ast_unparse - AttributeError: 'Name' object has no attribute 'update'

[kjcole]

Issue description

I recently installed Ubuntu 20.04 from scratch (reformatted the hard disk, etc.). I verified there were no files named pipenv* anywhere on the system -- including ~/.cache/.

$ pip install --user pipenv
$ pipenv update
...
  File "/home/kjcole/.local/lib/python3.8/site-packages/pipenv/vendor/requirementslib/models/setup_info.py", line 1139, in ast_unparse
    unparsed[func_name].update(unparse(keyword))
AttributeError: 'Name' object has no attribute 'update'

I've included the full traceback.

Expected result

I expecte pipenv to update

Actual result

It didn't update.

Steps to replicate

$ sudo updatedb
$ locate pipenv    # (returned no matching files)
$ pip install --user pipenv
$ pipenv update

I have encountered the same issue.

$ pipenv install
...
  File "/usr/local/Cellar/pipenv/2020.6.2/libexec/lib/python3.8/site-packages/pipenv/vendor/requirementslib/models/setup_info.py", line 1139, in ast_unparse
    unparsed[func_name].update(unparse(keyword))
AttributeError: 'Name' object has no attribute 'update'

Has this issue fixed? Or some way to walk around?

[elijahr]

I downgraded to pipenv==2018.11.26 as a workaround.

[the-moog]

Ubuntu 20.04LTS installed pipenv 2020.8.13 that had the same Attribute error issue with the svn [package] trachtmlnotification = {svn = "https://trac-hacks.org/svn/trachtmlnotificationplugin/0.12"}

I downgraded to pipenv==2018.11.26 and that resolved the issue.

I hope this info will help resolve the issue.

I also note that -v option is much more informative in the older release.

I can't reproduce either case with normal installation by pip. It may be a downstream packaging issue. You can try reporting it to Ubuntu.

[the-moog]

What python 2 are you using? This was using the system python2 2.7.18 and a virtualenv 2.7.17

[uranusjr]

I traced the code and it seems like this can happen if both keywords and kwargs attributes are present on item, but points to different values:

https://github.com/sarugaku/requirementslib/blob/1.5.13/src/requirementslib/models/setup_info.py#L1135-L1144

the first iteration would set unparsed[func_name] = val (where val is a Name object), and the second tries to call unparsed[func_name].update() (and fails since unparsed[func_name] is now a Name object). I am not sure if this is Debian-specific.

Fixed on v2021.11.5
