[Garfield2013]

On Windows 10 - and I have already installed Graphviz and added it to Windows environment system path:

npm install node-plantuml

node-plantuml@0.9.0 postinstall D:\My_project\node_modules\node-plantuml
node scripts/get-vizjs.js

events.js:167
throw er; // Unhandled 'error' event

Getting the same... Any updates for this issue?

Same issue as #28 , where @markushedvall explained that it is because you need Java to be installed (and added to path):

This error indicate that java is not available, or maybe need to be added to PATH?

During install java is needed to run testdot in Plantuml to check the ghraphviz installation. Maybe a pure js version of testdot could be implemented instead. However, without java the package wouldn't be usable anyway.

I had the same issue on Ubuntu and installing Java resolved it, I suppose it works on Windows too
