ImportError: No module named BeautifulSoup

Had this issue when you’ve been trying to run something like Funnelweb, and you hit an ImportError for BeautifulSoup?  You’re definitely not alone, because I just hit the same issue.  The answer is simple — just ensure that you don’t use BeautifulSoup 4 or above (this is still beta) — it uses a different namespace, specifically bs4. Thus, whilst you might have the BeautifulSoup egg satisfying your dependencies, any imports of this package are going to fail.

For me, I’m using buildout, so I just pinned my version of BeautifulSoup thusly:

[buildout]
...
versions = versions

[versions]
BeautifulSoup = 3.2 …

Python eggs and missing files (like ‘docs’)

This is pretty trivial (and trivial to fix), but I’m chronicling it for my knowledge as much as anyone else’s.  The issue is that a given Python egg is missing some form of files, most commonly the ‘docs’ directory in my experience, because the build wasn’t configured correctly.

An error occured when trying to install my.theme 1.5.0. Look above this message for any errors that were output by easy_install.

The solution is simple: just …

Plone: SiteManager leftovers; not the good kind

Leftovers are typically useful when they’re in your fridge at home. They mean you don’t have to mess around making lunch for the next day for work, and can just grab them, and walk right out the door. Now, leftovers in the zope.component SiteManager aren’t …

Plone/Zope, Python and collective.autoreload / plone.reload

Here’s an interesting error message I got stumped with for a good set of hours.  The issue started with me using collective.autoreload with Plone and it does the trick, mostly.  With any such ‘operation’ and live reloading of code for Python, you’ve got to expect that not everything will go according to plan.  Most things do, but one issue I found presented with this error message:

< ... huge traceback ...>
TypeError: super(type, obj): obj must be an instance or subtype of type

The issue arises for me (and you’ll probably see it elsewhere) when I go ahead …

Plone: Python Eggs And Development

Welcome to the new year! It’s the start of another journey around the sun and the beginning of work for me. Whilst I’m the only one actually working around here today, I thought I’d take the chance and update with some useful info:
