Error in script getpassword, unable to move forward with installation (iRobot i6+)

[AlSmyth81]

Running the commands as listed in the README file NOTE: installed on Pi image, file directiories do not match NOTE: iRobot model i6+

$ cd $(npm root -g)/homebridge-roomba2
bash: cd: /opt/homebridge/lib/node_modules/homebridge-roomba2: No such file or directory)

I dug a little and found the directory:
` /var/lib/homebridge/node_modules/homebridge-roomba2

` Here are the results of funning the command, along with the Press/Hold of the HOME button when prompted

/var/lib/homebridge/node_modules/homebridge-roomba2 $ npm run getpassword 192.168.1.84

> homebridge-roomba2@1.4.0 getpassword
> get-roomba-password 192.168.1.84

Make sure your robot is on the Home Base and powered on (green lights on). Then press and hold the HOME button (or DOCK+SPOT on some models) on your robot until it plays a series of tones (about 2 seconds). Release the button and your robot will flash WIFI light.
Then press any key here...

I first did this while the child/pet lock was enabled, and assumed an error based on the voice message from the unit. I disabled the CHild/pet lock, and repeated with the same rrooro details.
