Node-red installation always finishing with error

I tried different install methods, but always got error in same place.
Guess some system library not installed, can you suggest please how to fix this?

 npm install --production

> bcrypt@3.0.5 install /var/www/node-red/node_modules/bcrypt
> node-pre-gyp install --fallback-to-build

Hi - whilst NPM shows lots of errors, these are related to an optional dependency failing to build. Note after all the errors, NPM itself only reports a warning:

npm WARN optional SKIPPING OPTIONAL DEPENDENCY: bcrypt@3.0.5 

And the last few lines actually confirm the overall install was successful.

I can see you are using node 12.x - we don't currently recommend that some modules with binary components haven't been updated for it yet. From this error it would appear bcrypt is such a module.

This is on Debian 9.9 (strech) running in LXC container.

node -v v12.4.0 npm -v

Thank you, with node v11 everything works like charm!

Node versions 8 and 10 are the supported versions (see below). You may find some nodes are not compatible with 11. However if it is working you are probably ok.
