python - 无法使用requirements.txt文件在Openshift python 3.3盒上安装最新的python包

Question

当我将源代码推送到 openshift python Cartridge 时，我收到此消息。

Could not find a version that satisfies the requirement requests==2.9.1

pip 似乎找不到 requirements.txt 文件中指定的包版本，但它是最新版本，并且可以在 pypi 包索引目录中找到。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

openshift 服务器响应是:

Answer 1

更新: submitting this problem to openshift bug reporting system之后他们解决了问题，现在一切都按预期进行。

正如“Vu Dinh”所说，问题的原因是:

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.

<小时/>

原答案:

我找不到任何解决方案来解决我所描述的问题，因此现在我在 deploy 操作 Hook 中使用两行命令来临时修复我的问题:

echo "installing dependencies..."
pip install -r "$OPENSHIFT_REPO_DIR"requirements.txt
