Issue when installing Astropy

[David Paz]

Hi all,

i just tried to install astropy locally for development. I am a newbie with astropy but not with python.

I started a clean virtual environment with virtualenv and then followed instructions until the activation of the development version when i try to check version i get AttributeError.

I will post here the dependencies of my venv along with the result of checking the version. Any idea will be welcome

Thanks in advance and cheers,

David

Just to be more accurate.

All Tests pass. I did install the test dependencies with: pip install -e '.[test]'. And everything ended as expected.

I think the question here is whether I am dealing with an specific installation issue regarding my dev environment or some other undocumented issue.

Thanks in advance,

Cheers,

David

That is weird. Do you have the stuff defined in pyproject.toml installed? https://github.com/astropy/astropy/blob/19cc80471739bcb67b7e8099246b391c355023ee/pyproject.toml#L1-L7

Hi, thanks for answering! No, i don't have all of them, I did install cython, because in the docs was asked to, just that one. 

After installing the test deps, what I have installed in my virtual environment is:

And you still have a problem with __version__ after rebuilding with the new stack? Do you see anything when you do "pip freeze  | grep setup"?

FWIW the dependencies in pyproject.toml should only get installed in a temporary build environment by pip so it shouldn’t matter if these are not visible with ‘pip freeze’

Yes, the same result. "pip freeze  | grep setup" gives me nothing.

thanks again,

David

[David Paz]

Now a dummy question please. Is it too much of a problem the version issue? I mean all test are passing actually.

[Pey Lian Lim]

As long as astropy is doing what you want, I guess it is okay. Except when you have to compare versions?

[David Paz]

I guess that will do as for now :)

Thanks!
