Cannot import name 'LocationInfo' from 'astral' #58

Open matejmeglic opened 4 years ago

matejmeglic commented 4 years ago

Hello.

After installing astral with pip3 command (pip3 list returns --> astral 2.2 ), I cannot move forward from the code:

`#!/usr/bin/env python3

from astral import LocationInfo `

as I receive error: Traceback (most recent call last): File "astral.py", line 3, in <module> import astral File "/home/pi/python-scripts/astral.py", line 4, in <module> from astral import LocationInfo ImportError: cannot import name 'LocationInfo' from 'astral' (/home/pi/python-scripts/astral.py)

This is a noob question, but I don't have a solution? Thank you.

astral 2.2 does not have a file named astral.py, but the older versions did, so I'm going to assume that python is attempting the import from the old version.

I have the same problem, and I just installed astral today. The command I used was

pip install astral

which is the command I got from the astral v2.2 documentation.

Since I also see that astral.py was installed on my machine, there must be something wrong, either with the documentation or with pip.

Do you have any advice?

hudcap commented 4 years ago

What version do you see if you run pip show astral?

notuntoward commented 4 years ago

Here's the output of pip show astral:

Name: astral Version: 1.9.2 Summary: Calculations for the position of the sun and moon. Home-page: https://github.com/sffjunkie/astral Author: Simon Kennedy Author-email: sffjunkie+code@gmail.com License: Apache-2.0 Location: c:\users\scott\anaconda3\envs\keras\lib\site-packages Requires: pytz

Looks like whatever pip looks at is out of date? If it is, how do I get V2.2?

Thanks.

hudcap commented 4 years ago

Yup, that's why. Try pip install astral --upgrade

hudcap commented 4 years ago

It just occurred to me that if you installed it today and got the older version, you might be running an older version of python that is incompatible with the newer version of astral. Which python version are you running?

notuntoward commented 4 years ago

That fixed it. Thanks. Looks like it's the conda pvlib respository that's out of date (this is recommended by the pvlib docs, though).

Hello, I am having the same issue.

ImportError: cannot import name 'LocationInfo' from 'astral' (/Users/cooklaur/python/ve1/lib/python3.9/site-packages/astral.py)

I tried using the older version 1.10.1 and updating gw2pvo-docker as recommended on this thread: [https://github.com/markruys/gw2pvo/issues/37]. Neither fixed the isse.

I also updated astral to the latest version, recommded here, but this did not work.

This command, however, does work: from astral import Astral

I am using a virtual environment with python3.9. I am not using conda.

Any suggestions? Thank you.

lmcook88 commented 3 years ago

Ok, so I am not sure why, but uninstalling astral and then reinstalling the latest version again seemed to fix the issue. from astral import Astral no longer works, which I guess is an update for the newest version.
