I added:
sys.path.append(r"C:\Python27\Lib\site-packages\networkx")
to site.py in the ironpython folder and this is not enough to get
ironpython to see it, but it is enough to get cpython to see it without
any further changes.
Thanks for the subprocess suggestion, I'll change it as soon as I get
there. Do I simply copy that file and put it anywhere on the ironpython
path or do I have to replace an existing file?

It looks like networkx is a pure-Python package, so it should work.
What are you adding sys.path? I cloned the repo into the networkx
folder, which contains a networkx folder - sys.path should point to
the outer folder.
sys.path.append(r'C:\Users\<user>\Documents\Repositories\networkx')
Doing that, it complains that it can't find subprocess, which is a bug
in the alpha - I'm not sure it's fixed in B1, but it will be in B2. In
the meantime you can copy subprocess.py from
https://github.com/IronLanguages/main/blob/master/External.LCA_RESTRICTED/Languages/IronPython/27/Lib/subprocess.py
into the Lib folder for your IronPython installation.

Hello,
I am a very new user to Ironpython, so hopefully I am not missing anything
obvious. I read the FAQ and searched the Ironpython site and I couldn't
find a solution to the problem I was having.
I have installed both CPython 2.7 and Ironpython 2.7 (the alpha version) and
I am interested in using the networkx library (http://networkx.lanl.gov/)
under Ironpython.
I installed networkx here:
C:\Python27\Lib\site-packages\networkx
using the cpython interpreter, the installation worked fine:
import networkx as nx
G=nx.Graph()
G
<networkx.classes.graph.Graph object at 0x02C04250>
if I try to use the ironpython interpreter:
I get a:
File "<stdin>", line 1, in<module>
ImportError: No module named networkx
I tried manually adding the site.py file, to add networkx manually to the
path, but even after adding it (and checking that it shows up in
system.path) ironpython still doesn't see it.
Anyone have useful advice here?
Thank you very much,
Federico
