在適用於Django部署的AWS Elasticbeanstalk上構建/安裝mod_wsgi時出錯

Question

我在嘗試部署Django應用時遇到以下錯誤。 我一直在http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/create-deploy-python-django.html的文檔中關注該教程。 我目前的直覺是因為pip試圖從源代碼而不是使用.whl來構建mod_wsgi，但這就是我的故障排除專業知識的程度。 我該如何解決？

排序。

apsx由httpd-devel軟件包提供。 然后使用eb ssh進行連接

yum list installed|grep httpd

查看與環境匹配的httpd-devel版本。 用安裝

sudo yum install httpd24-devel

接着

sudo /opt/python/run/venv/bin/pip install -r /opt/python/ondeck/app/requirements.txt

檢查它是否固定。 如果可行，則創建或編輯（本地）文件

.ebextensions/01_packages.config

或類似的內容作為部署的一部分添加：

packages:
    yum:
        httpd24-devel: []
