@luckywarrior Thanks for your feedback!

The logs you provided show something wrong with pyparsing.

Can you show us how to reproduce the problem? The more info you can provide, the more quickly we can pin down and squash those bugs.

I open a new vm and reinstall the packages following your steps, a new problem occured when i tried to start a instance,it said as follows:(my environment:centos 6.8_x86_64 python2.6)

Traceback (most recent call last): File "bin/rurouni-cache.py", line 13, in run_twistd_plugin(file) File "/opt/Kenshin/kenshinEnv/lib/python2.6/site-packages/kenshin-0.3.1-py2.6-linux-x86_64.egg/rurouni/utils.py", line 11, in run_twistd_plugin from rurouni.conf import get_parser File "/opt/Kenshin/kenshinEnv/lib/python2.6/site-packages/kenshin-0.3.1-py2.6-linux-x86_64.egg/rurouni/conf.py", line 286 instances = {int(s[len(prefix):]) for s in parser.sections() ^ SyntaxError: invalid syntax

[luckywarrior]

problem solved ! changed this line: instances = {int(s[len(prefix):]) for s in parser.sections() to instances = [int(s[len(prefix):]) for s in parser.sections() if s.startswith(prefix)]

[zzl0]

They are different things, and instances = {int(s[len(prefix):]) for s in parser.sections() should not raise SyntaxError: invalid syntax. What's the version of your Python interpreter?

In [5]: a = [1, 1, 2, 3]

In [6]: {i for i in a}  # set
Out[6]: {1, 2, 3}

In [7]: [i for i in a]  # list
Out[7]: [1, 1, 2, 3]
