Problem description

• What were you trying to do?
  • What API call did it involve
  • What error was raised?

I tried the calling Zotero() and get this error:

~/miniconda/lib/python3.7/site-packages/pyzotero/zotero.py in <module>
    103 
    104 # Override feedparser's buggy isBase64 method until they fix it
--> 105 feedparser._FeedParserMixin._isBase64 = ib64_patched
    106 
    107 

AttributeError: module 'feedparser' has no attribute '_FeedParserMixin'

If possible, paste the full traceback in a code block below, and fill in the summary

Note that his error is not present if feedparser's version is < 6. It is likely a breaking change feedparser made in version 6.

Did you manually install Feedparser 6.0.1? Pyzotero's Feedparser version is pinned to 5.2.1 as the 6.x series isn't compatible with Python 2 or Python 3 versions below 3.6…

[moorepants]

It looks like the pyzotero conda feedstock is >=5.2.1 not ==5.2.1. Should it be >=5.2.1,<6 ?

[urschrei]

Yep, there's the problem.

Just pushed the v1.4.18 tag and release to PyPI to fix this. The bot should pick it up…

[moorepants]

Ok, the bot won't correct the dependencies in the meta.yaml file though. That still has to be done manually.

[urschrei]

OK, edited the bot PR to use feedparser <6.0.0, and merged.

[moorepants]

I made a comment on the PR. I think you want to set lower and upper bounds.

[urschrei]

Ah, wasn't sure whether I could do that. Sorry for jumping the gun! Opened a fresh PR at: https://github.com/conda-forge/pyzotero-feedstock/pull/18
