object.__init__() takes no parameters


I am trying to do a build of 0.7.49 in fedora rpm. I get the following error when running setup after the rpm build..

<mock-chroot>[root@apps-fp-oi-00000340 /]# askbot-setup

    super(SettingsTemplate, self).__init__(context=context, **kwargs)
TypeError: object.__init__() takes no parameters

The same works fine on epel-6 build.

is it a python2.6 vs 2.7 issue?

Do you still have this issue? what is your current dependencies libraries version? Could you do a pip freeze and update the question with the result?

It could be that you have previous version of askbot-setup script that is incompatible with the current version of Askbot. Make sure to remove all remnants of the previous version on your system, or better - install into a new virtual environment.

@Fitoria : sorry, was tied up, will get you a pip freeze. @Evgeny nope, am running it in a fresh chroot, no other installs.

In Askbot pystache dependency version is frozen at 0.3.1, you have a later version, this must be the problem. Please ask maintainer of the fedora rpm to fix this.

You might obtain more reproducible result when installing Askbot via virtualenv and the python methods ("pip install" or "python develop").

hi, the problem is pystache 0.3.1 is outdated and deprecated for latest fedora. Present stable pystache is 0.5.3-2 for fedora. I will see if I can patch askbot to work with the the newer pystache. Any specific reason to freeze the version?

No specific reason, if you make a patch that works I will merge it. Thank you.
