On a fresh conda environment I don't get these errors.
It seems astropy/utils/tests/test_state.py has been removed. Could it have been left behind from a previous install? are old files not expected to be cleaned out?

[astrofrog]

This file was indeed removed. How did you install the RC? (normally, I thought files that no longer exist should be removed by the installer)

[bsipocz]

I see the same errors on an ubuntu 14.04 after a standard pip install:
pip install --upgrade --pre --user --no-deps astropy

Previously installed version was 1.1.2

[astrofrog]

Interesting - I wonder if this is a pip bug? Presumably pip uninstall astropy then installing again works?

[bsipocz]

@astrofrog - you seem to be right with the pip issue. Trying to uninstall I get this Can't uninstall 'astropy'. No files were found to uninstall., however it still nicely imports and works.
Looking at the versions it seems that I'm using the system installed pip with an ancient version of 1.5.4.

[bsipocz]

So I can confirm that after (a pip upgrade and) an uninstall and install of astropy these failures go away.

[je-miralles]

I was originally on pip-8.1.2 with astropy-1.1.2 and did pip install astropy==1.2rc2 when I got the failures.

I tried uninstalling and re-installing :
pip uninstall astropy
pip install astropy==1.2rc1

Requirement already satisfied (use --upgrade to upgrade): astropy==1.2rc1 in /Users/juanemiliomiralles/anaconda/envs/ENV/lib/python3.5/site-packages

Requirement already satisfied (use --upgrade to upgrade): numpy>=1.7.0 in /Users/juanemiliomiralles/anaconda/envs/ENV/lib/python3.5/site-packages (from astropy==1.2rc1)

$ python -c "import astropy; astropy.test(remote_data=True)"
Traceback (most recent call last):
File "<string>", line 1, in <module>
AttributeError: module 'astropy' has no attribute 'test'

but after pip uninstall astropy==1.2rc1 && pip install astropy==1.2rc1 things are working properly with no failures.

[pllim]

Can we close this then?

[bsipocz]

I think yes, though tagging it as an upstream issue may be useful.
