Cannot get it working

[Özer S.]

Tried you sample.md, but it just throws errors for me.

Steps I took:

virtualenv --python=`which python3` venv
source venv/bin/activate
pip install present

present sample.md

Throws following error:

Traceback (most recent call last):
  File "/Users/Zentrale/IT/tmp/present/venv/bin/present", line 5, in <module>
    from present.cli import cli
  File "/Users/Zentrale/IT/tmp/present/venv/lib/python3.6/site-packages/present/cli.py", line 7, in <module>
    from .markdown import Markdown
  File "/Users/Zentrale/IT/tmp/present/venv/lib/python3.6/site-packages/present/markdown.py", line 6, in <module>
    from dataclasses import dataclass
ModuleNotFoundError: No module named 'dataclasses'

When I install dataclasses manually with pip install dataclasses, the following error appears:

Traceback (most recent call last):
  File "/Users/Zentrale/IT/tmp/present/venv/lib/python3.6/site-packages/present/markdown.py", line 251, in parse
    Element = eval(element_name)
  File "<string>", line 1, in <module>
NameError: name 'BlockQuote' is not defined

During handling of the above exception, another exception occurred:

    sys.exit(cli())

ValueError: (Slide 4) BlockQuote is not supported

Any idea?

present only works with Python 3.7+. I think you might be on Python 3.6. Can you make a venv with Python3.7 and install present 0.5.1? That should do the trick 😄
