Error after fresh install

• Install a new Pelican with Markdown
• Create a skeleton site with pelican-quickstart
• Add a 1 or 2 line content file as test.md
• Install this plugin with pip and set the PLUGINS var
  Generate the site with pelican .

Generates an error:
ERROR Could not process content/test.md log.py:96
LiquidTags.extendMarkdown() missing 1 required positional argument: 'md_globals'

I can reproduce the problem. Thanks for reporting!

Looks like liquid-tags expects md_globals argument, which was deprecated in Markdown package back in 2018. Markdown finally removed backwards-compatibility in release 3.4, released about two weeks ago.

We never use that variable, so fix is easy, but there's another issue under it. I will need more time to debug that.

In the meantime, you can downgrade markdown to last known working version:

pip install markdown==3.3.7

By the way, you don't need to include liquid_tags in PLUGINS var (unless you still use old-style pelican plugin). However, you should set LIQUID_TAGS variable for plugin to do anything interesting.

Thank you for the workaround!

@jaapnoordzij I have now merged the fix and released new version of a plugin. I can no longer reproduce the problem on fresh install.

You should now be able to update markdown package. Let us know if you encounter more issues.
