无法在AWS ElasticBeanstalk中部署Flask应用程序

Question

我正在AWS的Elastic Beanstalk环境中部署flask应用程序。它在我的本地应用程序中运行完全正常，但是当我将其上传到Beanstalk时，在日志文件中出现以下错误

[ERROR] An error occurred during execution of command [app-deploy] - [InstallDependency]. Stop running the command.

我的requirements.txt文件如下：

aniso8601==8.0.0
click==7.1.2
Flask==1.1.2
Flask-JWT==0.3.2
Flask-MySQLdb==0.2.0
Flask-RESTful==0.3.8

itsdangerous==1.1.0
Jinja2==2.11.2
MarkupSafe==1.1.1
mysqlclient==2.0.3
PyJWT==1.4.2
pytz==2020.1
six==1.15.0
SQLAlchemy==1.3.18
Werkzeug==1.0.1

甚至当我第一次在本地尝试使用pip安装-r requirements.txt时，我也遇到了同样的问题

但是，我使用以下步骤解决了它

1. $ brew install mysql
2. $ pip install mysqlclient

我假设在服务器上也需要做类似的事情。有人能帮我弄清楚如何在服务器上运行吗
