convirt安装过程中报错

[????LTX]

系统：centos6.5
内核版本：2.6.32-431.el6.x86_64

[root@convirt ~]# ./convirt-install/install/cms/scripts/setup_tg2
Processing dependencies for tg.devtools
error: PEAK-Rules 0.5a1.dev-r2582 is installed but PEAK-Rules==dev,>=0.5a1.dev-r2562 is required by set(['prioritized-methods'])
ERROR: installing TG2 (2.0.3).
ERROR: Failed creating Turbogears2 environment.

还是这个错误，在网上找了好多，方法也都试过了，升级python什么的都没有用，不知道哪位大神已经解决这个问题，或者有谁安装成功了但没出现这个问题，请指教。
