Errors while installing new nodes


I'm installing some nodes on newly imaged Pi4 4GB.
There are some errors in the LogView during installation.
The nodes are working any way.

Should I be concerned about the errors ?
and what can I do about that?

Thank you !

Looks like you may not have installed the build essentials.

sudo apt-get install build-essential

It failed to install the usb module - but it looks like the node you were installing node-red-contrib-s7 has that listed as an optional dependency, and the overall install of the node succeeded. Whether that is an issue for you will depend on whether you wanted to use whatever optional functionality in the s7 node relied on the usb module.

If you wanted to get it fully installed, the usb module depends on some extra OS-specific packages to have already been installed - In summary, you should be able to run:

sudo apt-get install build-essential libudev-dev

then try reinstalling the s7 node.
