我在OpenShift上创建了我的Rails应用程序。它使用Python和从PIP安装的包。如何升级到更新的Python版本（目前是2.6）？

然后尝试安装更新的Python ......
user@debian:~$ rhc add-cartridge --app myappname python-3.3

There are no cartridges that match 'python-3.3'.
如果可以安装更新版本的Python，我该如何安装PIP？

没有名为python的磁带，因为当您尝试将磁带添加到现有应用时，它只会显示兼容的磁带。正如rhc cartridges命令所述：
Note: Web cartridges can only be added to *new* applications.
更新python版本的最佳方法是创建一个新应用并从旧应用中导入代码。
1）创建一个新应用
$ rhc app create py33 python-3.3
2）获取git url并将其作为远程添加到您的应用
$ cd old_python_app
$ git remote add py33 ssh://py33-giturl
$ git push py33 master -f
# Force push as the repo comes with default config files
至于pip，它预装了openshift。
$ rhc ssh py33
$ pip --version
pip 7.1.2 from /var/lib/openshift/.../python/virtenv/venv/lib/python3.3/site-packages (python 3.3)

我已将lib复制到OpenShift，将其包含在include路径中并使用py2.6执行它！问题解决了！
