Unable to install uszipcode

[djl]

I have been trying to install the uszipcode package which is available on PyPI. It looks like a pure python package, and seems to install without problems with pip. Nonetheless, after trying from uszipcode import SearchEngine I get the error message "ImportError: cannot import name 'SearchEngine'" despite the fact that the class SearchEngine is clearly visible in the site package module. I feel like I'm missing something basic about installing and using python modules. Can anyone explain where I've gone wrong?

[djl]

import uszipcode doesn't produce an error message. Referring to it from the command line produces: ```

uszipcode
<module 'uszipcode' from '/private/var/mobile/Containers/Shared/AppGroup/33F42B57-E4B9-4767-9D62-5D195D377333/Pythonista3/Documents/site-packages-3/uszipcode/init.py'>```

Trying to import the search engine brings this response:

>>> from uszipcode import SearchEngine
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: cannot import name 'SearchEngine'```

Have you tried

from uszipcode.search import SearchEngine

Or import uszipcode.search?

Also, did sqlalchemy install (is it in site-packages-3)? I noticed that is a dependency, which has some non pure python.

[JonB]

@djl I noticed that in init, they try/except the real import errors that are occuring:

try:
    from .search import (
        SearchEngine, SimpleZipcode, Zipcode, ZipcodeType, SORT_BY_DIST,
    )
except Exception as e:  # pragma: no cover
    print(e)

So, try
import uszipcode.search

And report back on the exception. My guess is sqlalchemy.

SQLAlchemy installed, sort of...

But after that -- same failure to import SearchEngine

And after installing pathlib_mate:

>>> import uszipcode.search
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/private/var/mobile/Containers/Shared/AppGroup/33F42B57-E4B9-4767-9D62-5D195D377333/Pythonista3/Documents/site-packages-3/uszipcode/search.py", line 16, in <module>

    from pathlib_mate import Path
ImportError: cannot import name 'Path'

This is not for the faint of heart

[JonB]

That jerk seems to love hiding exceptions in all his projects ;).

Try
import pathlib_mate.pathlib2

And see what squawks next

[djl]

@JonB

import pathlib_mate.pathlib2
Traceback (most recent call last):
File "<string>", line 1, in <module>

import autopep8
ModuleNotFoundError: No module named 'autopep8'

So I installed autopep8 and tried again:

import pathlib_mate.pathlib2

No exceptions there. But going back to the beginning, still can't import 'Path'

[JonB]

How about

from pathlib_mate.pathlib2 import Path

You might need to force quit pythonista and try again. If pathlib2 imported successfully, it should have Path.

@JonB

After rebooting the iPad, that actually worked!! Amazing! Although I notice one of my other well functioning scripts stopped working. Is that because all of the newly installed modules somehow mess up previously working ones?

[djl]

@JonB
Now everything is hunky-dory. Thanks for your help, Jon. I would have given up long ago.

[JonB]

Could be... You'd have to look at the tracebacks to see what is failing. Check site-packages-3 and make sure you don't have any modules elsewhere named the same as one of the ones in the top level site-packages-3.
