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

【问题标题】：Deploying django app to Elastic Beanstalk - requirements.txt error将 django 应用程序部署到 Elastic Beanstalk - requirements.txt 错误
【发布时间】：2016-07-01 17:42:17
【问题描述】：

我在部署应用程序时遇到问题，特别是 requirements.txt 文件中的某些模块不满意。不太确定最好的解决方案是什么，因为应用程序的本地版本可以工作。

从日志中可以看出，该错误出现了几次。有没有人遇到过这种情况，如果有，有什么建议或解决方案吗？

【解决方案1】：

在本地环境中运行 pip freeze。这应该会给你一个依赖列表。

例如，我在 AWS 上的一个应用程序中使用了这个

requirements.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

还有你的 .config 文件`可能需要一些 yum 包，例如：

myapp.config

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

你的答案可能在这里：Error while full update pip packages

【讨论】：

是的，我跑了pip freeze > requirements.txt，输出：Django==1.9.2 django-cors-headers==1.1.0 django-filter==0.13.0 djangorestframework==3.3.3 Markdown==2.6.5 MySQL-python==1.2.5
运行它并输出正确的依赖项，不知道为什么我在尝试部署时仍然遇到同样的错误......
和 vboxapi 甚至没有显示当我将 pip freeze 作为依赖项运行时。不知道为什么它在我尝试部署时显示
Collecting vboxapi==1.0 (from -r /opt/python/ondeck/app/requirements.txt (line 24))
为vboxapi 尝试了 pip 忽略相同的结果...奇怪

【解决方案2】：

好吧，我终于让它工作了，尽管它没有为我的原始问题提供答案。我基本上不得不从父 django 文件夹中压缩文件。一旦我这样做并重新上传它，包括requirements.txt，应用程序就成功部署了。
