'DiGraph' object has no attribute 'node'

[theRealSuperMario]

Hi,

I love the idea of this project, however, it does not work for me. See output below.

Is there anything I can do to help fix this?

pip install networkx==1.11

In python 3 it is. Nodes not node I think. Read back over the issues, it is not a new problem.

@alexpazolinid @theRealSuperMario did you try pip install networkx==1.11 as mentioned by @RobBW ? For me this worked. If it worked for you too, please close the issue. :)

[DQuanR2]

It also got fixed for me with the "pip install networkx==1.11"

[ipesanz]

It worked for me in Windows 10, Python3.8 with network install After that.... the output is a long list of str and a file generated :)

pip install networkx==1.11

thank you, For me this worked, it solve my problem

I would suggest just go to that source file (D:\Python\Python39\lib\site-packages\networkx\algorithms\dag.py), remove the import statement, and replace the gcd occurrences with math.gcd

[DeeMW]

the fractions.py is actually using math.gcd itself.

Why doesn't this work with the latest networkx? (2.6.2)

Not sure what happens, but 'DiGraph' object has no attribute 'node' in networkx==1.11 as well:

I am going to submit a PR.

I'm having the same issue with python 3.8 and networkx==1.11 has solved the problem.
