sparse "invalid syntax" error. Python 3.4 / virtualenv

[marianov]

In OSX, installed python3 (3.4), created a virtualenv, installed sreamparse, and whenever it runs it show "invalid syntax" error.

When installing streamparse there where similar errors:

The FAQ says it should work with Python > 3.3

Don't know if this is a user error or a bug.

Duplicate of #76 and #170. You just need to install the Python 3 compatible fork of fabric in our requirements.txt.

Apologies for opening an old issue, but having run pip install fabric3, I get the following error when trying to run sparse quickstart word count

  File "/Users/george/sites/venv/bin/sparse", line 5, in <module>
    from pkg_resources import load_entry_point
  File "/Users/george/sites/venv/lib/python3.5/site-packages/pkg_resources.py", line 2716, in <module>
    working_set.require(__requires__)
  File "/Users/george/sites/venv/lib/python3.5/site-packages/pkg_resources.py", line 685, in require
    needed = self.resolve(parse_requirements(requirements))
  File "/Users/george/sites/venv/lib/python3.5/site-packages/pkg_resources.py", line 588, in resolve
    raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: fabric

It would seem that sparse is looking for fabric, while Fabric3 installs as fabric3.....?

@Erve1879, yeah, that is unfortunately an issue in the version of streamparse you're using. Both of the 3.0 developer preview releases do not have this issue anymore.

[dan-blanchard]

You can see more info about the new releases here.

Thanks for the quick response @dan-blanchard - since this is my first stab-at-streamparse, I'll start with the dev release.
