我正在尝试使用ElasticBeanStalk放置基于Django的WebApp，但是在部署过程中，我得到了一些错误，请检查日志文件。我搜索了日志文件但无法理解错误，任何人都可以帮助我了解发生了什么？

我正在使用Pycharm进行开发，但使用pip freeze命令来生成这些要求。
Update1：我删除了一些要求并成功部署，但在尝试从链接访问webapp时遇到Server 500错误。
答案 0 :(得分：0)
Elastic Beanstalk正在尝试逐个安装您的requirements.txt项目，但它会在＆＃34; egg_info＆＃34;处停止。这是错误：
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-n5etdtzo/matplotlib/
我猜你没有为本地开发使用虚拟环境。这就是为什么你在requirements.txt中看到所有不必要的项目的原因：
您有两种选择：
尝试在您的实例上手动安装（或删除）那些发生错误的操作（在每次部署失败后逐个安装）。为此，您必须直接连接到您的EC2，然后pip install或sudo pip install。您可能需要重复几次此过程。
（无法尽快切换到此方法）创建一个简单的virtualenv并选择真正需要的要求，然后再次尝试部署。
创建新环境：
cd my_app
virtualenv .
激活env：
source bin/activate
创建新的requirement.txt
pip freeze > requirements.txt
只添加NECESSARY项目，并完成！
