                  问题描述

                  我正在 AWS Elastic Beanstalk 上部署带有 mysql 应用程序的 django,因此需要 mysqlclient 库.mysqlclient 需要安装 python3-develmysql-devel 包,所以我有它的自定义配置文件 01_packages.config:

                  I am deploying a django with mysql app on AWS Elastic Beanstalk, so mysqlclient library is needed. mysqlclient needs python3-devel and mysql-devel package to be installed, so I have the custom config file for it 01_packages.config:

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

                  Deployment fails and the log file /var/log/cfn-init.log (mentioned in Beanstalk logs) shows the error:

                  但是,我尝试通过 yum install mysql-devel 在我的 Ec2 实例上手动安装它并成功安装.

                  However, I tried to install it manually on my Ec2 instance through yum install mysql-devel and it is installed successfully.

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

                  My python version is 3.7 and my requirements.txt file content is:

                  推荐答案

                  已解决! 我已经将 mysql-devel 替换为 mariadb-devel它运行成功,然后我就可以安装 mysqlcient 库.

                  Solved! I have replaced mysql-devel with mariadb-devel and it worked successfully, then I was able to install mysqlcient library.

                  我的新01_packages.config:

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

                  我不知道它的根本原因,但我这样做是因为我注意到通过 yum install mysql-devel 手动安装 mysql-devel 是实际安装mariadb-devel !

                  I don't know the root cause of it, but I did so as I noticed that the manual installation of mysql-devel through yum install mysql-devel is actually installing mariadb-devel !

                  这是我的 ec2 实例发布详细信息.也许是因为新的 Amazon Linux Release 2.

                  Here is my ec2 instance release details. Maybe it is because of the new Amazon Linux Release 2.

                  $ 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
