Installation on Raspberry Pi 4 fails

[stevenmcastano]

Here is the last part of the log where the install fails. I can't install through node red and I can't even install it at the command line:

Anyone have an ideas?

be sure you are installing node red and modules from NO root account. If you had, then is better you remove all and reinstall from NO root

[stevenmcastano]

I am installing as root, but that's because I wanted to run certain processes with the "exec" node and I didn't want to run into permissions issues... but either way, that shouldn't have effect on installing this package, should it?

[Barabba11]

Unfortunately installing under root put the package in a different folder, that is what I noticed, I can't tell you more. You better read and ask on nodered forum

[stevenmcastano]

Went back and redid the entire install under the pi user... same error message.

Just a foot note, you can always use 'sudo' with an exec node to avoid running Node Red under root. Are you using the official installation script for Node Red installation? I have several Pi 4 devices running Node Red without issue, including use of the 'node-red-contrib-i2c-bus' library. The original 'node-red-contrib-i2c' library is very dated, not actively supported, and I have yet to try to fix it or resolve the build errors 'i2c' has, given 'i2c-bus' works fine.
