python - 如何在 Amazon Elastic Beanstalk 上安装 opencv-python

Question

我一直在本地开发一个 Python 应用程序，现在想将它部署到 Amazon Elastic Beanstalk，但是我遇到了以下错误:

Downloading/unpacking opencv-python==2.4.8.1 (from -r
/opt/python/ondeck/app/requirements.txt (line 12))  
Could not find any downloads that satisfy the requirement opencv-python==2.4.8.1
(from -r /opt/python/ondeck/app/requirements.txt (line 12))

Some externally hosted files were ignored (use --allow-external opencv-python to allow). 
Cleaning up... No distributions at all found for opencv-python==2.4.8.1 
(from -r /opt/python/ondeck/app/requirements.txt (line 12))

如果我使用 SSH 连接并键入 sudo pip install opencv-python，它会显示“正在下载/解压 opencv-python”一分钟左右，然后:

Could not find any downloads that satisfy the requirement opencv-python
Cleaning up...
No distributions at all found for opencv-python
Storing debug log for failure in /root/.pip/pip.log

我还尝试将“http://rpmfind.net/linux/fedora/linux/development/rawhide/x86_64/os/Packages/o/opencv-python-2.4.9-3.fc22.x86_64.rpm”添加到我的 requirements.txt 但失败如下:

Cleaning up...

我也试过“sudo yum install opencv-python”但失败如下:

Loaded plugins: priorities, update-motd, upgrade-helper

No package opencv-python available.
Error: Nothing to do

对于我的开发系统，我从 http://www.lfd.uci.edu/~gohlke/pythonlibs/#opencv 获得了安装程序.请问我怎样才能在 EB 上安装它？

如果没有办法安装这个确切的包，最好的选择是什么？

Answer 1

如果您能够考虑解决方法，这里有一些选项。

使用 AWS Elastic Beanstalk

• AWS EB 支持 Windows Server 2012 和 2008

  由于您的安装程序似乎是 Windows 可执行文件，您可以考虑在 Windows 上部署。 https://aws.amazon.com/net/

• 使用Docker打包Fedora平台运行在EB的AMI Linux主机上。

  Elastic Beanstalk 支持 Docker。
  http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/create_deploy_docker.html

  这是 python 上 opencv 的 Docker 构建文件示例。 https://registry.hub.docker.com/u/ibotdotout/python-opencv/

没有 AWS Elastic Beanstalk

• 其他 Linux 发行版

  如果您不是绝对需要 Elastic Beanstalk，那么运行 Fedora 怎么样？这些安装说明很简单。

  http://docs.opencv.org/trunk/doc/py_tutorials/py_setup/py_setup_in_fedora/py_setup_in_fedora.html(基本上是 yum install numpy opencv* )

  您可以在没有 Elastic Beanstalk 的情况下使用 EC2。
