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

似乎pip无法找到requirements.txt文件中指定的软件包版本，但它是最新版本，并且可以在pypi软件包索引目录中找到。我如何强制pip使用pypi索引而不是它现在正在使用的索引？

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：在submitting this problem to openshift bug reporting system之后他们解决了问题，现在一切正常。

问题的原因，如＆＃34; Vu Dinh＆＃34;那里说，是：

我们为OpenShift系统维护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启动，在此期间，您提到的问题可能会发生。

他们不得不重新同步镜像来解决这个问题：

镜子已经重新安装，我已经测试了它。问题已解决，您应该能够安装最新版本的请求。请试一试，让我们知道结果。

原始答案：

我找不到我所描述的问题的任何解决方案，所以现在我在deploy动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

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