Can't install on Raspbian Buster

[jhoughjr]

This appears to affect every library I've tried for node gpio on buster.
Seems I'm the only person see the issue though.

This issue isn't related to onoff. The EACCES error is occurring because user pi doesn't have the permissions required to access directory /home/pi/fluids or sub-directories of /home/pi/fluids.

Please change the permissions for /home/pi/fluids and it's sub-directories so that user pi has the required permissions. Don't use sudo when installing packages with npm unless it's absolutely necessary. It's not necessary for user pi to install modules with sudo in directory /home/pi or sub-directories of /home/pi, everything should work without sudo. See here for further info.

Alternatively, create a new directory, for example, /home/pi/fluids2, and install everything that needs to be installed in /home/pi/fluids2 without using sudo. Then everything should work.

I'm going to go ahead and close this issue as it's not an onoff issue.
