problems importing astropy.time in astropy 1.3

When I try to import astropy.time in astropy I get the following error

dlopen(/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/astropy/_erfa/_core.so, 2): Symbol not found: _eraEceq06

which seems to be a problem with _erfa/_core.so

does anyone else have this problem? Anyone know how to solve it? I tried uninstalling and re-installing both erfa and astropy but that didn’t help

I’m using mac OS 10.11.6, astropy version 1.3.0; python 2.7, macports 2.3.5

I downgraded to astropy 1.2 (the previous version) and do not have this problem

full import error is below

thanks

Mike

@mfacorcoran - That was a problem I introduced in Macports when I updated Astropy to 1.3, but forgot to update Erfa to 1.3 (10 days ago, see https://github.com/macports/macports-ports/pull/131). Apologies! It was fixed in https://github.com/macports/macports-ports/pull/133 six days ago.

Can you please try to update, the issue should be resolved now.

I always use these commands:

sudo port selfupdate
port outdated
sudo port -p upgrade outdated

Also – Python 3.6 is out and many packages are already available. If you don’t have to stick with Python 2.7, give it a try! 😃

sudo port install py36-astropy

[mfacorcoran]

Done!

cheers

Mike
