File not found error trying to see depgraph

[eduardo.ulysses@…]

I have a ticket with dependencies (ticket 70 is blocked by ticket 6). When I click on depgraph of ticket 70 I see

Trac detected an internal error:

WindowsError: [Error 2] El sistema no puede hallar el archivo especificado

I have both installed graphviz and graphviz plugin, and I think i have configured it properly.

Any idea?

You need to install the dot binary. If it is not available on your path, you need to set the dot_path option in trac.ini.

Coderanger, I received the same error message when I clicked on the Depgraph button, but my trac.log produced more error output as follows:

I set the dot_path in my trac.ini, as follows, with no luck. Any suggestions?

[graphviz] cache_dir = C:\Trac\Projects\ATMS\htdocs\graphviz dot_path = C:\Program Files\Graphviz2.20\bin cmd_path = C:\Program Files\Graphviz2.20\bin cache_manager = yes cache_max_size = 10000000 cache_min_size = 5000000 cache_max_count = 2000 cache_min_count = 1500

[Noah Kantrowitz]

The dot_path option has to be in the [mastertickets] section, as this is the masterickets plugin.

[Noah Kantrowitz]

You must set the value to FULL PATH to dot.exe. In your case:

[mastertickets]
dot_path = C:\Program Files\Graphviz2.20\bin\dot.exe

Also, for the love of formatting hit preview next time you try to ask for help.

Setting the dot.exe worked. Thank you very much for your help.

Also, thank you for the preview tip.
