Found 0 module(s), events.js:160, throw er; // Unhandled 'error' event

What does it mean the following error?

Found 0 module(s)
events.js:160
      throw er; // Unhandled 'error' event
      ^

Error: write EPIPE

Is having zero modules an error?

The command I ran was:

```winbash
tsviz c:\myProject diagram.png

If I add -recursive, then the error becomes:

Found 234 module(s)
events.js:160
      throw er; // Unhandled 'error' event
      ^

Sample also fails with the same error, could it be an OS issue?

[Gilberto Stankiewicz]

Never mind, I found the problem. I had the wrong Graphviz directory in the path. I had added C:\Program Files (x86)\Graphviz2.38 instead of C:\Program Files (x86)\Graphviz2.38\bin.

Now tsviz is working!

same here on linux, but graphviz is in a known path:
