Googled my way around this issue, but didn't find any solutions. I'm running Python 3.3 with Eclipse and PyDev plugin, and when I run any Python project, I get the following message:
/Library/Frameworks/Python.framework/Versions/3.3/lib/python3.3/site-packages/update_checker.py:37: ResourceWarning: unclosed file <_io.BufferedReader name='/var/folders/x4/st67yr0x6qg7znh7sdfr94kh0000gn/T/update_checker_cache.pkl'>
permacache = pickle.load(open(filename, 'rb'))
I'm kind of new to Python, and I have no idea what this means. I wanted to ask before deleting this to make sure it's safe to delete. What does this even mean? I get there's an open file... but why is Python complaining to me? I'm using the PRAW library, if that makes any difference.
Update: My code is here on sourceforge, but it doens't reliably come up with the error (tried on 2 different computers). Once the error comes up, it never goes away.
