py27-sympy build fails: AttributeError: 'module' object has no attribute 'sqrtrem'

[istlota@…]

Today, weeks after the last time I ran code which imports sympy, I ran it again and the code failed with a runtime error indicating some problem while importing sympy. This is code that worked fine a few weeks ago when python27 was specifically v2.7.3 . This is the first time I have done anything with sympy since I upgraded python27 to v2.7.5 .

I port uninstalled py27-sympy and attempted to reinstall it. That now fails during building with an error in the main.log which I have zipped and attached.

The error in the log is:

AttributeError: 'module' object has no attribute 'sqrtrem'

This is described here: ​http://code.google.com/p/sympy/issues/detail?id=3592

It suggests that gmpy version 2 is too new and that gmpy 1 is required (or was until this was fixed in sympy earlier this year).

MacPorts has separate ports for these: py-gmpy and py-gmpy2. py-simpy doesn't declare a dependency on either of them. Perhaps it is used opportunistically, and you did not have py27-gmpy2 installed last time you successfully installed py27-sympy, but now you do?

Per ryandesign's response:

sudo port uninstall py27-gmpy2 sudo port install py27-gmpy sudo port install py27-sympy

py27-gmpy and py27-sympy installed without errors, after which my code which imports sympy now works again. Thanks as usual for a prompt and effective response!
