node-red - arduino - johnny-five - Unable to load settings #727

[darlin]

Hello Guys,
Maybe I harried up to reported the issue #727
and this is my mistake, which you could help me to resolve.

Uncomment each of this two lines,in
functionGlobalContext: {:

 jfive:require("johnny-five"),
 j5board:require("johnny-five").Board({ port: "/dev/ttyACM0", repl:false })

 },

caused error:
Unable to load settings file: /usr/local/lib/node_modules/node-red/settings.js

Please let me know of your suggestions, if any.

The line "functionGlobalContext: {:" does not have a : on the end.

But that should give you a different error.  

Have you checked that the user account the you are running node-red from has permissions to read that file?

"{:" is my mistake during copy to post.
I'm working as root. When I commented this two line I can start node-red base on this settings.

Hi,

normally if there is a syntax error or runtime error loading the settings file it will give you a more useful message. There is a special case that says if the error is 'MODULE_NOT_FOUND' then report it as the message you are getting. This is because I (incorrectly) assumed this would be caused by not being able to find the settings file itself.

What I think is happening here is it is failing to find the johnny-five module, causing the MODULE_NOT_FOUND error.

Looking at your original problem description, I see you have installed johnny-five in ~/.node-red, but you are editing the settings file in the node-red module directory. That is the problem; the module should be relative to the settings file (as it is the settings file trying to load the module). If you copy the settings file to ~/.node-red then it will work.

Will look at the docs to see how to make this clearer.

Nick, thank you for your great  suggestion. Copy  setting file to ~/.node-red solved the problem of "Unload setting".
but node-red still is not work );

Hmm, the node should definitely be catching that error to stop it crashing the whole runtime. As for the underlying cause, I have to defer to what it says regarding the firmware... unless anyone else has hands experience with this node?
