pi@raspberrypi:~ $

I have newest version of raspibian on two devices as Raspberry Pi 4 arm7. Please help. I need this on my project now :(

Problem with installation was fixed by installation on node-red system (Manage palletes -> Install) but still is impossible by Raspberry Pi LXTerminal.

The log above is not a fatal error. It is an optional dependency that failed to install, but is not needed for normal operation of the node. If you look close at the latest log lines:

....

+ node-red-contrib-s7@2.2.1
updated 1 package and audited 68 packages in 54.731s

... you'll see that it was indeed installed.

Don't worry, there will be a new major release soon that will remove this dependency. For now, just ignore it. I'm closing this issue as there's nothing to change or to fix for now.
