SUSE 11 SP2上安装FOLSOM，执行keystone提示如下错误，有大侠知道什么原因？
linux:~ # keystoneTraceback (most recent call last):

pkg_resources.DistributionNotFound: requests>=0.8.8,<1.0 --------------------编程问答-------------------- python-requests 版本依赖冲突吧。看看这个吧：
https://bugs.launchpad.net/ubuntu/+source/python-keystoneclient/+bug/1122146
--------------------编程问答-------------------- 确实，重新安装 python-requests 后，不再有这个提示了。不过另外有一个问题：
suse上自带的python版本是2.6.0，我将Python版本升级成2.7.3(官网下载后makeinstall的)，执行keystone总提示：Traceback (most recent call last):
File "/usr/bin/keystone", line 5, in <module>
from pkg_resources import load_entry_point
File "build/bdist.linux-x86_64/egg/pkg_resources.py", line 2603, in <module>

File "build/bdist.linux-x86_64/egg/pkg_resources.py", line 565, in resolve
pkg_resources.DistributionNotFound: python-keystoneclient==0.2.2
但实际上python-keystoneclient已经安装了
如果将Python版本切换会2.6，就没有这个提示了，但是由于keystone对Python的要求必须是2.6.8以上，否则后续的功能有问题，因此必须对python版本进行升级。 --------------------编程问答-------------------- 先升级Python 再安装，keystone，实在不行就源代码安装吧 --------------------编程问答-------------------- 怎么感觉包或者组件有问题那
