Installation routine
LLTommy opened this issue · 6 comments
Hey,
I stumbled across your project and I think it is interesting, so I wanted to try it but unfortunately it fails during installation. After cloning I initialise the virtual environment and start to install the requirements, but then it fails. It complains about 'error: Error locating graphviz.' and might be related to this. I am on a Mac by the way. I don't have the time to really investigate this at the moment though but I thought I let you know so you are aware of this.
yepp, i noticed this recently as well. Seems that on some systems some of the packages behave differently if installed together from a single pip install -r requirements.txt. Simply re-running the line several times worked for me ^^
I'll see if i find a more reasonable workaround for this
Hi unfortunately I can not confirm this. It seems to fail always at the same point at the moment for me at least. "Failed building wheel for pygraphviz .... error: Error locating graphviz." I just tried to run it like 10 times, does no help. So.... I am up for a workaround. ;)
could you try looping the following a couple of times?
while read line ; do pip install "$line" ; done < requirements.txt
Nope, that did not change anything. It still fails at the same position:
The first error is still
cc -fno-strict-aliasing -fno-common -dynamic -arch x86_64 -arch i386 -g -Os -pipe -fno-common -fno-strict-aliasing -fwrapv -DENABLE_DTRACE -DMACOSX -DNDEBUG -Wall -Wstrict-prototypes -Wshorten-64-to-32 -DNDEBUG -g -fwrapv -Os -Wall -Wstrict-prototypes -DENABLE_DTRACE -arch x86_64 -arch i386 -pipe -I/System/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7 -c pygraphviz/graphviz_wrap.c -o build/temp.macosx-10.10-intel-2.7/pygraphviz/graphviz_wrap.o
pygraphviz/graphviz_wrap.c:2954:10: fatal error: 'graphviz/cgraph.h' file not found

Failed building wheel for pygraphviz
It follows with:
Your Graphviz installation could not be found. 1) You don't have Graphviz installed:
Install Graphviz (http://graphviz.org) 2) Your Graphviz package might incomplete.
Install the binary development subpackage (e.g. libgraphviz-dev or similar.)
So yes, I know there is a problem with graphviz. I could head over there and try to install it manually, however, I feel like the point of pip install is that it does it itself. ;)
Afterwards there are some 'Invalide requirement' statments:
- Invalid requirement: ''
- Invalid requirement: '# cachetools==1.1.6'
- Invalid requirement: '# cycler==0.10.0'
- Invalid requirement: '# deap==1.0.2'
- ....etc
But these might just be connected to the problem installing graphviz so, I don't care about those too much at this point.
Cheers!
oups, sorry, forgot about the commented out files starting with # in the file... this should've worked:
grep -v '^#' requirements.txt | while read line ; do pip install "$line" ; done
i'll reduce the core dependencies a lot so people don't run into this if they don't want any of the visualizations anyhow...
No unfortunately that does not change anything, still get the very same error. Don't know what's wrong there.
