   └── python.config
├── application.py
└── requirements.txt
venv

部署日志关键报错 #

[INFO] Error occurred during build: Yum does not have postgresql-devel available for installation
[ERROR] An error occurred during execution of command [app-deploy] - [PreBuildEbExtension]
[WARN]could not build optimal types_hash, you should increase either types_hash_max_size: 1024 or types_hash_bucket_size: 64; ignoring types_hash_bucket_size

过往尝试 #

曾在Amazon Linux 2环境下完成部署，但出现网关错误，具体配置命令已记不清。优先想使用最新的Amazon Linux 2023，也接受其他更简单的部署方案。

附Amazon Linux 2下的参考配置（假设主文件为Application.py）：

commands:
  01_update_pip:
    command: "pip install --upgrade pip setuptools"

option_settings:
  aws:elasticbeanstalk:container:python:
    WSGIPath: Application:application
