pytest profiling-svg doesn't work on python 2.7

[aurelBZH]

pytest --profiling work perfectly on python2.7 but the option --profiling-svg doesn't work. The profiling report is generated but the svg isn't . The error trace is :

I also get the same error on OSX python 2.7.10

I was able to just run everything manually to get around this:

gprof2dot -f pstats prof/combined.prof | dot -Tsvg -o prof/combined.svg

Note on OSX I had to first brew install graphviz to get the dot cli arg.

Hi guys - thanks for raising this. The problem is that the dot executable from the graphviz package needs to be on your $PATH. This isn't clear in the README, neither does it raise a sensible error message so I'll try and make this better.

[kalefranz]

conda install graphviz fixed this for me.

python 2.7 is at end of life in less than 6 months.

[eeaston]

Hello - sorry all, we're dropping support for python2.7 so I'm closing this issue now.

on mac brew install graphviz is still needed even in python 3.9
