python - 将 django 应用程序部署到 Elastic Beanstalk -requirements.txt 错误

Question

我在部署应用程序时遇到问题，特别是 requirements.txt 文件中的某些模块未得到满足。不太确定什么是最好的解决方案，因为该应用程序的本地版本可以工作。

正如您从日志中看到的，该错误出现了几次。有没有人遇到过这种情况，如果有的话有什么建议或解决方案吗？

Answer 1

在本地环境中运行pip freeze。这应该会给你一个依赖项列表。

例如，我将其放入 AWS 上的一个应用程序中

需求.txt

boto==2.38.0
Django==1.6.4
MySQL-python==1.2.5
argparse==1.3.0
dj-database-url==0.3.0
wsgiref==0.1.2
south==0.8.4
whoosh==2.7.0
django-haystack==2.4.0
django-elasticache==0.0.3
pylibmc==1.5.0
django-storages==1.1.8

而且您的 .config 文件`可能需要一些 yum 包，如下所示:

myapp.config

packages:
    yum:
        python27-devel: []
        libmemcached-devel: []
        libjpeg-turbo-devel: []
#01_syncdb:
...
