This tells you that a required (operating system level) utility
(named "dot") is not available.

Carefully read the installation instructions, especially any
remark about dependencies. This should tell you where "dot" is supposed
to come from. Install all operating system level dependencies.

If "dot" should have come from "graphviz", then maybe a
"hash" is necessary to let your shell see new commands.

how to use pycallgraph in ubuntu and window?

[meInvent bbird]

i install in ubunbu 14

pip install graphviz
pip install pycallgraph

martin@ubuntu:~/Downloads$ pycallgraph graphviz -- ./pusher.py
Traceback (most recent call last):

in window 

i had already added path

C:\Python27\Lib\site-packages\graphviz;C:\Python27\Lib\site-packages\pycallgraph

 to environment variable path

but in cmd

'pycallgraph' is not recognized as an internal or external command,
operable program or batch file.

then i use full path

>python "C:\Python27\Lib\site-packages\pycallgraph\py
callgraph.py"  -- "C:\Users\hello\Downloads\pusher.py"
Traceback (most recent call last):
  File "C:\Python27\Lib\site-packages\pycallgraph\pycallgraph.py", line 3, in 
from .output import Output
