Warning: Dot Command Dot Cannot Be Run

I am working on documentation for a software. And i have used graphviz directive inside my rest file. .. graphviz:: :align: center However when i run make html i get an error

Solution 1:

The problem could be referred to an incorrect configuration of "dot" executable from GraphViz PATH.

See: https://github.com/IQSS/dataverse/pull/7230

On my windows machine, I solved it following these steps:

1. Check if the dot installation has been performed, going in the installation path (the default installation path is: C:\Program Files (x86)\GraphvizX.XX\bin) and running here the command dot.exe
2. Go to Control Panel > System and Security > System, and on the right side navigation panel, click the Advanced systems settings link.
3. In Advance settings, a dialogue box opens that shows the Environment Variables button. Click the button.
4. Select the entry Path in the system variables section and add C:\Program Files (x86)\GraphvizX.XX\bin to the existing path.

I think the problem could be solved on your OS machine just adding the PATH using the export command, such as: export PATH=$PATH:~/opt/bin

Solution 2:

It looks like Sphinx can't find dot executable. Make sure it's in your path.
