No module named dolfin

Hi Juan,

I keep having problems with the installation of Fenics from Conda.

This is what I did:

conda create --name fenics27 python=2.7
source activate fenics27
conda install fenics --channel juanlu001

but then:

(fenics27)gamba@policefalo:~$ ipython
Python 2.7.6 (default, Jun 22 2015, 17:58:13) 
Type "copyright", "credits" or "license" for more information.

IPython 1.2.1 -- An enhanced Interactive Python.
?         -> Introduction and overview of IPython's features.
%quickref -> Quick reference.
help      -> Python's own help system.
object?   -> Details about 'object', use 'object??' for extra details.

In [1]: from dolfin import *
---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
<ipython-input-1-f9fe29351801> in <module>()
----> 1 from dolfin import *

ImportError: No module named dolfin

This is my environment:

Hello @porphyrius, what is happening is that the IPython that you are launching is not part of the conda installation and therefore is not seeing the FEniCS installation. Try again after conda install ipython, and if it still doesn't work please reopen the issue and paste the output of conda list.

Thanks a lot @Juanlu001, that was exactly what was happening, it's ok now!
