i read in another post ( https://community.nodebb.org/post/53578 ) that you should be able to use node v6. Since i did not find anything related to which version some should use.
The current Dockerfile suggest using v4 but the file was updated long time ago.
The docs also do not really say which version some should use (at least i didnt find it here: https://docs.nodebb.org/en/latest/installing/os/debian.html). Since the docs are mentioning wheezy i suspect they are outdated too.
I would suspect using v6 would be fine since this is the latest LTS now. Which version should is use?
