[鄭暐勳]

Can someone tell me about this error?

I've already tried remove and reinstall gi-cairo, gi, and pygraphviz many times, but it still not work.

Please help me about this!!!

It looks like you are on an Ubuntu or Debian system. Can you please try
this for completeness, and try bake again?

apt-get install gir1.2-goocanvas-2.0 python-gi python-gi-cairo
python-pygraphviz python3-gi python3-gi-cairo python3-pygraphviz
gir1.2-gtk-3.0 ipython ipython3

HI 

i have the same exact issue could you tell me how did you solve the problem 

I can't find the solution anywhere.

I appreciate your time

[鄭東濬]

Hi,

I didn't solve that problem in the end, I'm not sure whether it is the problem of b+'s core or not.

I found other user's docker file on GitHub, they build in ubuntu14.0, and it could work, maybe you can search and try it.

I wish this information can help you to do your project.
