我正在将Django应用程序从Heroku迁移到Elastic Beanstalk。它在Heroku中运行良好。
我收到错误Your requirements.txt is invalid. Snapshot your logs for details.当我深入eb-activity.log时，我发现失败似乎与atlas和scipy有关。我不明白为什么requirements.txt在aws上无效，但在heroku上有效。深入了解导致此错误的原因以及如何解决问题将非常感激。

注意：答案可能与用户在Windows中编译scipy时出现问题的this question略有关系。
django.config中的.ebextensions
option_settings:
aws:elasticbeanstalk:container:python:
WSGIPath: presto/wsgi.py
packages:
yum:
postgresql93: []
postgresql93-devel: []
pkgconfig: []
gcc-c++: []
python34-devel: []
我可能需要额外的依赖项才能正确编译requirements.txt。

您需要安装BLAS / LAPACK（以便系统上可以使用atlas和atlas-dev）。有关说明，请参阅this link，然后尝试将libblas-dev和liblapack-dev添加到配置文件中的yum列表中。
