Yes, I have a Tex engine on my system.
How can i fix the problem with the PATH ?
Even if i execute the .py script directly by python (I mean :not inside 
a LateX file) pyx need to reach the TeX system ?

Is there a config file  to fix the PATH ? Where ?

Thanks a lot !! Ciao

PyX requires TeX to render textual glyphs into the image. Do you have it
installed? If so, is it "reachable" by your $PATH variable?

A quick test to re-render my PyX-based images with Python 3.6 didn't reveal
any problem...

ciao, lele.

PyX requires TeX to render textual glyphs into the image. Do you have it
installed? If so, is it "reachable" by your $PATH variable?

A quick test to re-render my PyX-based images with Python 3.6 didn't reveal
any problem...

ciao, lele.

problem with Python 3.6 + PyX

[stalker5]

Hello everybody !

I'm have a problem with this little program

#---début---
from pyx import *

g = graph.graphxy(width=8, x=graph.axis.linear(min=-15, max=15))
g.plot(graph.data.function("y(x)=sin(x)/x"))
g.writeEPSfile("function")
g.writePDFfile("function")
g.writeSVGfile("function")
#--- fin---

Python protest :

I search some solution, but without success.
Anybody have a idea ??

Thx a lot. Have a nice day.
