Hi.  
I've been waiting for this feature for a very long time. )) I downloaded sublow example from [here](https://github.com/node-red/node-red/pull/2690) to my project folder. Then I tried to install it - `npm install test-subflow-mod`. When I try to launch my project I got an error - `test-subflow-mod\subflow.html does not exist`. Could anyone help me? Thanks in advance.

Hi @Tonna100

can you try with this one: [node-red/test/resources/subflow at master · node-red/node-red · GitHub](https://github.com/node-red/node-red/tree/master/test/resources/subflow)

I suspect the version I attached to the original PR is out of date.

I tried and got the same error `node_modules\test-subflow-mod\subflow.html does not exist`

I've just tried on a clean install and it is working for me.

What version of Node-RED are you using? That error message is what you'd get if you tried installing the module into a version of Node-RED before 1.3 when support for subflow modules was added.

My version of node-red was 1.2.9. I updated it and now works awesome. Thank you a lot for your help
