Question

我一直在本地开发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))

如果我用SSH连接并输入sudo pip install opencv-python它会说“下载/解压缩opencv-python”一分钟左右，那么：

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

我也尝试在我的requirements.txt中添加“http://rpmfind.net/linux/fedora/linux/development/rawhide/x86_64/os/Packages/o/opencv-python-2.4.9-3.fc22.x86_64.rpm”，但失败如下：

Cleaning up...

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

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。我怎么能把它安装在EB上呢？

如果没有办法安装这个确切的包裹，请问最好的选择是什么？

Answer 1

如果您能够考虑解决方法，可以使用以下选项。

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，因此您可以考虑在Windows上进行部署。 https://aws.amazon.com/net/
使用Docker打包Fedora平台，以便在EB的AMI Linux主机上运行。

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

以下是python上opencv的Docker构建文件的示例。 https://registry.hub.docker.com/u/ibotdotout/python-opencv/

没有AWS Elastic Beanstalk

其他Linux发行版

如果您不完全需要Elastic Beanstalk，那么运行Fedora会怎么样？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。

Answer 2

目前简单的解决方法是安装pip 1.2.1，它不需要SSL：

curl -O https://pypi.python.org/packages/source/p/pip/pip-1.2.1.tar.gz
tar xvfz pip-1.2.1.tar.gz
cd pip-1.2.1
python setup.py install

也许这可以帮到你

Answer 3

我在Amazon EC2上运行OpenCV，在Ubuntu 14.04的专用实例上运行Python。我必须从源代码安装和编译才能获得可靠的python堆栈。
