Error when Building FEniCS from source

[Ray Zhang]

When I tried to build the FEniCS in Ubuntu 16.04 from source, I followed the step as follows as shown in the official site:

However, the cd ffc     && pip3 install . command give me an error like 

" Could not find a version that satisfies the requirement fenics-fiat<2018.2,>=2018.1.0.dev0 (from fenics-ffc===2018.1.0.dev0) (from versions: 2017.1.0.post1, 2017.2.0)

No matching distribution found for fenics-fiat<2018.2,>=2018.1.0.dev0 (from fenics-ffc===2018.1.0.dev0)"

However, "fenics_fiat-2018.1.0.dev0.egg-info" already exists in the path of the python (~/.local/lib/python3.5/site-packages).

 Could any friends help me figure out why it went wrong? I am using pip 8.1.1 in python 3.5.

When compile ffc using pip3 with option -v, I do find where went wrong since it tries to find the required numpy, fiat online, where numpy online is the suitable version but the fiat only is 2017.1.0 2017.2.0, which is not required. 

Here comes the problem, how to force the pip3 to find the pre-installed fiat in a designated directory?

I am getting the same error. I am installing fenics into a specified directory using --prefix and the ffc install cannot find the fiat distribution that is in the --prefix designated directory.

Do you know a way how to reproduce the problem? It works fine for me:

$ docker run -ti --rm python pip3 install --user fenics
[...]

This is not running it in a docker container but building from source on a cluster, in my case.

The command that I am using is as per their directions but with a different prefix on a Red Hat 7 system:

pip3 install --prefix=/packages/fenics/ .

I understand. Docker is used to demonstrate that Pip and FFC work. Do
you have a minimal working example?

[Jan Blechta]

That works for me:

docker run -ti --rm python bash -c '
mkdir -p $HOME/local && export PYTHONPATH=$HOME/local/lib/python3.6/site-packages:$PYTHONPATH
git clone https://bitbucket.org/fenics-project/fiat
git clone https://bitbucket.org/fenics-project/ufl
git clone https://bitbucket.org/fenics-project/dijitso
git clone https://bitbucket.org/fenics-project/ffc
cd fiat && pip3 install --prefix="$HOME/local" . && cd ../
cd ufl && pip3 install --prefix="$HOME/local" . && cd ../
cd dijitso && pip3 install --prefix="$HOME/local" . && cd ../
cd ffc && pip3 install --prefix="$HOME/local" . && cd ../
python3 -c"import ffc"
'

Just drop the first and the last line of the script above (and adjust
Python version in the site dir) to do it locally. Does that work?

I changed my model and removed the need for the --prefix and things are working much better. Now the install for dolfin is complaining about the eigen3 libraries. Trying to figure out where to get those.
