很难将 Python requirements.txt安装到 Elastic Beanstalk 上的 PHP 应用程序。
最初,我质疑将多个平台部署到 Elastic Beanstalk (PHP/Python)的能力。虽然这不可能开箱即用,但可以通过.ebextentions运行预安装命令
这导致创建.ebextentions/install_python_requirements.config
container_commands:
python_req:
command: 'pip install -r /var/app/ondeck/requirements.txt'
现在lxml
,问题是需求中的依赖关系,在部署过程中始终失败。奇怪的是,ssh
直接进入 EC2 实例然后运行pip install -r requirements.txt
完成没有问题。
为什么依赖项安装通过直接访问成功,但在使用和ssh
部署期间失败?eb deploy
install_python_requirements.config
/var/log/eb-activity.log中的失败
