如何运行reddit.com网站的克隆。 Reddit.com源代码在Ubuntu 9.10上实现时出现错误（karmic）

Question

I am implementing the reddit.com source code on ubuntu karmic 9.10.

I have followed all the steps and in one step where i am using paster command it throws an error. $paster shell example.ini

File "/usr/local/lib/python2.6/dist-packages/Pylons-0.9.6.2- py2.6.egg/pylons/middleware.py", line 11, in from webhelpers.rails.asset_tag import javascript_path ImportError: No module named rails.asset_tag

I have checked for the version for webhelpers, its the latest installed.

Could anybody tell me that by installing another version of webhelpers will solve this problem?

Or Shall i modify the code?

Its a reddit.com source code written in python, using pylons framework.

I am unable to decide that whether by installing any previous version of webhelpers helps or shall i modify the code.

If there is anybody who have implemented the reddit.com website please help me or suggest me the best way.

thanks SIA

You need to ensure that all the libraries needed by your Reddit clone are on Python's module search path . There are a lot of different ways to accomplish this. The easiest is probably to just use setuptools ' easy_install command to install them (though this is my own personal least favorite way to install Python libraries, and also opens new cans of worms in the form of "Why not use distribute or pip instead?").

The next easiest way is probably to download and unpack the source code for the libraries you need and either a) setup.py install them or b) add their directories to your $PYTHONPATH or sys.path variables.

The documentation linked above has more info on how to control the module search path.
