Node Error "Cannot find module 'tinkerforge'"

[rwblinn]

Hi,

 

tried to run on a Raspberry Pi with Master Brick, Wifi Ext 2.0, Ambientlight the ExampleSimple.js.

When running from the commandline $node ExampleSimple.js, received error:

module.js:340

    throw err;

          ^

Error: Cannot find module 'tinkerforge'

 

The line in ExampleSimple.js not changed:

var Tinkerforge = require('tinkerforge');

 

Installed the javaScript bindings using npm. Steps taken as user Pi with install message.

cd /home/pi

sudo npm -g install tinkerforge

tinkerforge@2.0.9 /usr/lib/node_modules/tinkerforge

 

When adding the full path to require('/usr/lib/node_modules/tinkerforge') it is working.

 

How to setup without the need to add the full path in require.

 

Any help appreciated.

I had the same behaviour. After I installed the Tinkerforge modules globally, it was finally located in e.g. /usr/lib/node_modules.

But its needed to add this location in NODE_PATH var to env in Linux like

# export NODE_PATH=$NODE_PATH:/usr/lib/node_modules
# env
...
NODE_PATH=:/usr/lib/node_modules
...
