pycallgraph与Spyder不起作用

Question

I ran the below code verbatim (which is an official sample code):
http://pycallgraph.slowchop.com/en/master/examples/basic.html

And I get the below error:

'The command "{}" is required to be in your path.'.format(cmd)) pycallgraph.exceptions.PyCallGraphException: The command "dot" is required to be in your path.

I'm running the program in Spyder on Windows from the directory : ' C:\\MyDocs\\pleasework.py '
' C:\\MyDocs ' is present in the sys.path as well

Answer 1

The pycallgraph module tries to use the dot command, which is not available in your system. You should install the dot utility which is provided by the graphviz package. http://www.graphviz.org/Download_windows.php
