AWS Elastic Beanstalk中的mysqlclient安装错误

我正在AWS Elastic Beanstalk上部署django with mysql应用程序，因此需要

mysqlclient

库

mysqlclient

需要安装

python3-devel

和

mysql-devel

包，所以我有它的自定义配置文件

01_-packages.config

：

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

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

部署失败，日志文件

/var/log/cfn init.log

（在Beanstalk日志中提到）显示错误：

2020-05-31 02:17:41,834 [ERROR] -----------------------BUILD FAILED!------------------------

但是，我尝试通过

yum-install-mysql-devel

在我的Ec2实例上手动安装它，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

解决了我已经用

mariadb-devel

替换了

mysql-devel

，并且它成功地工作了，然后我能够安装

mysqlcient

库

我的新

01\u packages.config

：

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

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

我不知道它的根本原因，但我这么做是因为我注意到通过

yum-install-mysql-devel

手动安装

mysql-devel

实际上是在安装

mariadb-devel

下面是我的ec2实例发布详细信息。可能是因为新的AmazonLinuxRelease2

$ cat /etc/*-release*
NAME="Amazon Linux"
VERSION="2"
ID="amzn"
ID_LIKE="centos rhel fedora"
VERSION_ID="2"
PRETTY_NAME="Amazon Linux 2"
ANSI_COLOR="0;33"
CPE_NAME="cpe:2.3:o:amazon:amazon_linux:2"
HOME_URL="https://amazonlinux.com/"
Amazon Linux release 2 (Karoo)
cpe:2.3:o:amazon:amazon_linux:2

您的cfn-init.log日志中是否有更多内容显示如何调用yum？@danblack不幸的是，没有，它只是重复了相同的部分。我做了一些调查，事实上，旧的Amazon Linux AMI for Elastic Beanstalk似乎包括mysql，但Amazon Linux 2 AMI for Elastic Beanstalk没有。因此，正如Yasser所说，从旧平台升级到新平台时，似乎必须向配置文件中添加正确的包。我只需要mariadb devel。
