无法使用 requirements.txt 文件在 Openshift python 3.3 卡带上安装最新的 python 软件包
Can't install latest python package on Openshift python 3.3 cartridge using requirements.txt file
我将源代码推送到 openshift python 卡带时收到此消息。
Could not find a version that satisfies the requirement requests==2.9.1
似乎pip 找不到requirements.txt 文件中指定的包版本，但它是最新版本并且在pypi 包索引目录中可用。如何强制 pip 使用 pypi 索引而不是它现在使用的索引？
如何重现此错误：
rhc app-create py33 python-3.3
cd py33
touch requirements.txt
echo requests==2.9.1 >> requirements.txt
git add .
git commit -a -m "requests2.9.1"
git push

更新： submitting this problem to openshift bug reporting system 他们解决了问题，现在一切正常。
问题的原因，正如"Vu Dinh"所说，是：
We do maintain a mirror for PyPi for our OpenShift system. So, sometimes, when a new package comes out in PyPi, our mirror will need to be resynced and during that time, the issue that you mentioned may occur.
他们必须重新同步镜像才能解决此问题：
the mirror has been resynced and I have tested it on my end. The issue has been resolved and you should be able to install the newest version requests. Please give it a try and let us know the result.
原答案：
我找不到我描述的问题的任何解决方案，所以现在我在 deploy 操作挂钩中使用两行命令作为我的问题的临时修复：
echo "installing dependencies..."
pip install -r "$OPENSHIFT_REPO_DIR"requirements.txt
