AttributeError: 'module' object has no attribute 'Locale'

[RichardBradley]

I have the following error when I run make test at the current HEAD version (c553375) of this project on an Amazon Linux 2 VM in a python venv:

$ make test
...
running build_ext
Traceback (most recent call last):

    result['icu'] = icu = pyicu.Locale(locale)
AttributeError: 'module' object has no attribute 'Locale'
make: *** [test] Error 1

I believe that the "import icu as pyicu" line here is importing itself. I don't understand why this affects me and not other users, or how this is meant to work.

Here is a full repro:

# make test

The following patch fixes this issue for me:

I encountered this when trying to run certbot.

Can anyone explain what has gone wrong here? Is this a bug in parsedatetime or in Amazon Linux 2?

Is there a better workaround than applying the above patch to my site-packages?

Thanks,

Rich

Hi Richard, see #247 (and #245, #246, and #248).

Thanks!

Hopefully your PR will get merged and released soon. I think there are lots of people still using Python 2, often without explicitly choosing to do so but via provided systems like Amazon Linux 2.
