Problems with cx_Freeze and networkx

I am using the 64-bit python 2.7 on Windows. When I build an executable with cx_Freeze and then run it, I get an error window (, replace real names):

---------------------------
cx_Freeze: Python error in main script
---------------------------

stream = open(filename)
IOError: [Errno 2] No such file or directory: 'C:\\Users\\<dir_name>\\build\\exe.win-amd64-2.7\\library.zip\\lib2to3\\Grammar.txt'

---------------------------
OK
---------------------------


The file is not in the archive, but if I manually add it after the build, it is still not found. Looks like a path (backslashes?) issue.

Anybody knows how this could be fixed?

Also: Do you think this kind of problem would be better addressed with pyinstaller? The reason I opted for cx_Freeze is that the installation of pyinstaller itself seems very nontrivial, whereas cx_Freeze is a single whl.

Answer

I had the same issue using Py2exe.

I found out the issues is caused in NetworkX version 1.10

Rolling back to 1.9.1 worked for me:

pip uninstall networkx
pip install networkx==1.9.1
