为什么弹力豆柄的枕骨安装失败？

Question

我正在将Django应用程序从Heroku迁移到ElasticBean秸秆。它在Heroku工作得很好。

当我深入到Your requirements.txt is invalid. Snapshot your logs for details.中时，我会得到错误eb-activity.log，我看到失败似乎与atlas和scipy有关。我不明白为什么requirements.txt在aws上无效，在heroku上有效。对造成这一错误的原因以及如何补救的洞察力将是非常感谢的。

注意:答案可能与这个问题有关，其中用户在Windows中编译scipy时遇到了问题。

我的django.config in .ebextensions

为了正确编译requirements.txt，我可能需要额外的依赖关系。

您需要安装BLAS/LAPACK (以便atlas和atlas-dev在您的系统上可用)。有关说明，请参见此链接，并尝试将libblas-dev和liblapack-dev添加到配置文件中的包的yum列表中。
