mysqlclient在AWS Elastic Beanstalk中安装错误

Question

我在AWS的Elastic Beanstalk上部署了一个带mysql的django应用，所以，我想在AWS上部署一个带mysql的django应用。mysqlclient 库是需要的。mysqlclient 需要 python3-devel 和 mysql-devel 包来安装，所以我为它准备了自定义配置文件。01_packages.config:

packages: 
  yum:
    python3-devel: []
    mysql-devel: []

部署失败，日志文件 /var/log/cfn-init.log (Beanstalk日志中提到的)显示错误。

然而，我试图通过以下方式手动安装到我的Ec2实例上 yum install mysql-devel 并且安装成功。

我的python版本是3.7，我的 requirements.txt 文件内容是。

asgiref==3.2.7
Django==3.0.5
django-cors-headers==3.2.1
django-dotenv==1.4.2
django-social-share==1.4.0
mysqlclient==1.4.6
numpy==1.18.4
pandas==1.0.3
Pillow==7.1.1
python-dateutil==2.8.1
pytz==2019.3
six==1.14.0
sqlparse==0.3.1
xlrd==1.2.0

解决了! 我已经替换了 mysql-devel 与 mariadb-devel 并成功运行，然后我就可以安装 mysqlcient 图书馆。

我的新 01_packages.config:

packages: 
  yum:
    python3-devel: []
    mariadb-devel: []

我不知道其根本原因，但我这样做是因为我注意到手动安装的 mysql-devel 通过 yum install mysql-devel 实际上是在安装 mariadb-devel !

这是我的ec2实例发布详情。也许是因为新的Amazon Linux Release 2。
