爲什麼在彈性豆莖中scipy的pip安裝？

Question

我正在將Django應用程序從Heroku遷移到Elastic Beanstalk。它在Heroku中正常工作。

我得到錯誤Your requirements.txt is invalid. Snapshot your logs for details.當我深入eb-activity.log我看到失敗似乎與atlas和scipy有關。我不明白爲什麼requirements.txt在aws上無效，但在heroku上有效。深入瞭解導致此錯誤的原因以及如何進行補救將不勝感激。

我eb-activity.log

注意：答案可能會稍微涉及到this question在用戶系統，它在Windows下編譯scipy問題。

我django.config在.ebextensions

option_settings: 
    aws:elasticbeanstalk:container:python: 
    WSGIPath: presto/wsgi.py 
packages: 

     yum: 
     postgresql93: [] 
     postgresql93-devel: [] 
     pkgconfig: [] 
     gcc-c++: [] 
     python34-devel: [] 

這可能是因爲我需要更多的依賴關係，以便正確編譯requirements.txt。

您需要安裝BLAS/LAPACK（以便您的系統上可以使用atlas和atlas-dev）。有關說明，請參閱this link，並嘗試將libblas-dev和liblapack-dev添加到配置文件中的軟件包yum列表中。
