Can'；t使用requirements.txt文件在Openshift python 3.3盒式磁带上安装最新的python软件包

当我将源代码推送到openshift python盒带时，我得到了这个消息

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，可在pypi包索引目录中找到。我如何强制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服务器响应为：

更新：在他们解决问题后，现在一切正常

正如“Vu Dinh”所说，问题的原因是：

我们为OpenShift系统维护了一个PyPi镜像。因此，有时候，当PyPi中出现一个新包时，我们的镜像需要重新同步，在此期间，您提到的问题可能会发生

他们必须重新同步镜像以解决此问题：

镜子已经重新同步，我已经在我这边测试过了。问题已经解决，您应该能够安装最新版本的请求。请试一试，并告诉我们结果

---

原始答复：

对于我描述的问题，我找不到任何解决方案，因此现在我在

deploy

action hook中使用两行命令作为问题的临时修复：

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