[Justin Hammond (justin-hammond)]

Would like to clarify that previous comment was in neutron's venv, not the tox venv. I am currently rebuilding the tox venv and will attempt to jump into that one.

[Justin Hammond (justin-hammond)]

After rebuilding the tox virtual environment the error went away. Sean, you may wish to try:

tox -r -e pep8

[Sean McCully (sean-mccully)]

Ok this is happening in the Jenkins builds though

[Sean McCully (sean-mccully)]

Clarification,

[Justin Hammond (justin-hammond)]

They appear to have magically started working again. Glitch in the matrix?

[Sean McCully (sean-mccully)]

Could be, but if there is a depends on six being less then 1.4.0 then 1.4.1 is the latest on pypi.

[Mark McClain (markmcclain)]

Closing this as this has resolved itself. This issue was mostly related to an upstream library.

[Yang Yu (yuyangbj)]

I will be out of the office starting 2013-09-05 and will not return until

I will be on my marriage leave from 9/5 to 9/15, for any urgent issue
please call me before 9/7.

For daily work, please ask my scrum master Zhu Zhu for help.
For glance issue, please ask glance SME Feilong Wang for help.
For defect report, there will be no report next week.
