Hello,
If I understood correctly the error message changed when you manually
installed dolfin. Could you please try and install ffc and the rest of
the requirements too? In principle conda should resolve the dependencies
itself but perhaps something is not working well.
conda install |boost eigen3 petsc petsc4py instant ufl fiat
ffc|--channel juanlu001
Please post also the output of 'conda list' with fenics27 activated.
Regards,
Juan Luis Cano

Dear Juan Luis Cano,
Thanks a lot for your kind reply.
The following is the result from the command "which python" after
'source activate fenics27'. I tried to install with the command you
recommend "conda install dolfin --channel juanlu001", but it still
does not work.
~/envs/fenics27/bin/python
The following is the result I got with the command "conda info -a"

When running the demo, the error is
"DOLFIN runtime dependency is not met.
Install the following python module: 'ffc'
and make sure its location is listed in PYTHONPATH."
I think the reason may probably be the PYTHONPATH.

Hello,
Could you post the result of 'which python' after you do 'source
activate fenics27'? Perhaps doing
conda install dolfin --channel juanlu001
works instead. In any case, please post the result of 'conda info
-a' too. Did you download the demo from source or do you have it
installed in your path already?

Dear All,
I installed fenics with conda on our university cluster with
the following command:
"conda create --name fenics27 python=2.7
source activate fenics27
conda install fenics --channel juanlu001"
The process went well and I have a folder name "envs"
containing "fenics27" in my home folder. When I tried to run
some demo, e,g, "demo_cahn-hilliard.py", I got the error:
"Traceback (most recent call last):
File "demo_cahn-hilliard.py", line 27, in <module>
from dolfin import *
ImportError: No module named dolfin"
I think I need some command to add the path library of fenics
to my system, but I did not how to do that. Could anyone help
me on this?
I also tried the command "ldd
<INSTALL_PATH>/anaconda/envs/fenics27/lib/python2.7/site-packages/dolfin/cpp/_common.so"
but it still does not work.
Thanks a lot.
Best,
Teng
